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.

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.
