FEASIBILITY STUDY OF A WOOD SYNGAS CO-FIRING IN ANNULAR SHAFT KILN FOR LIME BURNING
KOMUNALNA ENERGETIKA / POWER ENGINERING, 9
The article deals with the wood syngas as a partial supplementary fuel for lime burning in
the annular shaft kiln. Natural gas is a primary fuel. Wood chips are gasified with approved
technology in the counter current gasificator. As an oxidizer the mixture of air with recycled
flue gas with ~10 % oxygen is used. The moisture content in the wood chips dictates the
amount and calorific value of syngas. The simulation of syngas and natural gas cocombustion
in the lower combustion chambers shows that can be 20 % to 50 % of natural gas
supplemented with the wood syngas.
