分析了锅炉吸热量在过热、再热和蒸发受热面之间的合理分配份额 ,计算锅炉受热面沾污情况对其它受热面传热的影响。依据“能量损耗最小”的原则 ,示例说明单个受热面最佳吹灰周期计算 ,给出合理确定吹灰方案的方法步骤和在吹灰过程中保持蒸汽参数的方法
The rational distribution share of heat absorption of boiler in superheating, reheating and evaporating heating surface is analyzed, and the influence of boiler heating surface contamination on the heat transfer of other heating surfaces is calculated. Based on the principle of “least energy loss”, the example shows the calculation of the optimum soot blowing cycle for a single heated surface, the method steps for judging the soot blowing program reasonably, and the method for maintaining the steam parameters during soot blowing
