　　一、瓦斯介绍

1、 Gas Introduction

　　煤层气在煤矿称为煤矿瓦斯，简称瓦斯根据新的资源评价结果，我国陆上煤层气资源量36.8万亿立方米，与陆上常规天然气资源量（38万亿立方米）相当，仅次于俄罗斯和加拿大。煤层气的主要成分是甲烷，甲烷在空气中的浓度达到5%－16%时，遇明火就会爆炸，这是煤矿瓦斯爆炸事故的根源。

Coalbed methane is called coal mine gas in coal mines, abbreviated as gas. According to new resource evalsuation results, China's onshore coalbed methane resources are 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 coalbed methane is methane. When the concentration of methane in the air reaches 5% -16%, it will explode when exposed to an open flame, which is the root cause of coal mine gas explosion accidents.

　　煤层气不加以利用，直接排放到大气中，其温室效应约为二氧化碳的21倍。煤矿瓦斯发电，既可以有效地解决煤矿瓦斯事故、改善煤矿安全生产条件，又有利于增加洁净能源供应、减少温室气体排放，达到保护生命、保护资源、保护环境的多重目标。

If coalbed methane is not utilized and directly emitted into the atmosphere, its greenhouse effect is about 21 times that of carbon dioxide. Coal mine gas power generation can effectively solve coal mine gas accidents, improve coal mine safety production conditions, increase clean energy supply, reduce greenhouse gas emissions, and achieve multiple goals of protecting life, resources, and the environment.

　　（一）、低浓度瓦斯发电技术

（1） Low concentration gas power generation technology

　　煤矿瓦斯分高浓度瓦斯和低浓度瓦斯，高浓度瓦斯是指瓦斯（甲烷）浓度大于25%的瓦斯，低浓度瓦斯是指瓦斯浓度低于25%的瓦斯。我国60%以上的瓦斯是含甲烷25%以下的低浓度瓦斯，按煤矿安全规程要求，瓦斯浓度在25%以下的就不能贮存和输送。

Coal mine gas is divided into high concentration gas and low concentration gas. High concentration gas refers to gas with a methane concentration greater than 25%, while low concentration gas refers to gas with a methane concentration below 25%. More than 60% of the gas in our country is low concentration gas containing less than 25% methane. According to coal mine safety regulations, gas with a concentration below 25% cannot be stored or transported.

　　低浓度瓦斯发电需要解决2个问题，一是各个煤矿的本身不一样，而且随时都在变化，传统的麻豆性视频网很难;以不变应万变 ，二是低浓度瓦斯的安全输送问题。

Low concentration gas power generation needs to solve two problems. Firstly, each coal mine is different and constantly changing, making traditional generator sets difficult; The second issue is the safe transportation of low concentration gas.

　　济南绿能动力机械有限公司依托胜动和济柴在燃气内燃机领域的技术，研制出的高浓度瓦斯麻豆性视频网，并后继开发出能适用于低浓度瓦斯的中大功率低浓度瓦斯麻豆性视频网，成为掌握低浓度瓦斯麻豆性视频网技术的厂家之一。其中500KW高低浓度瓦斯麻豆性视频网和600KW高低浓度瓦斯麻豆性视频网该机组性能，性价比高。机组采用电控燃气混合器技术，可以自动控制空燃比，以适应瓦斯的浓度变化，适合我国煤矿点多量小的特点，同时，发明了低浓度瓦斯安全输送技术，采用细水雾技术，解决了低浓度瓦斯的地面安全输送问题。

Jinan Green Energy Power Machinery Co., Ltd. has developed a high concentration gas generator set based on the technology of Shengdong and Jichai in the field of gas internal combustion engines, and subsequently developed a medium to high power low concentration gas generator set suitable for low concentration gas, becoming one of the manufacturers that master the technology of low concentration gas generator sets. Among them, the 500KW high and low concentration gas generator set and the 600KW high and low concentration gas generator set have high performance and cost-effectiveness. The unit adopts electric control gas mixer technology, which can automatically control the air-fuel ratio to adapt to changes in gas concentration, suitable for the characteristics of large and small coal mines in China. At the same time, low concentration gas safety transportation technology has been invented, using fine water mist technology to solve the problem of safe transportation of low concentration gas on the ground.

　　（二）、低浓度瓦斯发电基本要求

（2） Basic requirements for low concentration gas power generation

　　首先、按国家煤矿安全管理部门的要求安装了瓦斯抽放系统,并且瓦斯抽放系统须正常运行；其次、瓦斯抽放系统纯瓦斯抽放量在100万m3/年左右，瓦斯浓度在6-25%之间。达到这2个条件就能具备建设瓦斯电站的基础，若建设瓦斯电站就可实现;以利用促抽采、以抽采促安全;的煤矿良性循环发展。

Firstly, a gas drainage system has been installed in accordance with the requirements of the national coal mine safety management department, and the gas drainage system must operate normally; Secondly, the pure gas extraction capacity of the gas extraction system is around 1 million m3/year, and the gas concentration is between 6-25%. If these two conditions are met, the foundation for building a gas power station can be established. If a gas power station is built, it can be achieved; To promote extraction and safety through extraction; The coal mine is developing in a virtuous cycle.
