Thoughts on 850℃/2s Algorithm Optimization and Temperature Measurement Point Layout of Domestic Waste Incinerator

对某主流焚烧炉技术在主控温度区850℃/2s的算法进行研究,介绍了炉膛烟气量的常用计算方法,以现有荏原焚烧炉的线性插值法作为算法基础,同时引入有效容积算法,并考虑炉温计算起始点、区域平均温度、炉膛结焦情况等因素对公式进行修正,利用焚烧炉出口区域有效容积和锅炉一通道内温度随高度线性变化,优化烟气流速与标高计算,形成炉膛主控温度区850℃/2s的算法,以及基于该优化算法下的温度测点布置方案。

This paper studies the 850℃/2s algorithm of a mainstream incinerator technology in the main controltemperature zone,introduces the common calculation methods of furnace flue gas volume,takes the existing Ebara incinerator linear interpolation method as the algorithm basis,introduces the effective volume algorithm,and modifies the formula considering the starting point of furnace temperature calculation,regional average temperature,furnace coking and other factors,Using the effective volume of the incinerator outlet area and the linear change of the temperature in the first channel of the boiler with the height,the calculation of the flue gas flow rate and elevation is optimized to form the algorithm of 850℃/2s in the furnace main control temperature zone,and the temperature measurement point layout scheme based on the optimization algorithm.
