Grate-firing systems from Siempelkamp Energy & Drying Solutions
Energy systems for solid fuels: clean, versatile, low-maintenance
Grate-firing systems are used very frequently in processes involving energy generation with solid fuels. Siempelkamp Energy & Drying Solutions grate-firing energy systems are individually customised to the operator‘s needs and are flexible when it comes to the fuel needed – whether it be waste wood, bark, chips, coal, peat or another type of biomass.
Grate-firing systems are made to operate continuously and designed with a fully automatic de-ashing system. They allow for fuels with a very high moisture content of up to 150 % to be burned.
At a glance:
- Fuels with a moisture content level between 20 - 150% based on bd
- Combustion of waste wood, wooden board wastes (MDF, PB and OSB), bark, wood chips, coal and peat
- Air-cooled step grate sized from 12 to 90 m²
- Firing capacity from 10 to over 100 MW
- Automatic de-ashing system
- Graduated air-inlets
- Low emissions
- Efficiency > 95 %
- Flue-gas cleaning possible in combination with BÜTTNER’s dry electrostatic precipitators
Details
The grate surface is adapted to the volume of the combustion chamber and thus ensures that the flue gas is clean and burnt off.
Numerous technical innovations increase the profitability of Siempelkamp Energy & Drying Solutions grate-firing systems. One example is that additional flakes or fibres can be blown into the lower combustion chamber. Sanding dust, gas and oil are burned in the upper part of the chamber.
Flue gas from these substances is then utilised to heat thermal oil or generate steam.
Thanks to efficient utilization of flue gases in the dryer system, an efficiency level of more than 95 % is attainable in the wood based panel industry.
Siempelkamp Energy & Drying Solutions grate-firing systems are reliable and low-maintenance, which results in a high availability.
Our combustion systems operate in every climate of the world and demonstrate their high profitability.
