Without opening the turbine casings, over 323 kg of deposits were removed, and once the work was completed, a&nbsp;marked improvement in the key mechanical parameters of both units was observed. How did the process unfold, and what exactly were the changes observed after the turbines were restarted?

At a\u00a0power station in Turkey, it was decided to carry out foam cleaning to effectively remove contaminants without the need for time-consuming dismantling of the casing and components. The results of the process showed that, when carried out correctly, cleaning can not only remove deposits but also lead to a\u00a0marked improvement in the turbine\u2019s mechanical performance.<\/p>\n<p class=\"post__paragraph\">In this case study, we show <b>the problem the power station faced, how the cleaning was carried out, and what specific results were achieved following the process.<\/b><\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">how foam cleaning improved the operating performance of the turbines at the Tufanbeyli power station in Turkey<\/h2>\n<p>Ecol carried out chemical foam cleaning of the high-pressure (HP) sections of two Siemens SST-700 steam turbines, each with a\u00a0rated capacity of 150 MW, at the thermal power station.

Contaminants in the flow path affected not only the thermodynamic efficiency and performance of the units, but also the mechanical parameters of the turbine, including thrust bearing temperature, axial shaft displacement, rotor stability and the smooth operation of the machine. <\/p>\n<p class=\"post__paragraph\">Deposits can alter the aerodynamic profile of the blades and guide vanes, increase the roughness of their surfaces and impair steam flow conditions. Consequently, they can lead to efficiency losses and a\u00a0reduction in power output, as well as alter the axial forces acting on the rotor and increase the thermal and mechanical loads on the thrust bearing. <\/p>\n<p class=\"post__paragraph\">Therefore, in this project, it was crucial not only to confirm the effectiveness of deposit removal, but above all to assess the impact that cleaning would have on the turbines\u2019 operating parameters. <\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">what was found on the blades?<\/h2>\n<p>Analyses of deposits collected from individual rows of HP blades revealed a\u00a0similar nature of contamination in both units. This indicated common sources of origin, primarily linked to the chemistry of the water-steam cycle and the transport of corrosion products.<br>\nThe analysed deposits primarily contained compounds of aluminium, phosphorus and sodium, with a\u00a0relatively low iron content. The proportion of aluminium was 26\u201337 per cent by mass, phosphorus 24\u201332 per cent, sodium 19\u201332 per cent, iron 4\u20139 per cent and copper 6\u201310 per cent. <\/p>\n<p class=\"post__paragraph\">An analysis of the mechanism underlying the formation of the deposits indicated that these were not typical corrosion products. The predominant contaminants were associated, amongst other things, with the carry-over of impurities from the boiler, the incomplete removal of reagents used in water treatment, and the concentration of dissolved salts during steam expansion. <\/p>\n<p class=\"post__paragraph\">The analysis also revealed an increase in the proportion of sodium and phosphorus in successive turbine stages as the pressure fell from approximately 115 to 46 bar and the temperature from approximately 460 to 345\u00b0C. This indicates the condensation and deposition of some of these compounds in the middle and final parts of the HP section. <\/p>\n<p class=\"post__paragraph\">Silica (SiO\u2082) was also a\u00a0significant component of the deposits. Under high-pressure and high-temperature conditions, some of the silica may be carried along with the steam and, during its expansion, precipitate onto the surfaces of the blades, forming very hard deposits that are difficult to remove. <\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">laboratory tests first, then cleaning<\/h2>\n<p class=\"post__paragraph\">Before commencing work, Ecol carried out tests to confirm the effect of foam cleaning technology on the blade material. The tests were performed on material supplied by the customer \u2013 fragments of HP blades used in a\u00a0Siemens SST-700 turbine \u2013 made of martensitic steel 1.4121 (X20Cr13 \/ AISI 420). The aim was to confirm that the chemical technology used does not cause accelerated degradation of the material. <\/p>\n<p class=\"post__paragraph\">The samples were subjected to four-hour tests in solutions containing acid, a\u00a0corrosion inhibitor and \u2013 in one of the variants \u2013 an activator. After the tests were completed, the samples were neutralised with ammonia water at a\u00a0concentration of less than 1 per cent and dried. <\/p>\n<p class=\"post__paragraph\">The calculated corrosion rates were 0.002016 mm\/year for the first sample and 0.001558 mm\/year for the second. Both results were classified as Group II \u2013 materials with high corrosion resistance. <\/p>\n<p>Visual and microscopic examinations following the tests revealed no pitting, intergranular corrosion or other forms of localised material degradation. Only very minor, localised surface changes were observed.<br>\nThe results confirmed that the presence of the chemicals used did not increase the corrosion rate, and that the foam cleaning process did not lead to accelerated degradation of 1.4121 steel. <\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<div style=\"height:55px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2026\/10\/case-turcja-1-1024x768.jpeg\" alt=\"\" class=\"wp-image-49680\" style=\"width:922px;height:auto\" srcset=\"https:\/\/ecol.eu\/wp-content\/uploads\/2026\/10\/case-turcja-1-1024x768.jpeg 1024w, https:\/\/ecol.eu\/wp-content\/uploads\/2026\/10\/case-turcja-1-300x225.jpeg 300w, https:\/\/ecol.eu\/wp-content\/uploads\/2026\/10\/case-turcja-1-768x576.jpeg 768w, https:\/\/ecol.eu\/wp-content\/uploads\/2026\/10\/case-turcja-1.jpeg 1040w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Ecol mobile laboratory<\/figcaption><\/figure>\n<\/div>\n\n\n<div style=\"height:55px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">cleaning without opening the turbine casing<\/h2>\n<p class=\"post__paragraph\">Ecol employed a\u00a0chemical foam cleaning technology for the HP section without opening the turbine casing.

At the same time, a\u00a0reduction in vibration levels was recorded at most measurement points. <\/p>\n<p class=\"post__paragraph\">The project was carried out on two independent units, and the similar results obtained in both cases confirmed the reproducibility of the foam cleaning technology used. <\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <p class=\"post__paragraph\"><b><span style=\"font-size: xx-large\">the project in figures:<\/span><\/b><\/p>\n<ul class=\"post__list post__list--nonordered\">\n<li class=\"post__list-item\">2 \u2013 Siemens SST-700 turbines cleaned. <\/li>\n<li class=\"post__list-item\">150 MW \u2013 rated power of each turbine.<\/li>\n<li class=\"post__list-item\">&gt;323 kg \u2013 total mass of deposits removed. <\/li>\n<li class=\"post__list-item\">35\u201340\u00b0C \u2013 drop in temperature of the HP thrust bearing. <\/li>\n<li class=\"post__list-item\">20\u201330% \u2013 reduction in axial displacement of the HP shaft.<\/li>\n<li class=\"post__list-item\">11 people \u2013 the size of the team working on each unit.<\/li>\n<li class=\"post__list-item\">18 hours \u2013 the time taken to clean and passivate each unit. <\/li>\n<li class=\"post__list-item\">24 hours \u2013 the time taken for steam blowing of each unit. <\/li>\n<\/ul>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"faq alignwide\">\n  <div class=\"faq__grid\">\n    <div class=\"faq__column faq__column--left\">\n      <div class=\"container\">\n        <div class=\"row\">\n          <div class=\"offset-lg-2 offset-md-0 col-xl-6 col-lg-10 faq__text\">\n\n            \n              <h2 class=\"heading heading--line\">FAQ<\/h2>\n\n            \n            \n          <\/div>\n\n          <div class=\"offset-xl-1 offset-lg-2 offset-md-0 col-xl-6 col-lg-10\">\n\n            \n              <ul class=\"faq-list\">\n\n                \n                  <li class=\"faq-list__item\">\n                    <button class=\"btn faq-list__btn\">What does foam cleaning of a&nbsp;turbine involve?

A case study from the Tufanbeyli power station provides a&nbsp;concrete example of this effect.<\/p>\n                    <\/div>\n                  <\/li>\n\n                \n                  <li class=\"faq-list__item\">\n                    <button class=\"btn faq-list__btn\">When should you consider foam cleaning a&nbsp;turbine? <div class=\"faq-list__icon-wrapper\">\n                        <svg class=\"faq-list__icon faq-list__icon--show\" width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n  <path d=\"M12 2C10.0222 2 8.08879 2.58649 6.4443 3.6853C4.79981 4.78412 3.51809 6.3459 2.76121 8.17317C2.00433 10.0004 1.8063 12.0111 2.19215 13.9509C2.578 15.8907 3.53041 17.6725 4.92894 19.0711C6.32746 20.4696 8.10929 21.422 10.0491 21.8079C11.9889 22.1937 13.9996 21.9957 15.8268 21.2388C17.6541 20.4819 19.2159 19.2002 20.3147 17.5557C21.4135 15.9112 22 13.9778 22 12C22 10.6868 21.7413 9.38642 21.2388 8.17317C20.7363 6.95991 19.9997 5.85752 19.0711 4.92893C18.1425 4.00035 17.0401 3.26375 15.8268 2.7612C14.6136 2.25866 13.3132 2 12 2ZM12 20C10.4178 20 8.87104 19.5308 7.55544 18.6518C6.23985 17.7727 5.21447 16.5233 4.60897 15.0615C4.00347 13.5997 3.84504 11.9911 4.15372 10.4393C4.4624 8.88743 5.22433 7.46197 6.34315 6.34315C7.46197 5.22433 8.88743 4.4624 10.4393 4.15372C11.9911 3.84504 13.5997 4.00346 15.0615 4.60896C16.5233 5.21447 17.7727 6.23984 18.6518 7.55544C19.5308 8.87103 20 10.4177 20 12C20 14.1217 19.1572 16.1566 17.6569 17.6569C16.1566 19.1571 14.1217 20 12 20Z\" fill=\"black\"\/>\n  <path d=\"M15 11H13V9C13 8.73478 12.8946 8.48043 12.7071 8.29289C12.5196 8.10536 12.2652 8 12 8C11.7348 8 11.4804 8.10536 11.2929 8.29289C11.1054 8.48043 11 8.73478 11 9V11H9C8.73478 11 8.48043 11.1054 8.29289 11.2929C8.10536 11.4804 8 11.7348 8 12C8 12.2652 8.10536 12.5196 8.29289 12.7071C8.48043 12.8946 8.73478 13 9 13H11V15C11 15.2652 11.1054 15.5196 11.2929 15.7071C11.4804 15.8946 11.7348 16 12 16C12.2652 16 12.5196 15.8946 12.7071 15.7071C12.8946 15.5196 13 15.2652 13 15V13H15C15.2652 13 15.5196 12.8946 15.7071 12.7071C15.8946 12.5196 16 12.2652 16 12C16 11.7348 15.8946 11.4804 15.7071 11.2929C15.5196 11.1054 15.2652 11 15 11Z\" fill=\"black\"\/>\n<\/svg>\n                        <svg class=\"faq-list__icon faq-list__icon--hide\" width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n  <path d=\"M12 2C10.0222 2 8.08879 2.58649 6.4443 3.6853C4.79981 4.78412 3.51809 6.3459 2.76121 8.17317C2.00433 10.0004 1.8063 12.0111 2.19215 13.9509C2.578 15.8907 3.53041 17.6725 4.92894 19.0711C6.32746 20.4696 8.10929 21.422 10.0491 21.8079C11.9889 22.1937 13.9996 21.9957 15.8268 21.2388C17.6541 20.4819 19.2159 19.2002 20.3147 17.5557C21.4135 15.9112 22 13.9778 22 12C22 10.6868 21.7413 9.38642 21.2388 8.17317C20.7363 6.95991 19.9997 5.85752 19.0711 4.92893C18.1425 4.00035 17.0401 3.26375 15.8268 2.7612C14.6136 2.25866 13.3132 2 12 2V2ZM12 20C10.4178 20 8.87104 19.5308 7.55544 18.6518C6.23985 17.7727 5.21447 16.5233 4.60897 15.0615C4.00347 13.5997 3.84504 11.9911 4.15372 10.4393C4.4624 8.88743 5.22433 7.46197 6.34315 6.34315C7.46197 5.22433 8.88743 4.4624 10.4393 4.15372C11.9911 3.84504 13.5997 4.00346 15.0615 4.60896C16.5233 5.21447 17.7727 6.23984 18.6518 7.55544C19.5308 8.87103 20 10.4177 20 12C20 14.1217 19.1572 16.1566 17.6569 17.6569C16.1566 19.1571 14.1217 20 12 20V20Z\" fill=\"black\"\/>\n  <path d=\"M15 11H9C8.73478 11 8.48043 11.1054 8.29289 11.2929C8.10536 11.4804 8 11.7348 8 12C8 12.2652 8.10536 12.5196 8.29289 12.7071C8.48043 12.8946 8.73478 13 9 13H15C15.2652 13 15.5196 12.8946 15.7071 12.7071C15.8946 12.5196 16 12.2652 16 12C16 11.7348 15.8946 11.4804 15.7071 11.2929C15.5196 11.1054 15.2652 11 15 11Z\" fill=\"black\"\/>\n<\/svg>\n                      <\/div>\n                    <\/button>\n                    <div class=\"faq-list__content\">\n                      <p class=\"desc\">It is worth considering these measures when a&nbsp;deterioration in the turbine\u2019s performance is observed, as this may be caused by deposits on the surfaces of the flow path components.
