摘　　要：构建了火床炉双侧全截面进风风室和非全侧面进风风室的流动稳定段内流动的封闭方程组。通过理论推导 ,获得了分析解 ,并导出了火床面流量偏差的理论表达式。据此 ,对双侧进风与单侧进风方式下极限流量偏差值所处的位置、流量偏差的极值比进行了比较 ,并分析了风室结构和床层结构对流量偏差的影响。Presented is an enclosed set of equations, which describes the air flow in a flow stabilized section of a stoker boiler dual lateral-side full-section air feed compartment and a full lateral-side air feed compartment. Through a theoretical deduction obtained was an analytical solution along with the deduction of a theoretical expression of the stoker surface flow-rate deviation. On this basis the limiting flow rate deviation location and the flow rate deviation limiting ratio were compared for the following cases: the dual lateral-side air feed mode and the single lateral-side air feed mode. Moreover, an analysis was performed of influence of air compartment construction and stoker grate layer structure on the flow rate deviation.
