Performance range:
Travelling grate firing system up to 140 MWth , Steam parameters up to 540 °C - 140 bar
Dust firing system up to 300 MWth , Steam parameters up to 540 °C - 140 bar

Boiler technology:
This natural circulation steam generator boasts a compact structure and is largely prefabricated in the workshop. As a natural circulation two-drum boiler, prefabricated as a modular system. Steam generators with natural circulation with several boiler passes being vertically arranged. The first boiler pass is formed as open pass and is divided into furnace and radiation chamber. Superheater, evaporator and economiser convection heating surfaces are installed in all further boiler passes. All convection heating surfaces can be cleaned during operation with soot blowers. The superheated steam temperature control is carried out by means of an injection cooler between the superheater heating surfaces.
Combustion system:
Hard coal, lignite
Travelling grate firing with hopper feed and fuel bed controller.
The primary air is fed underneath the grate - divided into several separately controllable zones. The secondary air injection is carried out via nozzle rows in the front and rear wall of the furnace.
Coal dust
Low NOx industrial/powerstation firing systems are used for coal dust. The burners are arranged depending on the capacity in the surrounding walls of the combustion chamber.
Gas, oil
Low NOx industrial/powerstation firing systems as single-fuel system or as combined burner for gas and oil.
Fuel gas treatment:
Semi-dry or dry process versions are deployed. Calcium hydroxide Ca(OH)2, calcium oxide CaO or NaHCO3 are fed into the flue gas as additives for the absorption of the acidic gas components. As an alternative, wet processes may
also be used. The separation of heavy metals and organic substances such as dioxins and furans is performed using adsorption with activated lignite coke or activated carbon. Fabric filters, electrostatic precipitators or cyclones are used to ensure the required particle separation. The removal of nitrogen from the flue gases can be performed using either an SNCR (selective non catalytic reduction) process or an SCR (selective catalytic reduction) process.
