Problems solved by technology

[0002] At present, it is known that coal-fired power plants built on the ground use raw coal as raw material. There is a large amount of coal transported from underground to the ground, and transported from the wellhead to the power plant on the ground. The construction costs, transportation equipment and transportation costs are high, and coal ash and gangue The site covers a large area, coal mining causes ground subsidence, direct combustion of raw coal wastes a large amount of chemical raw materials, and seriously pollutes the environment. There are also many

Embodiment Construction

[0011] In Figure 1, the coal gas produced by the underground coal gasification plant is sent to the surface gas treatment plant through pipelines; after desulfurization, dust removal and extraction of coal tar, phenol, ammonia and other chemical raw materials in the gas treatment plant, it is sent to the ground thermal power plant as Fuel; because the gas treatment plant needs to produce coal tar, phenol, ammonia and other raw materials at low temperatures, it is necessary to cool down the gas before it is sent to the gas treatment plant, and arrange a cooling wall composed of cooling water pipes around the hot gas pipeline. After being heated, the cooling Water enters the boiler for power generation.

[0012] In Figure 2, the coal gas produced by the underground coal gasification plant is sent to the surface gas treatment plant through pipelines; after desulfurization, dust removal and extraction of coal tar, phenol, ammonia and other chemical raw materials in the gas treatmen...

Abstract

A technical proposal of providing ground fuel electric plant or chemical plant and fertilizer plant with fuel or raw material by using coal gas produced by coal based gasification plant of coal mine. The coal gas produced by coal based gasification plant of coal mine is sent through pipeline or well to ground fuel electric plant as fuel or to ground chemical plant and fertilizer plant as raw material, especially to power plant beside pit mouth or chemical plant and fertilizer plant beside pit mouth as fuel or raw material. A cooling wall composed of cooling water pipes is disposed around the pipeline and well or in the well for transmitting the coal gas produced by coal based gasification plant of coal mine; and the heated cooling water is sent to the ground fuel electric plant or exhaust-heat boiler.

Description

Technical field [0001] The invention relates to a thermal power plant using coal gas as fuel and a chemical and fertilizer plant as raw material, especially a thermal power plant using coal gas produced by an underground coal gasification plant in a coal mine as fuel and a chemical, chemical and fertilizer plant as raw material. fertilizer plant. Background technique [0002] At present, it is known that coal-fired power plants built on the ground use raw coal as raw material. There is a large amount of coal transported from underground to the ground, and transported from the wellhead to the power plant on the ground. The construction costs, transportation equipment and transportation costs are high, and coal ash and gangue The site covers a large area, coal mining causes ground subsidence, direct combustion of raw coal wastes a large amount of chemical raw materials, and seriously pollutes the environment. There are also many thermal power plants built near the pit mouth of...
