Short Profile

CheMin has been acting as a consultant and expert witness for 20 years. We provide services in the development, optimisation and evaluation of quality standards for fuels, materials, residual materials and engineering methods which are used by fossil and waste-fired power plants, biomass and waste-to-energy plants (WTE plants) and other power plants.

CheMin always adopts a neutral position in the market and avoids systematically safeguarding the interests for individual clients or market segments. Three employees of CheMin are publicly appointed and sworn expert witnesses.

CheMin provides professional advice to power plants all over Europe and – project-related – also worldwide. The builders and operators of power plants and WTE plants form our largest customer group. Engineers, associations, governmental organisations, courts of law and arbitration, suppliers of system components, users of residual materials as well as insurers are included among our customers, too.

Principally taking the approach of a generalist, we concentrate on observing, assessing, connecting and understanding processes and phenomena as an essential part of our work. Some of the CheMin staff have academic training with a geo-scientific background. Our Earth constitutes an ideal object for applied sciences and is perfectly suited to educate generalists who are able to understand power plant processes as a result of complex material conditions.

Power plants are always “chemical reactors”, and the resulting interactions such as corrosion and contamination, form an important part of our work. We apply sensory equipment to deduce specific information: heat flux sensors, deposit monitors, corrosion monitors and other sensory devices were developed by CheMin.

Power plants and particularly WTE plants, waste wood-fired biomass plants and co-firing coal plants constitute “chemical reactors” which are affected by the material properties and inconsistencies in the fuel and, therefore, by the widely varying requirements regarding operational modes and boiler materials.

As common fields of action we are engaged in taking measures to evaluate, reduce and avoid corrosion. This concerns high temperature corrosion as well as corrosion processes at the cold end of boilers and in flue gas cleaning. Another important field is the polluting behaviour of boilers. Our objective is to keep maintenance costs as low as possible and maximise availability. In the longer term, these measures support the principle of foresighted maintenance.

We transfer the “reading of complex material patterns”– an ability first trained in the mostly grate-fired WTE plants - to other firing systems and fuels. We also manage the transfer to other European and global markets with a different technical and legal background and experience.

We aim at establishing networks and exchanging experience in closed user groups. Our conference papers and publications are made available on this website. We cooperate with universities and other research institutes within the scope of supported project programmes, thus pursuing the direct transfer of knowledge to market-relevant applications. We understand ourselves as collectors of information as well as carriers and distributors of knowledge. We contribute to academic lecturing at universities.

Technical processes for the provision of useful energy form the basis of our work.
