Abstract

The invention discloses a coal underground gasification temperature control system. The coal underground gasification temperature control system comprises an automatic distribution control system, a gas component analysis and detection system, an underground real-time temperature monitoring system and an auxiliary combustion system, wherein the automatic distribution control system and the gas component analysis and detection system are arranged on the ground. The technical problem that the coal underground gasification process cannot be controlled can be solved, the production process can be regulated according to the product requirement, and automatic operation and continuous production are achieved. A coal underground gasification temperature control technology and device can also make timely response and remedy for the gasification process obstacle caused by sudden change of the gasification environment, the gasification process can rapidly return to the dynamic balance, and the stable and continuous product gas output is guaranteed; the automation degree is high, the adaptability range is wide, operation is easy, safety is good, and economical efficiency and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of underground coal gasification technology and comprehensive utilization of coal combustion, in particular to an underground coal gasification temperature control system. Background technique [0002] As a new chemical coal mining method, underground coal gasification technology has been highly valued by many resource-consuming countries because of its high energy conversion efficiency and low environmental pollution level. Although my country is poor in oil and gas, although it has abundant coal resources, due to the limited mining and protection of high-quality coal, the development of underground coal gasification technology, especially the underground gasification of low-quality coal, can alleviate to a certain extent my country's growing coal resources. The aggravated energy shortage has great strategic significance and extremely high economic value. [0003] After decades of domestic research on under...
