Example Embodiment

[0014] The specific technical solutions of the present invention will be further described below in conjunction with embodiments:

[0015] Now for the heating center with a heating area of ​​5 million square meters, the steam boiler uses a 35-ton boiler: 150 tons of coal per day, 500 yuan per ton of coal, daily coal consumption: 150 tons / day×500 yuan / ton=75,000 Yuan / day, of which 50% of the steam loss is used for steam turbine work: 75,000 yuan / day×50%=37,500 yuan / day, the remaining exhausted steam will be supplied to the end of the heating system for heating after the steam-water exchanger heat exchange, and the steam will save 75,000 yuan Yuan / day×50%=37500 Yuan / day.

[0016] Electricity consumption: The heating center of 5 million square meters uses 6000KW / h, and the equipment runs for one day: 6000KW / h×24h=144000KW / day, the electricity price per kilowatt-hour is 0.85 yuan / KW, and the daily electricity consumption is 144000KW / day ×0.85 yuan / KW=122400 yuan / day, if the rotating e...

Abstract

The invention relates to an urban heating method in conformity with the low-carbon energy policy. The method is characterized in that a steam boiler, a turbine and a ground source heat pump constitute integral heating through pipelines, wherein the input water is heated to be steam by the steam boiler and enters into the turbine set through pipelines. The steam drags the turbine set does work, and then the steam exhaust enters into a steam-water heat exchanger for heat exchange, and then the mixing hot water is sent out and is sent to the end heating system. The backwater in the end heating system flows into the condenser of the ground source pump for heat exchange and is heated to 40 DEG C and then sent to the steam boiler, and the power for the compressor of the ground source heat pump is from the power source of the turbine. In the invention, a steam boiler, a turbine and a ground source heat pump are combined. By means of heating the backwater in the system from 35 DEG C to 40 DEG C, the method in the invention can save fire coal by 0.035 tons/m <2>, reduce CO2 emission and SO2 emission by 0.085 tons/m <2> and 0.002 tons/m <2> respectively, as well as save electric charge by **/m <2>.

Description

technical field [0001] The invention relates to an urban heating method, in particular to an urban heating method which is used for urban central heating and conforms to the low-carbon energy policy, and is an improvement on the existing urban central heating method. Background technique [0002] Low-carbon economy: It is an emerging economic form and development model, including a series of new contents such as low-carbon industry, low-carbon energy technology, low-carbon city and low-carbon life. [0003] The existing urban heating forms are roughly divided into several types: thermal power plants, regional boiler rooms, industrial and urban waste heat, geothermal, nuclear energy, heat pumps, solar energy, etc. The first five are concentrated heat sources, and the latter two, gas furnaces, and oil furnaces are independent heat sources. In areas where centralized heat sources are limited, independent heat sources show their own advantages, such as ground source heat pump s...
