PRESSURIZED-TYPE GASIFIER, METHOD FOR OPERATING THE SAME, AND GASIFICATION POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a pressurized-type gasifier ensuring gasification oven product gas not to diffuse throughout the hollow space, to provide a method for operating the gasifier, and to provide a gasification power generator. SOLUTION: The pressurized-type gasifier is such that a gasification oven is housed in a pressure vessel, and a gasification product gas exit and the inside of the pressure vessel are made to communicate with each other. In this gasifier, partition plates with gas-flowable spacings are arranged in between a gasification oven water-cooling wall and the pressure vessel's inner surface to divide the pressure vessel in multiple chambers. The chamber communicating with the above exit is equipped with a gas feed mechanism so as to enable gasification product gas intruded when gasification oven pressure rises to be exhausted.
