摘要
为了消除燃煤电站尾部湿烟气与低温空气混合形成的湿烟羽,解决湿烟羽引发的雾霾问题,基于冷凝再热消除烟羽路线,在1台350 MW电站的脱硫塔后搭建实验平台,验证了切线法的可靠性,并利用切线法计算了不同技术路线消除湿烟羽的临界温度。结果表明:现场实验数据与切线法计算数据的相对误差可控制在±10%以内;通过比较不同技术路线消除湿烟羽的临界温度,确定了其热工参数及适用条件,可用于指导燃煤机组烟羽消除系统的实际运行。
In order to eliminate the wet plume formed by the mixing of wet flue gas at the tail of the coal-fired power station and low-temperature air,and to solve the haze problem caused by the wet plume,based on the condensation-reheat route to eliminate plume,the research combining field experiment and tangent method calculation were adopted.The experimental platform was built after desulfurization tower of a 350 MW power station to verify the reliability of the tangent method.Besides,the critical temperature of wet plume elimination of different technical routes was also calculated by the tangent method.Results show that the relative error between the data obtained by experiments and tangent method can be controlled within ±10%.By comparing the critical temperature of wet plume elimination of different technical routes,the thermal parameters and applicable conditions are determined,which can guide the actual operation of plume elimination system in coal-fired units.
