room (1) is to provide heat with hot systems (8) throughout the year by outer defeated steam or hot water piping (9) Source；When having high-pressure and high-temperature steam demand with hot systems (8) throughout the year, boiler steam room (1) passes through high temperature and high pressure steam pipeline (9A) The steam without back pressure apparatus (1A) of boiler generation is provided for it；Richness product High-temperature cooling recirculated water or electric heating pump heating device (25A) is that heat supply network low temperature hot-zone (3) provides heat source through rich cumulative waste heat heat supply pipeline (13B), through richness product heating cooling Low-temperature heat source pipeline (22A) is that steam drive source heat pump device (11) provide low-temperature heat source afterwards, the low temperature after richness product steam heat pump Heat source pipeline (23A) is to be driven by electricity heat pump assembly (12) to provide low-temperature heat source.
