How to start gasification furnace equipment, gasification combined cycle equipment and gasification furnace equipment

摘要

PROBLEM TO BE SOLVED: To provide gasification furnace equipment, a gasification composite power generation installation and a starting method of gasification furnace equipment which shortens a starting time of a gasification furnace and permits energy-saving and lower cost.;SOLUTION: Gasification furnace equipment includes: a gasification furnace; a water system each part 22 provided on an inner part of the gasification furnace; a steam drum 21 connected to the water system each part 22; an exhaust heat recovery boiler which supplies hot water compressed for the water system each part 22 upon the starting of the gasification furnace; a circulation system 24 in which hot water is circulated through the water system each part 22 and the steam drum 21; air separation equipment 42 which supplies compressed nitrogen for the steam drum 21 upon the starting of the gasification furnace; a steam condensor 73 which is connected to the steam drum 21 while being provided on an outlet of a steam turbine, and allows water to be supplied from the steam drum 21 upon the starting of the gasification furnace; and a gas extraction device 35 which is connected with the steam condenser 73 and extracts gas in the steam condensor 73. Therein, the gas extraction device 35 extracts gas from the steam condensor 73 upon the starting of the gasification furnace with an extraction amount larger than the extraction amount of gas extracted from the steam condensor 73 upon steam turbine operation.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
