This also has an impact for the challenges facing power plant chemistry through the plans for changes in power plants. Both in the various vgbe committees and at the vgbe Chemistry Conference, it is noticeable that the topics in focus are changing.<\/p><p>In the last few years, there have been some important changes in conventional power plants, such as the lowering of flue gas and waste water limits, which are still affecting power plant chemists and lead to new tasks. In addition to the limit values themselves, in some cases the limits of determination of the measurement methods must also be lowered in some cases in order to be able to prove compliance with the limit values. Existing power plant units also need to be constantly optimised: The retrofitting of online measuring devices must be considered, as laboratory staff is generally smaller today than when the power plant units were built and laboratory measurements can therefore only be carried out at longer intervals in some places. Water treatment plants are often aging, resulting in higher maintenance efforts and a need for optimisation.<\/p><p><a class=\"storyLink\" title=\"Editorial Issue 3\/2024\"

This results in the annual use of 50,000 tons of biocides in cooling waters\/ utility waters in the European Union. In order to understand microbiology of an aqueous system, the water phase as well as surface deposits and biofilms must be assessed. There is a particular correlation between these deposits and pathogenic microorganisms such as Legionella. Probiotics can naturally clean systems by metabolising these biofilms and establishing themselves on the surfaces. Through this cleaning process, microorganisms closely associated with biofilms often lose their habitat. In the medium term, this improves system cleanliness and hygiene in a sustainable and environmentally friendly way. In a clean system, there are fewer microbiologically induced problems.<\/p><p><a href=\"https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/03\/vgbe-ej-2024-03-036-043-SPINDLER-RGB-Specimen-Copy.pdf\" target=\"_blank\" rel=\"noopener\">Download [1.0 MB]<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e386a89 elementor-widget elementor-widget-heading\" data-id=\"e386a89\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Removing particulate contamination from cooling and make-up water\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d9b7af5 elementor-widget elementor-widget-heading\" data-id=\"d9b7af5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Friedrich Wilhelm<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-264e24b elementor-widget elementor-widget-text-editor\" data-id=\"264e24b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Nowadays, there are more filter systems than ever.

of the vgbe energy journal,<\/p>\n<p>The world of energy is changing. This also has an impact for the challenges facing power plant chemistry through the plans for changes in power plants. Both in the various vgbe committees and at the vgbe Chemistry Conference, it is noticeable that the topics in focus are changing.<\/p>\n<p>In the last few years, there have been some important changes in conventional power plants, such as the lowering of flue gas and waste water limits, which are still affecting power plant chemists and lead to new tasks. In addition to the limit values themselves, in some cases the limits of determination of the measurement methods must also be lowered in some cases in order to be able to prove compliance with the limit values. Existing power plant units also need to be constantly optimised: The retrofitting of online measuring devices must be considered, as laboratory staff is generally smaller today than when the power plant units were built and laboratory measurements can therefore only be carried out at longer intervals in some places. Water treatment plants are often aging, resulting in higher maintenance efforts and a need for optimisation. Despite turbulent times, compliance with the required feed, boiler water and steam purity in the water-steam cycle in accordance with VGBE-S-010-00-2023-08 is still essential in order to avoid costly damage to the turbine and boiler. The challenges for the plant components are all the greater as we now have to deal with constant start-ups and shutdowns at unpredictable intervals. The aforementioned vgbe standard has also recently been revised to incorporate current aspects.<\/p>\n<p>Particularly in the winter of 2022\/2023, difficulties in the supply of chemicals led to additional work for the power plant chemists. In addition to the use of mobile reverse osmosis systems in water treatment to save on regeneration chemicals for the ion exchange systems, substitutes (e.g. for flocculants) and reduced qualities of auxiliary materials on offer also had to be evaluated. Preparations were also been made for the winter of 2023\/2024 in this regard, but the measures did not materialise here.<\/p>\n<p>New areas of work for the vgbe committees are mainly the result of the \u201cfuel switch\u201d projects and other new installations as part of the CO<sub>2<\/sub> reduction measures. For example, biomass combustion and its influence on slagging and flue gas cleaning need to be considered, especially the challenge of switching to 100 % biomass. Other new projects include the planning of carbon capture and storage (CCS) facilities, where a lot of experience still needs to be gained. The planned \u201cfuel switch\u201d from coal to natural gas to hydrogen, both in existing plants and new builds, still raises nume\u00adrous questions that power plant chemists need to think through. Large heat pumps, geothermal energy and electrolysis are other types of generation that are increasingly coming to the fore in the vgbe committees. For some topics, we are still in the early stages of defining all the important issues and gaining the appropriate expertise to develop new vgbe standards.<\/p>\n<p>At the vgbe Chemistry Conference in Ingolstadt in October 2023, Mr Michael Rziha (PPChem AG) impressively lamented the loss of expertise in power plant chemistry in his opening speech. We are all called upon to value the knowledge of power plant chemistry and to ensure a suitable successor at an early stage. Knowledge can only be acquired through sufficient training and years of experience. It is also important to remember why power plant che\u00admistry was originally developed \u2013 to prevent costly damage to the plants, for example through corrosion. Protecting the water-steam cycle and thus the steam turbine is also an important goal for new plants, especially if we want to achieve a high level of availability.<\/p>\n<p>So, help us to network within the vgbe so that we can complement each other\u00b4s with expertise and tackle current and future challenges together!<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Chemistry in energy generation and storage<br \/>\nAnalytics of hard coal at EnBW \u2013 experiences with deviations of the net calorific value<br \/>\nCleaning based on probiotics<br \/>\nRemoving particulate contamination from cooling and make-up water<br \/>\nA review of power to heat technologies according to the process temperature<\/p>\n","protected":false},"featured_media":29914,"template":"","class_list":["post-29938","pt-journal","type-pt-journal","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/pt-journal\/29938","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/pt-journal"}],"about":[{"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/types\/pt-journal"}],"version-history":[{"count":5,"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/pt-journal\/29938\/revisions"}],"predecessor-version":[{"id":29950,"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/pt-journal\/29938\/revisions\/29950"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/media\/29914"}],"wp:attachment":[{"href":"https:\/\/www.vgbe.energy\/en\/wp-json\/wp\/v2\/media?parent=29938"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
