DEVICE RECOVERING ENERGY BY USING SOLID BIOFUEL HAVING EXCELLENT EFFICIENCY PROCESSING ACID GAS, CAPABLE OF CONTINUOUSLY RECOVERING THE HEAT IN A REAR END INCINERATING BOILER

摘要

PURPOSE: A device recovering energy by using solid biofuel having excellent efficiency processing acid gas is provided to secure the effectiveness by minimizing the excessive use of combustion air and the generation of unburned powder caused by the heat loss and maximizing the energy recovering efficiency.;CONSTITUTION: A device recovering energy by using solid biofuel having excellent efficiency processing acid gas comprises a biofuel supply unit, a traveling-stoker type incinerating boiler, an unburned powder returning conveyor, an economizer (50), an air preheater, a steam turbine generator, one or more wet electrical dust collector (80), a selective catalytic reduction top (90). The unburned powder returning conveyor circulates unburned powder generated in the incinerating boiler to a traveling-stoker (20) and improve the combustion efficiency. The wet electrical dust collectors remove the acid gas and dust generated in a combusting process. The selective catalytic reduction top additionally removes nitrogen oxide generated in the combusting process.;COPYRIGHT KIPO 2013;[Reference numerals] (AA,LL) Reducing chemical storage tank; (BB) Steam; (CC) Degassifier; (DD) Boiler water supply tank; (EE) Reducer; (FF) Generator; (GG) Power production; (HH) Steam supply; (II) Selective non-catalytic reduction; (JJ) Second air blower; (KK) Combusted gas re-heater; (MM) Clamp-off air blower; (NN) Stocker re-discharge conveyor; (OO) Water supply heater; (PP) Induced air blower; (QQ) Chimney
