FEASIBILITY STUDY OF COMBINED FIRING IN ANNULAR SHAFT KILN FOR LIME BURNING
KOMUNALNA ENERGETIKA / POWER ENGINERING, 4
The article deals with combined firing of wood chips and natural gas in the annular shaft kiln for lime production. Wood chips are gasified separately in the autonomous gasifier. Hot syngas from the gasifier is mixed with natural gas in the existing combustion chamber and then burned completely. The moisture content in the wood chips dictates the amount and calorific value of syngas. The simulation of syngas and natural gas co-combustion in the lower combustion chambers shows that can be up to 50 % of natural gas supplemented with the wood syngas made from the fresh wood chips.
