WET BIOMASS INCINERATION SYSTEM AND OPERATIONAL METHOD OF WET BIOMASS COMBUSTION FURNACE

摘要

PROBLEM TO BE SOLVED: To make the temperature of a dry room and a combustion chamber of a wet biomass combustion furnace easier to adjust quickly even when the moisture content of biomass and the caloric power per unit weight of the solid content of biomass to be supplied to a wet biomass combustion furnace are temporarily changed in an internal circulation fluid bed type wet biomass combustion furnace having the dry room and the combustion chamber.;SOLUTION: A wet biomass incineration system comprises: a wet biomass combustion furnace having a dry room/a combustion chamber, a fluid bed, and a partition wall; a first flow control valve for regulating the flow-rate of the dry exhaust gas discharged outside of the dry room; and a second flow control valve for regulating the flow-rate of the flue exhaust gas discharged outside of the combustion chamber. By narrowing the degree of opening of one valve of the first flow control valve and the second flow control valve more than that of the other valve, the bed height of the fluid bed on one chamber side and the bed height of the fluid bed on the other chamber side are adjusted so as to be relatively displaced in a direction in which the gas pressure difference in each upper space is reduced.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
