The difference between a thermal power plant and a heating company

The difference between thermal power plants and heating companies:

Thermal power plants are thermal power plants and waste heat is generated during the electricity production process. This waste heat is used for heating.

The heating company is a department specialized in heating residents.

The power plant not only produces electrical energy, but also uses the steam produced by the turbogenerator to provide heat to users. Compared to. the method of separate production of electricity and thermal energy, saves fuel.

Functional characteristics of thermal power plants:

Taking into account the effect of energy use, the divided production of heat and electricity is completely unreasonable for energy consumption: on the one hand, the process of thermal energy conversion (condensation) power generation by steam generator) will inevitably produce a loss of low quality thermal energy (exhaust steam from the steam turbine releases heat into the cold source, on the other hand, from the high quality thermal energy (steam) heat supplied by the boiler) will be devalued and used for low quality heating. In combined heat and power, the chemical energy of the fuel is converted into high-quality thermal energy, which is first used to generate electricity (high-quality thermal energy), and then uses the low-quality thermal energy that has done work to provide heat to users. This is consistent with the principles of using energy based on quality and overall energy use.

Thus, the characteristic of thermal power plants is that the primary energy is used relatively reasonably,energy is supplied according to its quality, energy is used in stages, and energy is used in the best possible way, so that the overall energy supply system in the region saves energy energy.

Thermal economic indicators:

The thermal economic indicators of thermal power plants are much more complex than those of condensing power plants and heating boiler houses. The first simultaneously produces two products of different shapes and qualities: thermal energy and electrical energy, while the second produces only one product each. Therefore, in addition to the overall thermal economic index, to reflect the thermal economy of a thermal power plant, there must also be sub-indexes for heat and electricity production.

①Total thermal efficiency: the ratio between the production and the energy input of the thermal plant.It reflects the quantitative relationship between the degree of efficient use of fuel in thermal power plants and is therefore a quantitative indicator.

②Thermal energy production rate: the ratio between the thermal energy production of the heating unit and the thermal heat input. It reflects the quality indicators of combined heat and electricity production.

③ Thermal economic indicators in electricity production: the ratio of electricity production of thermal power plants to the share of total heat consumption shared by electricity production, which can be expressed in thermal efficiency of electricity production, heat of electricity production. rate and rate of coal consumption for electricity production.

④ Thermal economic indicators in heating: the ratio of heat supply to thermal power plants and consumptionon total heat shared by the heater, which can be expressed as heating thermal efficiency and heating coal consumption rate.
