PUTTING RESIDUES
TO WORK
ENERGY FROM WASTE
Fuel Household and household-type industrial waste, production waste, used tyres, blast furnace gas, coke gas,
liquid and gaseous industrial waste.
Performance range Steam parameter up to 140 t/h – 500°C – 100 bar
Boiler technology Steam generator operating in natural circulation with two or three vertically arranged radiation passes and a down-
stream convective pass. The first, second or third boiler pass are in empty pass construction and form the combustion
and radiation area. The vertical or horizontal convective boiler pass is equipped with the superheater, evaporator
and economiser convective heating surfaces. All convective heating surfaces can be cleaned with a rapper while in
operation. Depending on the profile for requirement, boiler constructions with the installation of 3 or 4 passes
can be applied. The temperature of the superheated steam is regulated by a multistage injection cooler between
the heating surfaces of the superheater.
Combustion system Air or water-cooled pusher-type grate with ram feeder
Fuel gas treatment
Combustion that is highly resilient both thermally and mechanically with intelligent combustion control. The fuel
is metered by a plunger feeder. Every grate zone can be controlled individually, including a multistage primary air
distributor. The secondary air is injected via nozzle trays arranged in the first and rear wall of the furnace area.
Fluidised bed firing
The fuel is fed through openings of the evaporator side walls of the combustion chamber into the fluidised bed.
The combustion air and the recirculated flue gas is injected into the fluidised bed and into the combustion chamber
at different levels as secondary and tertiary air-injection.
Industrial combustion systems for liquid and gaseous fuels
Combustion technology for low-NOx industrial and power station combustion systems. The selection and configuration
of the burners is performed in accordance with the burner performance within the enclosing walls of the com-
bustion chamber.
Reliable compliance with legal emission limits is ensured by a downstream flue gas cleaning system. Quasi-dry,
conditioned dry and dry process versions are deployed. Calcium hydroxide Ca(OH) 2 , calcium oxide CaO or NaHCO 3
are fed into the flue gas as additives for the absorption of the acidic gas components. As an alternative, wet
pro cesses 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. In particular, the preferred fabric filter not only
guarantees minimal dust emissions, but also the lowest concentrations of pollutants in the clean gas thanks to
the intensive absorption and adsorption processes in the filter cake. 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
re duction) process.
