Problems solved by technology

[0005] At present, domestic gas power generation is generally used in mines with high-concentration gas and stable gas sources. Only gas with a concentration of 16% or more can be used for power generation. When the gas concentration is lower than 9%, it cannot be used for power generation and can only be released into the atmosphere. , which pollutes the environment and wastes resources

Abstract

The invention discloses a method for safely generating power by the aid of unstable gas sources. A mode that gas is extracted in different sources under the ground, is advanced by a ground generating set and is ignited by the aid of small quantities of diesel oil of the generating set is adopted, the gas with unstable concentration can lead the generating set to run normally, and low-concentration gas can be sufficiently utilized. The method not only can effectively utilize clean energy sources of coal seams, but also realizes good economic and environmental benefits.

Description

technical field [0001] The invention relates to comprehensive utilization of low-concentration gas, especially unstable gas source and low-concentration gas power generation. Background technique [0002] Gas, in the coal industry, refers to coalbed methane or mine gas. Gas is a colorless, tasteless, odorless gas with a relative density of 0.554 to air. Under standard conditions, the density of gas is 0.716kg. The permeability of gas is equal to that of air. It is 1.6 times that of the gas, it is difficult to dissolve in water, it does not support combustion and cannot maintain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can burn or explode. Gas exists in free state and sorption state in coal body or surrounding rock. When the oxygen concentration in the air reaches 10%, the gas concentration is between 5-16%, and it will explode in case of fire. When the concentration is about 30%, it can burn quietly. Th...
