Abstract:

This paper raised a heat supply steam waste pressure recycling system that utilize heat supply extraction waste pressure for backpressure turbine power generating, and supply steam, exhausted by backpressure turbine, to heat network heater. This system efficiently used heat supply steam extraction, increased heat supply unit generating capacity, lowered unit service power utilization. Economic benefit is significant.

Key words:

heat supply unit, back pressure steam turbine, ladderform energy utilization, waste pressure utilization
