Kohlbach - Model K8 -Combustion System
Furnace thermal output: 550 - 10.260 kW. Counter flow furnace with moving grate and water cooled compression zone.
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 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.
Water content (% weight): 20 to 60 depending on configuration
Size (nominal length mm): 30 to 100
Maximum ash content (% weight): 10
VariantsMechanical de-ashing OR automatic ash discharge to reduce operational maintenance workload and thus guarantee extended run times between maintenance shut-downs. Applicable for KOHLBACH boiler systems (water, saturated steam, superheated steam).
Supplementary equipmentFlue gas recirculation and/or air pre-heating for additional expansion of the range of usable fuels, available SNCR injection for use in particularly sensitive and emission-protected regions, special version available for the admixing of specified agrarian biomass (miscanthus, corncobs, etc.) upon specific customer request.
