1 提高瓦斯發(fā)電效率

1. Improve the efficiency of gas power generation

為提高發(fā)電效率，在發(fā)電機組中可以布置循環(huán)式設備，以充分利用機組產生的熱量，且其占地面積小，損耗率降低。對發(fā)電機組的增壓室進行改進，如配合小噴流技術進行瓦斯預處理、采用二體增封閉提高增壓效果等。不同的瓦斯?jié)舛葧a生不同的發(fā)電效率，因此，通過摸索*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條件、瓦斯管道輸送自動阻爆裝置技術條件和細水霧混合安全輸送裝備技術規(guī)范等10項低濃度瓦斯輸送和利用標準，一方面規(guī)范煤礦安全生產，另一方面也有助于學者進行這些方面的安全性技術研究。采取加強輸送管道的材料安全性、使用專門的漏氣監(jiān)測裝置、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。具體如安全設施安設段管道應選用鋼管，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.

對發(fā)電機房和配電室等地配置的照明裝置采用防爆燈具，設應急照明，在變壓器上也要進行瓦斯、過流和速斷等保護。而瓦斯抽采泵房、輸氣站加壓機房和低濃度瓦斯管道系統中所選用的電氣設備、儀表均應滿足礦用防爆要求。非防爆設備和儀表應集中安設到專門的儀表間（或配電間），并采取相應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)電技術較成熟，發(fā)電機組運行功率一般為700kW。在實際應用中，各個煤礦的煤層規(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組來適應不同情況。可以從瓦斯抽采、輸送和點燃利用全過程來降低瓦斯的損耗，提高可使用瓦斯的數量?；蛘呤褂弥悄芸刂萍夹g來對瓦斯添加混合氣進行精確控制，進而提高瓦斯氣體的利用率。對于通風瓦斯，可以經過增壓和濃度濃縮來進行利用。

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.
