Investigations in power plant and water cycles & flue gas desulfurization plants

In thermal power plants, combined heat and power plants and heat transfer stations, large quantities of water are used to transform the energy forms and for cooling.

A large part of the water used is circulated.

In order to keep their chemical and physical properties within the normal range, constant control tests are required during the process.

The main focus here is on the water-steam cycle and the water treatment systems. In addition to these, however, cooling circuits or the process streams of flue gas desulfurization must also be examined.

Flue gas cleaning processes for the removal of sulfur compounds are used to clean the flue gases from thermal power plants. In these flue gas desulfurization plants, the SO2 and SO3 gases produced during combustion are washed out of the flue gas and removed from the process as gypsum.

Our customers include operators of large power plants, combined heat and power plants, engineering service providers (within the scope of commissioning) as well as plant manufacturers and research facilities in Germany and abroad.
