1. Improve the efficiency of gas power generation

為提高發(fā)電效率，在發(fā)電機(jī)組中可以布置循環(huán)式設(shè)備，以充分利用機(jī)組產(chǎn)生的熱量，且其占地面積小，損耗率降低。對(duì)發(fā)電機(jī)組的增壓室進(jìn)行改進(jìn)，如配合小噴流技術(shù)進(jìn)行瓦斯預(yù)處理、采用二體增封閉提高增壓效果等。不同的瓦斯?jié)舛葧?huì)產(chǎn)生不同的發(fā)電效率，因此，通過(guò)摸索*優(yōu)的搭配得到適合的瓦斯?jié)舛瓤梢愿纳普w發(fā)電效率。

To improve power generation efficiency, circulating equipment can be installed in the generator set to fully utilize the heat generated by the unit, with a small footprint and reduced loss rate. Improvements have been made to the booster chamber of the generator set, such as using small jet technology for gas pretreatment and adopting two body increased sealing to enhance the boosting effect. Different gas concentrations can result in different power generation efficiency. Therefore, obtaining a suitable gas concentration through exploration and optimization can improve the overall power generation efficiency.

2 提高發(fā)電及瓦斯運(yùn)送安全性

2. Improve the safety of power generation and gas transportation

頒布了煤礦用非金屬瓦斯輸送管材安全技術(shù)條件、瓦斯管道輸送自動(dòng)阻爆裝置技術(shù)條件和細(xì)水霧混合安全輸送裝備技術(shù)規(guī)范等10項(xiàng)低濃度瓦斯輸送和利用標(biāo)準(zhǔn)，一方面規(guī)范煤礦安全生產(chǎn)，另一方面也有助于學(xué)者進(jìn)行這些方面的安全性技術(shù)研究。采取加強(qiáng)輸送管道的材料安全性、使用專(zhuān)門(mén)的漏氣監(jiān)測(cè)裝置、合理配置防火阻爆裝置等措施能使安全事故發(fā)生率大大降低。具體如安全設(shè)施安設(shè)段管道應(yīng)選用鋼管，其他輸送管道可選用非金屬管，輸送管道材料需進(jìn)行防腐蝕、防漏氣、防砸壞、防靜電處理。

Ten low concentration gas transportation and utilization standards have been issued, including the safety technical conditions for non-metallic gas transportation pipes used in coal mines, the technical conditions for automatic anti explosion devices for gas pipeline transportation, and the technical specifications for fine water mist mixed safety transportation equipment. These standards not only regulate coal mine safety production, but also help scholars conduct safety technical research in these areas. Measures such as strengthening the material safety of transportation pipelines, using specialized leak monitoring devices, and properly configuring fire and explosion prevention devices can greatly reduce the incidence of safety accidents. Specifically, steel pipes should be used for the installation of safety facilities, while non-metallic pipes can be used for other conveying pipelines. The materials of conveying pipelines should be treated with anti-corrosion, anti leakage, anti smashing, and anti-static measures.

對(duì)發(fā)電機(jī)房和配電室等地配置的照明裝置采用防爆燈具，設(shè)應(yīng)急照明，在變壓器上也要進(jìn)行瓦斯、過(guò)流和速斷等保護(hù)。而瓦斯抽采泵房、輸氣站加壓機(jī)房和低濃度瓦斯管道系統(tǒng)中所選用的電氣設(shè)備、儀表均應(yīng)滿(mǎn)足礦用防爆要求。非防爆設(shè)備和儀表應(yīng)集中安設(shè)到專(zhuān)門(mén)的儀表間（或配電間），并采取相應(yīng)的隔離措施和消防措施。

Explosion proof lamps should be used for the lighting devices installed in the generator room and distribution room, and emergency lighting should be installed. Gas, overcurrent, and quick break protection should also be carried out on the transformer. The electrical equipment and instruments used in the gas extraction pump room, gas transmission station booster room, and low concentration gas pipeline system should all meet the explosion-proof requirements for mining use. Non explosion-proof equipment and instruments should be centrally installed in specialized instrument rooms (or distribution rooms), and corresponding isolation and fire protection measures should be taken.

3 提高瓦斯利用度

3. Improve gas utilization

目前低濃度煤層氣發(fā)電技術(shù)較成熟，發(fā)電機(jī)組運(yùn)行功率一般為700kW。在實(shí)際應(yīng)用中，各個(gè)煤礦的煤層規(guī)模、瓦斯?jié)舛群屯咚沽康惹闆r不同，需要不同功率和利用度高的機(jī)組來(lái)適應(yīng)不同情況?？梢詮耐咚钩椴?、輸送和點(diǎn)燃利用全過(guò)程來(lái)降低瓦斯的損耗，提高可使用瓦斯的數(shù)量?；蛘呤褂弥悄芸刂萍夹g(shù)來(lái)對(duì)瓦斯添加混合氣進(jìn)行精確控制，進(jìn)而提高瓦斯氣體的利用率。對(duì)于通風(fēng)瓦斯，可以經(jīng)過(guò)增壓和濃度濃縮來(lái)進(jìn)行利用。

At present, the low concentration coalbed methane power generation technology is relatively mature, and the operating power of the generator set is generally 700kW. In practical applications, the coal seam scale, gas concentration, and gas volume of each coal mine are different, requiring different power and high utilization units to adapt to different situations. The entire process of gas extraction, transportation, and ignition can be used to reduce gas loss and increase the amount of available gas. Alternatively, intelligent control technology can be used to precisely control the addition of mixed gas to gas, thereby improving the utilization rate of gas. For ventilation gas, it can be utilized through pressurization and concentration concentration.
