Embodiment Construction

[0038] 1) First, use the real-time power generation standard coal consumption and boiler efficiency of the unit calculated in real time by the existing online performance system, and the collected real-time power of the generator to obtain the total heat absorption of the boiler:

[0039] The total heat absorbed by the boiler is:

[0040] Q gl = 100 b e × W × Q dw , bm η b - - - ( 13 )

[0041] In the formula: Q gl ——The real-time total heat absorption of the boiler, MJ / h;

[0042] b e ——the standard coal consumption for power generation calculated by the unit in real time, g / kWh;

[0043] W——generator real-t...

Abstract

The invention discloses a method for calculating coal elements and industrial components in real time, which comprises the following steps of: acquiring the boiler total heat absorption capacity by utilizing the existing calculation results and acquired real-time data; calculating a real-time calorific value of coal as fired by utilizing the real-time coal supply; and calculating elements, moisture and ash of the actual coal as fired in real time by utilizing designed coal elements and industrial components. The coal parameter acquired by the method can also be used for calculating boiler efficiency and coal consumption of thermal power units in real time.

Description

technical field [0001] The invention belongs to the electric power industry, and in particular relates to a method for real-time calculation of coal quality elements and industrial components. The real-time calculation of coal quality element composition involves the content of carbon, hydrogen, oxygen, nitrogen, and sulfur in coal, and the real-time calculation of industrial composition of coal involves the calculation of calorific value, moisture and ash content of coal entering the furnace. It is mainly used for real-time calculation of unit coal consumption, boiler efficiency and coal quality parameters (elements and industrial components). Background technique [0002] Calculation of coal consumption involves real-time calculation of boiler efficiency, turbine heat consumption, pipeline efficiency, and plant power consumption rate. The calculation of boiler efficiency requires real-time acquisition of coal quality parameters (elements and industrial components) of the i...
