| 中文摘要 | 研究采用20 t/h供暖链条炉,在不改变锅炉主体结构,并保证锅炉出力的前提下,试烧了稻壳成型颗粒。结果表明:随着生物质颗粒掺烧比的增加,排渣烧失量逐渐降低,排烟中CO浓度升高,排烟温度逐渐升高。其中生物质挥发分在对流受热面中燃烧是造成排烟温度升高的主要原因。燃煤链条锅炉改烧生物质颗粒,应该在锅炉前拱或者喉部增加流量小、压头大、速度高的二次风,增强烟气扰动,从而增强挥发分与空气的混合燃烧,达到减排SO2和节约优质烟煤的目的。; Under the conditions that the chain stoker main constructions not to be change and the capacity of the chain stoker not to be reduced,the rice hull particles were utilized in the 20t/h chain stoker.The result shows with the increase of biomass ratio,the loss on ignition(LOI) of stag gradually decreased.The CO concentration and temperature of exhaust gas all gradually increased.The main reason of temperature increase was the combustion of biomass volatile in convective heating surface.It is concluded the small flux,high pressure and big velocity secondary air should be arranged in the front arch region or in the chamber throat in order to enhance the flue gas turbulent and the mix and combustion of air and volatile,so as to decrease the emission of SO2 and save the high quality bituminizes when the coal burning chain stoker combust biomass fuel.; 辽宁省教育厅一般资助项目(20060592) |
