Results of calculation show that the influence of different coal quality upon fouling coefficient of the heating surface has comparatively large difference , and affecting more obviously upon the operation performance of boilers 推算结果表明,不同煤质对受热面灰污特性的影响程度相差较大,其对锅炉运行特性的影响比较明显。
In order to improve the peak load regulation performance of boiler and decrease its consumption of oil , the burners were retrofitted by using adjustable horizontal concentrated - diluted pulverized coal burners combustion technology and small oil gun ignator 摘要为提高锅炉低负荷调峰性能和降低锅炉耗油量,利用可调水平浓淡燃烧技术和小油枪点火装置,对燃烧器进行了改造。
Heat efficiency of power station boiler is an important research subject in which carbon loss is an important parameter to reflect combustion performance of boiler , however , there is no favorable means to estimate it definitely 电站锅炉热效率的研究是一个重要的课题。其中,机械未完全燃烧热损失是反映锅炉燃烧工况好坏的一个重要指标,目前却缺乏非常有利的工具和手段来明确判断。
To meet the need of timely and accurate acquaint and analysis of the power plant fuel consumption in the reform of power industry in china , studies in this paper were mainly focused on the following several aspects : online calculation of the thermal economical performance of boiler , steam turbine and heat system was discussed and studied , and the dynamic relationship between real - time unit 本论文从机组的热力特性和负荷因素出发,深入地探究了火电厂的实时负荷与煤耗量的依变关系,通过计算程序得出其变化曲线;然后进一步计算出年、月、日的煤耗量,为燃料部门的购煤提供依据,以便及时做出购煤的计划;同时分析环境温度、煤质变化对机组煤耗量的影响。
