Problems solved by technology

For heating units, there is also the problem of changing working conditions (boundary conditions, such as external scheduling load, ambient temperature, circulating water temperature, etc.), which will lead to changes in the amount of steam extraction and changes in the operating status of the steam turbine. Some cost determination methods cannot accurately calculate the heat consumption cost of cogeneration units.

Embodiment Construction

[0017] Below in conjunction with embodiment the present invention is described in further detail:

[0018] The method for determining the heat consumption cost of cogeneration units based on the working condition analysis method of the present invention comprises the following steps:

[0019] Coal consumption for heat supply of cogeneration units, according to the calorific method, refers to the amount of coal consumed for the same amount of heat. However, for cogeneration units, there is not only heat output, but also heat consumption, so the equivalent amount The amount of coal consumed by heat is deducted from the amount of coal saved in power generation compared with the pure condensate state as the coal consumption of the combined heat and power unit, and the standard coal consumption of the combined heat and power unit is obtained b GJ for:

[0020]

[0021] Among them, η b is boiler efficiency, η p is the pipeline efficiency, b is the pure condensate power generat...

Abstract

The invention discloses a combined heat and power generation unit heat burning cost determination method based on a working condition analysis method. The method comprises the following steps: deducting the coal saving amount of power generation compared with a pure condensation state from the amount of coal with equal heat consumption as the coal consumption amount of the combined heat and powergeneration unit to obtain the heat standard coal consumption bGJ of the combined heat and power generation unit, and the method can accurately determine the heat burning cost of the combined heat andpower generation unit.

Description

technical field [0001] The invention relates to a method for determining the heat consumption cost of a cogeneration unit, in particular to a method for determining the heat consumption cost of a cogeneration unit based on a working condition analysis method. Background technique [0002] Under the background of vigorously promoting energy conservation and emission reduction in the world, building a sustainable development, conservation and environmental protection society, combined heat and power generation is an important technical measure. However, there are certain problems and contradictions in the calculation of heat supply costs, which mainly focus on the analysis of the determination of heat consumption costs of combined heat and power units. The level of fuel consumption directly determines heating and heating. One of the issues that users are most concerned about, the level directly affects the economic interests of all parties. Therefore, it is of great significa...
