  • Steam temperature – up to 540°C

Grate furnace

BERTSCHenergy supplies air- and water-cooled reciprocating grates which are integrated into the water tube boiler. The combustion process is optimised by air staging and the injection of recirculated flue gas.

Grate furnace for fuel particle sizes up to 700 mm

  • Untreated biomass like waste wood, wood chips, landscape cultivation material, bark, sawdust
  • Wood from short rotation plantations
Bubbling fluidised bed

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)
Boiler technology

For the purpose of the highest efficiency, BERTSCHenergy exclusively pursues customer-oriented solutions. ThereforeBERTSCHenergy power plants apply furnace and boiler technologies accurately adjusted to the available fuels and the customer's requirements.

  • Natural circulation boiler as a membrane wall construction with post-combustion chamber and downstream radiation and convection passes
  • Economiser as a free-standing metal sheet construction
  • Superheated steam temperature control with spray coolers or drum cooler
  • Boiler cleaning systems such as soot blowers, water cannons, shower cleaning
  • Optional use of a flue gas condensation unit for maximised heat recovery from the flue gas
Emission control

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.

Gas- and oil-fired power plants (simple cycle/HRSG, combined cycle/CCPP, direct fired

Gas and steam turbines and combustion.

BERTSCHenergy offers all possible combinations with gas and steam turbines to generate electricity and steam. When it comes to the use of fossil fuels, maximum energy efficiency is what matters. Maximum availability, operational flexibility and dynamism of our power plants are at the core of our customers' economic success.

Industrial heat recovery
(cement- and steel industry, thermal disposal processes)

Waste heat recovery process reduces energy costs and energy consumption.

The waste heat from industrial processes offers significant savings potential in primary energy costs. Tailored BERTSCHenergy heat recovery boiler plants ensure optimum heat recovery and reduces the overall energy consumption. Depending on requirements, the recovered heat can be converted into electrical energy using a turbine, or used for the reduction of primary energy utilisation in other processes.
