To achieve the above object, the present invention proposes one kind and utilizes integrated gasification combined cycle for power generation system central heating
Method, when reclaiming turbine discharge waste heat and fume afterheat simultaneously, air separation unit produces oxygen, coal in gasification furnace with oxygen
After gas and steam carry out gasification reaction, removed again by purifier after gas cooler cools sulfide in raw gas,
Nitride, dust pollution thing turn into low heat value coal gas in cleaning, and into gas turbine power generation, combustion turbine exhaustion enters waste heat
Boiler produces steam drive steam turbine power generation, and turbine discharge, which enters after condenser exchanges heat with recirculated water, to be condensed, and recirculated water is cold
But cool in tower；Low-pressure steam is extracted from steam turbine, steam is divided into three tunnels, is used to heat heat supply network in steam water heater all the way
Backwater, after reaching assigned temperature, heat-net-pipeline is fed, delivers to heat supply network user；Second road steam enters absorption heat pump, steam turbine
The low level heat energy of steam discharge or recirculated cooling water as absorption heat pump, in the presence of driving heat source, by heat extraction a to high position
In thermal source, the condensation of turbine discharge is realized, and heat recovery has been reclaimed into exhausted spare heat into heat supply network backwater；Steam on 3rd tunnel
Vapour enters another absorption heat pump, and fume afterheat is exchanged heat into cooling water by flue gas condensing heat exchanger, as another absorption
The low level heat energy of heat pump, in the presence of driving heat source, by heat extraction into high-order thermal source, realize flue gas cool-down and flue gas
The condensation of middle vapor, and by heat extraction into heat supply network backwater, reclaimed fume afterheat and the vapor in flue gas.
Beneficial effect：
The embodiments of the invention provide a kind of method using integrated gasification combined cycle for power generation system central heating, tool
There is cleaning, efficiently, technology maturation, recovery waste heat amount is big, has recovery condensed water concurrently, and the spy of smoke evacuation reclaimed water evaporation loss is greatly decreased
Point.
Brief description of the drawings
Fig. 1 is the flow chart of the embodiment of the present invention.
Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
Embodiment 1
Referring to shown in Fig. 1, a kind of method that the present embodiment utilizes integrated gasification combined cycle for power generation system central heating,
The integrated coal gasification combined cycle system of clean and effective is combined with extracted steam from turbine heat supply, and driven with extracted steam from turbine
Absorption heat pump, turbine discharge waste heat and fume afterheat are reclaimed, is concentrated using extracted steam from turbine heat with recovery waste heat
Heat supply, its central heating method are：Air separation unit produces oxygen, coal after gasification furnace and oxygen and steam carry out gasification reaction,
Turned into again by pollutants such as the sulfide in purifier removing raw gas, nitride, dust after gas cooler cools
Low heat value coal gas in cleaning, into gas turbine power generation, combustion turbine exhaustion enters waste heat boiler and produces steam drive steamer
Machine is generated electricity, and turbine discharge, which enters after condenser exchanges heat with recirculated water, to be condensed, and recirculated water cools in cooling tower；From steam turbine
Low-pressure steam is extracted, steam is divided into three tunnels, is used to heat heat supply network backwater in steam water heater all the way, after reaching assigned temperature,
Heat-net-pipeline is fed, delivers to heat supply network user；Second road steam enters absorption heat pump I, and turbine discharge is as absorption heat pump I
Low level heat energy, in the presence of driving heat source, by heat extraction into high-order thermal source, realize the condensation of turbine discharge, and
By heat recovery into heat supply network backwater, exhausted spare heat has been reclaimed；3rd road steam enters absorption heat pump II, as absorption type heat
Pump II driving source, fume afterheat are exchanged heat into cooling water by flue gas condensing heat exchanger, the low level as absorption heat pump II
Thermal source, in the presence of driving heat source, by heat extraction into high-order thermal source, realize vapor in flue gas cool-down and flue gas
Condensation, and by heat extraction into heat supply network backwater, reclaimed fume afterheat and the vapor in flue gas.Flue gas heat-exchange unit can be straight
It can be surface-type heat exchanger to connect contact, and direct-contact heat exchanger has gas washing effect, pollutant in flue gas is reached
The effect of removing again；Further, since wash conditions be present, N oxidations can be carried out in direct-contact heat exchanger, formation is easy to
The high price N ions removed in water.Absorption heat pump I and absorption heat pump II is seen as being arranged in parallel from heat supply network backwater side, i.e., hot
