摘　　要：对高覆盖率炉拱所在的火床炉炉膛内压差特性进行了试验研究和理论分析，提出了两个设计关系式，并将按此关系式计算得到的结果与试验数据进行了对比、验证，从而为炉拱设计、炉拱改造以及炉膛出口负压的设计和校核提供了简明实用的计算式。Abstract The paper reports on experimental study and theoretical analysis results concerning the differential pressure characteristics inside a grade stoker furnace,featured by double arches with high coverage rate. Two correlating design equations are suggested. Calculation results are verified by relevant test results. These simple and pratical formulas are provided for designing and revamping furnace arches as well as for calculating and checking the negative pressure at the furnace outlet.
