Problems solved by technology

[0004] According to the inventor's understanding, the current urban central heating mainly includes several heating methods such as large-scale cogeneration units (generally above 200MW), small-scale cogeneration units (generally below 50MW), small coal-fired boilers, and small coal-fired boilers. Boilers and small cogeneration units have low efficiency, while large cogeneration units have high thermal efficiency. Using high-efficiency cogeneration units to re

Abstract

The invention provides a coal pressure reduction calculation method and a coal pressure reduction calculation system for heat supply substitution of a combined heat and power generation unit, which divide coal consumption of the combined heat and power generation unit into heat supply coal consumption and power generation coal consumption on the premise of ensuring balance of total heat and totalelectric quantity of a whole area. The heat supply and power generation coal consumption of large and small combined heat and power generation units is calculated respectively, then the total coal pressure reduction after full-area heat supply substitution is calculated, operation is easy, and the calculation result is accurate.

Description

technical field [0001] The disclosure belongs to the technical field of energy calculation, and in particular relates to a calculation method and system for coal-fired pressure reduction for heating replacement of cogeneration units. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Coal consumption for heating in winter accounts for a very large proportion of total coal consumption, and coal is the main energy source for heating in some areas. [0004] According to the inventor's understanding, the current urban central heating mainly includes several heating methods such as large-scale cogeneration units (generally above 200MW), small-scale cogeneration units (generally below 50MW), small coal-fired boilers, and small coal-fired boilers. Boilers and small cogeneration units have low efficiency, while large cogeneration units have high th...
