Abstract：Aiming at the problems of the large dimensions of a turbine，the limited layout space arises and low heat value of steam，a

reasonable scheme was proposed for utilization of waste heat for steel industries. The scheme is based on a structure of double bypass

steam to backpressure industrial steam turbine. With the new steam turbine，the exhaust heat coule be sufficient exploited，enough power

can supplied to the pump. Lower manufacturing cost，lower construction cost and compact space is needed，thermal water could be gained.

Additional，the technique of manufacturing including material property and strength had been taken into consideration in this scheme. The

results indicate that，this art of backpressure industrial steam turbine might be applied to territory of low grade steam at utilization of

waster heat.

Key words：industrial steam turbine；single stage and back pressure；larger flow and smaller unit type；double bypass steam；

performance and structure.
