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

摘要

PROBLEM TO BE SOLVED: To make a wet biomass incineration system operable while stably heat recovery by restricting excessive rise of temperature of the combustion chamber of a combustion furnace even if properties and condition of the wet biomass supplied to the combustion furnace change in the wet biomass incineration system having an internal circulation flow fluid bed type wet biomass combustion furnace.;SOLUTION: An operational method of a wet biomass incineration system, in a wet biomass combustion furnace having a dry room and a combustion chamber; a fluid bed containing a fluid medium flowing along the lower part of the dry room and the lower part of the combustion chamber; and a partition wall that divides the space into the upper space of the dry room and the upper space of the combustion chamber and in that the bottom edge of the partition wall is disposed within the fluid bed, the method comprises: a first step to adjust the super-heated steam quantity or the quantity of water supplied to the dry room according to the temperature of the combustion furnace; and a second step of the heat recovery from the super-heated steam.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
