Abstract：Focusing on the issues of poor operation stability and higher outage rate for sintering waste heat power generation system，a mathematical model of multi waste heat boilers paralleling operation power system was constructed based on the theory of probability. The influence of the working status of waste heat boilers on the operation stability of the waste heat power generation system was analyzed. The operation program of waste heat boiler and system steady running，and regulation strategy of steam were put forward. Adopted the in situ steam flow data，the results showed that the operation stability of power generation system would be improved through parallel operation of multiple waste heat boilers. For the sintering waste heat power generation system of four sets of waste heat boilers in parallel shared a generator，the system stable operation probability would exceed 0.98 if three or more waste heat boilers were in normal work. When the system steam was insufficient，the stable operation probability of power generation system could reach above 0.96 through the import of steam from steam network.
