君发科技煤矿瓦斯无焰氧化技术 助力余吾南风井抽采瓦斯近零排放

Core Viewpoint - The successful operation of the low-concentration gas heat recovery and power generation project at the Shanxi Lu'an Chemical Group's Yuwu Coal Mine marks a significant step towards achieving the national "dual carbon" strategy, utilizing previously wasted low-concentration gas to provide clean energy for the coal mine [1][5]. Group 1: Project Overview - The project, designed by Beijing Junfa Technology Group and operated by Shanxi Jinyupeng Technology Co., aims to convert 2%-6% ultra-low concentration gas into clean thermal energy, achieving near-zero emissions in gas extraction [1][5]. - The first phase included the construction of a 11.2MW gas power plant, which utilized all methane with a concentration above 9%, while the second phase focuses on utilizing the remaining 25-30Nm³ of ultra-low concentration gas for heating [2][4]. Group 2: Environmental Impact - The project is expected to destroy 11.52 million standard cubic meters of methane annually, equivalent to a reduction of 230,000 tons of CO₂ emissions [5]. - The low-nitrogen heat recovery oxidation system achieves a methane destruction rate of over 99%, with exhaust emissions of NOx maintained below 10mg/Nm³, meeting national clean emission standards [6]. Group 3: Future Developments - The third phase will add a 20t/h waste heat boiler and a 3MW power generation system, aiming to fully utilize extracted gas and generate 12 million kWh of green electricity annually [7]. - Upon completion, the project will replace 14,000 tons of coal, eliminate dust emissions by 200 tons, and achieve 100% self-sufficiency in heating energy for the mine [9]. Group 4: Economic and Social Benefits - The project is projected to create over 30 jobs in operations management, technology research and development, and intelligent operations, contributing to the transformation of resource-based cities [10]. - The implementation of Junfa's innovative technology is seen as a model for green transformation in coal mining, with plans to replicate this model in other mining areas [10].
