Combustion technology

Counter flow furnace with moving grate and water cooled compression zone

Furnace thermal output

525 to 7,675 kW

Fuel

Water content [% weight]: 20 to 60 depending on configuration

Size [nominal length mm]: 30 to 100

Maximum ash content [% weight]: 5

Variants

• Mechanical de-ashing OR automatic ash discharge to reduce operational maintenance workload and thus guarantee extended run  times between maintenance shut-downs
• Applicable for all boiler systems (water, steam and thermal oil)

Supplementary equipment

• Flue gas recirculation and/or air pre-heating for additional expansion of the range of usable fuels
• Special version available for the admixing of specified agrarian biomass (miscanthus, corncobs, etc.) upon specific customer request

Your benefits by Kohlbach

• Compact and yet adiabatic counter-flow furnace for optimised efficiency and lowest emissions even with very heterogeneous fuel material
• Equipped with hydraulic moving grate, also suitable for very wet and dirty fuels with high ash content, as well as for 100% wet bark
• Hydraulic fuel feed with shearing devices for fault-free feeding even with wet and rough fuel materials
• Reliable nominal power with all usable fuels and degrees of water content
• Reliable long operating life of the furnace thanks to full refractory lining and grate frame cooled with water
• A cooled infeed zone to extend the operating life and improve the partial load operation, startup and shutdown behaviour.
• Rapid and simple installation thanks to pre-assembled modules
