Abstract

The possibility of increasing the reactivity of low grade Kansk-Achinsk brown coal 2 BR from the Irsha-Borodino deposit due to mechanically activated micronizing by means of special mill disintegrators has been shown on the 5-MW experimental firing stand at the Institute of Thermophysics SB RAS (IT). This coal is used in the coal-fired PK-38 boiler of station 2B of the Krasnoyarsk State District Power Station-2 (SDPS-2). The experimental studies to ensure ignition and achievement of stable autothermal coal combustion have yielded the minimum operation time of the gas ignition device; to determine the effect of temperature on the ignition and combustion, the temperature of the burner muffle wall was controlled. In accordance with the experimental data on burning the coal with increased reactivity and the economic efficiency evaluation, the coal can be recommended for replacement of highly reactive fuel oil for ignition and lighting of the boiler considered.

机械活化微粉煤代替燃油的燃煤锅炉点火和照明

摘要

在热物理研究所的5兆瓦实验燃烧台上已显示出由于通过特殊粉碎机进行机械活化的微粉化处理而使Irsha-Borodino矿床产生的低品位Kansk-Achinsk褐煤2 BR的反应性增加的可能性RAS（IT）。该煤用于克拉斯诺亚尔斯克州2号电站（SDPS-2）2B号站的燃煤PK-38锅炉。确保点火并实现稳定的自热煤燃烧的实验研究已使燃气点火装置的运行时间最短。为了确定温度对点火和燃烧的影响，控制了燃烧器马弗炉壁的温度。根据有关提高反应性燃烧煤炭的实验数据和经济效益评估，
