In mixed combining method process, the sulphur went along with material and fuel into the system, long term in abundance for serious influence of the curing kiln and evaporator's operation.

In the use of process, the main problem encountered is the proofing problems of PT series fuel system.

A dynamic simulation model of start-up process including fuel pumped section and the dynamic nozzle valve lever, etc. is established for the torpedo thermal power system with pressure adjustment mode.
