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.
