Abstract

Disclosed is a gasification furnace for the gasification pilot plant test of underground coal and the process thereof. The equipment of the process comprises a gas supply system, a gasification furnace, a temperature measuring pressure measuring and ingredient detecting system, a high temperature shooting system and a gas purifying system. The gasification furnace has a refractory material inner liner in the housing, has a grouting hole on the housing for performing seal to the coal bodies inside the furnace, and can perform gasification test in high temperature high pressure condition. The furnace body is formed with a gasifying agents and water-gas input/output hole, a grouting hole, a cooling water input/output hole, a temperature/pressure/ingredient measuring auxiliary hole, a high temperature shooting system viewing hole, a resistor method measuring hole and a manhole. The invention fully considers the pressurized condition in the underground coal gasification process, meets the requirement of gasification pressuring to coal in the pilot plant test, can investigate the technological experiment of normal/high pressure underground coal gasification and combustion point returning. The gasification furnace is equipped with a plurality of temperature measuring, pressure measuring and gas ingredient measuring systems and high temperature visual monitoring systems, can perform on-line monitoring and real time control to various parameters in the pilot plant test process.

Description

technical field [0001] The invention relates to the technical category of underground coal gasification, in particular to an underground coal gasification pilot test gasifier and a process method thereof. Background technique [0002] Underground coal gasification is a controlled combustion of underground coal, which generates combustible gas through thermal and chemical effects on coal. It integrates well construction, coal mining, and gasification technology into one multidisciplinary development of clean energy and chemical raw materials. new technology. Underground coal gasification is carried out under the conditions of an underground gasifier—the coal in the gasification cavity at one end of the gasification channel air intake hole in the coal seam is ignited, and gasification agents such as air, oxygen, and water vapor are blown into the air intake hole , so the underground coal will be burned in a controlled manner. After thermal action and chemical action on coal,...
