Gas-based generator set

Gas-based generator set

Coal seam gas in coal mine gas, or gas according to the new resource evaluation results, China's onshore CBM resources of 36.8 trillion cubic meters, equivalent to the onshore conventional natural gas resources (38 trillion cubic meters), second only to Russia and Canada. The main component of the coal seam gas is methane. When the concentration of methane reaches 5% -16% in the air, it explodes in an open fire, which is the source of the coal mine gas explosion.

Gas-based generator set

Gas Introduction

Coal seam gas in coal mine gas, or gas according to the new resource evaluation results, China's onshore CBM resources of 36.8 trillion cubic meters, equivalent to the onshore conventional natural gas resources (38 trillion cubic meters), second only to Russia and Canada. The main component of the coal seam gas is methane. When the concentration of methane reaches 5% -16% in the air, it explodes in an open fire, which is the source of the coal mine gas explosion.

CBM is not utilized and discharged directly into the atmosphere with a greenhouse effect about 21 times that of carbon dioxide. Coal gas power generation in coal mine can not only effectively solve coal gas accidents, improve safe production conditions, but also be conducive to increasing clean energy supply, reducing greenhouse gas emissions, and achieve multiple goals of protecting life, resources and the environment.

Low-concentration gas power generation technology

Coal mine gas is high concentration gas and low concentration gas, high concentration gas is more than 25% gas, low concentration gas is gas concentration less than 25% gas. More than 60% of the gas in China is a low concentration of gas containing less than 25% of methane. According to the requirements of the coal mine safety regulations, the gas concentration of less than 25% cannot be stored and transported.

Low concentration gas power generation needs to solve two problems, one is each coal mine itself is different, and is changing at any time, the traditional generator set is difficult; unchanged to change, the other is the safe delivery of low concentration gas.


Basic requirements for low-concentration gas power generation

First, gas pumping system is installed according to the requirements of National Coal Mine Safety Administration, and the gas pumping system must operate normally; secondly, gas pumping volume of pure gas pumping system is about 1 million m3/ years and gas concentration is between 6-25%. After reaching these two conditions, we can have the foundation of building gas power station, if building gas power station can be realized; to promote extraction and safety; the virtuous cycle development of coal mine.

Division of high and low concentration gas:

Coal mine gas includes high concentration gas and low concentration gas and low concentration gas with less than 25%. More than 60% of the gas in China is a low concentration of gas containing less than 25% of methane. According to the requirements of the coal mine safety regulations, the gas concentration of less than 25% cannot be stored and transported.

Basic requirements for low-concentration gas power generation:

1, has installed the gas pumping system as required by the National Coal Mine Safety Administration, and the gas pumping system must operate normally;

Pure gas pumping volume of the 2, gas pumping system is around 1 million m3/ years, and the gas concentration is between 6-25%.

Unit requirements for gas:

Within 1m from the gas inlet valve of the gas unit

1, gas temperature: ≤ 40 ℃;

2, Gas Pressure 3~20kpa, Pressure Change Rate ≤ 1kpa/min;

3, H2S ≤ 200mg/Nm3

4, For CH4 volume content, high concentration gas generator sets require methane content above 25%, and low concentration gas generator sets require 12% -25% to start normally.

Water content in 5, gas by ≤ 40g/Nm3

6, impurity granularity ≤ 5 μm, impurity content ≤ 30mg/Nm3

If the combustible gas contains high sulfur and ammonia components, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the oil to corrode the internal parts of the unit, while easy to produce sediment, increase wear and corrosion to the engine.

Our factory can configure a single unit unit covering 500kw-800kw according to the actual needs of the customer. For projects with an installed capacity of more than 1MW, we suggest that customers use multiple 500KW units parallel, with the highest comprehensive cost performance. The station is more stable, convenient maintenance and low maintenance cost.
