BERTSCHenergy - Solid-Fuel-Fired Power Plants
BERTSCHenergy offers customised solutions for a wide range of solid fuels. The choice of combustion technology depends on the fuel used and design parameters such as emission limits, load change rates, and the required availability.
Fluidised bed boilers represent a technological advancement on grate boilers. The decisive advantages are in the greater flexibility in fuel parameters (e.g. heating value band) and lower emissions. The boiler integrated fluidised bed is equipped with an open nozzle grate to remove coarse particles such as stones and ceramics. The fluidisation of the sand bed is carried out by a mixture of combustion air and recirculated flue gas.
FLUIDISED BED FOR FUEL PARTICLE SIZES UP TO 250 MM
- Biogenic residues(wood, waste wood, sawdust, chicken litter / poltry dung and other agricultural waste)
- Waste fuels (rejects, sludge, RDF)
A tailor-made flue gas cleaning method, adapted to the respective specified emission limit values, is applied. It consists of the following components or combinations thereof:
- SNCR-system for reducing nitrogen oxide emissions
- Electrostatic precipitator (ESP) with or without pre-separator
- Fabric filter with optional dry sorption unit for the reduction of HCl and SO2 emissions as well as binding heavy metals, etc.
