华电喀什热电二期超临界机组烟囱设计高度对环境的影响评价

Evaluation of Chimney Design Height with Supercritical Unit in Second Kashi Thermoelectric of Hua-Power Plant

电厂一直被群众视为排污大户,喀什城区目前正在修建的华电喀什热电二期在满足城区热电需要的同时,不可避免的成为了当地居民关注的排污热点。该研究通过高斯扩散模型和锅炉燃烧经验方程以及烟囱设计高度来模拟评估二期2×350MW超临界机组建成后对周边环境的污染影响,结果表明,烟囱设计210m高度对周边污染质量浓度接近0,因此烟囱设计高度科学合理,高斯扩散模型在模拟计算大气污染影响区域范围方面可以广泛运用。

Power plant has been the masses as the large sewage,under construction of the Huadian Kashi thermoelec-tric second period to meet the needs of urban heat and power,Kashi City inevitably has become sewage focus of theattention of the local residents.By Gaussian diffusion model and boiler combustion empirical equation,and the boilerdesign to simulate the assessment phase 2·350MW supercritical units after the completion on the surrounding envi-ronment pollution. Results show that,210 m chimney design height of pollution of the surrounding mass concentra-tion is close to 0,therefore the chimney design show highly scientific and reasonable.
