甲醇弛放气用于掺烧燃气锅炉的实践

Practice of Blending the Methanol Purge Gas into the Fuel for Gas-fired Boilers

介绍了山西焦化股份有限公司甲醇生产中甲醇弛放气的利用情况,对弛放气用于掺烧燃气锅炉的理论燃烧温度和过量空气系数进行了计算和分析;并介绍了弛放气用于掺烧燃气锅炉时弛放气接出位置的确定、所采取的输送方式、减压方式等技术措施,实践证明甲醇弛放气掺烧对燃气锅炉系统基本没有不良影响,具有较好的社会和经济效益。

The utilization of the methanol purge gas was introduced, and the theoretical combustion temperature and the excess air factor of the purge gas as a blend for the gas-fired boilers were calculated and analyzed. The method of delivering the purge gas to the boilers, and the pressure reduction of the gas, etc. were put forward. Practice proved that there was practically no adverse impact on the gas-fired boilers when the methanol purge gas was blended into the fuel gas, yet quite good social and economic benefits could be obtained.
