Problems solved by technology

At present, the sulfur content of the furnace coal in the power plant is determined by real-time measurement and manual input of laboratory data. Real-time measurement has radiation sources, and the measurement accuracy is not high. Manual input of laboratory data cannot reflect the operating status of the unit in real time.

Abstract

The invention provides a method for calculating a coal quality sulfur component in real time. According to the real-time concentration of SO2 at a desulfuration adsorption tower inlet, the dry smoke volume of an air preheater outlet, the air preheater outlet oxygen amount and the oxygen amount at the desulfuration adsorption tower inlet, and the mass percentage of a boiler entering coal sulfur component is calculated in real time. According to data collected by a unit at present and a performance calculation result, the boiler entering coal sulfur content of a power plant is calculated in real time. The real-time coal quality sulfur mass percentage requirement used for coal sulfur content and boiler efficiency calculation can be satisfied. Manual input interference is effectively avoided, and the objectiveness and the reliability of data can be guaranteed.

Description

【Technical field】 [0001] The invention belongs to the electric power industry and relates to a method for real-time calculation of a coal-fired unit, in particular to the calculation of the sulfur content of coal fed into a furnace in a power plant, which can be applied to real-time calculation of boiler efficiency and real-time calculation of coal consumption of a unit. 【Background technique】 [0002] Sulfur dioxide in boiler flue gas has a certain impact on the safety and normal operation of boiler heating surface and desulfurization system. At present, the sulfur content of the furnace coal in the power plant is determined by real-time measurement and manual input of laboratory data. Real-time measurement has radiation sources, and the measurement accuracy is not high. Manual input of laboratory data cannot reflect the operating status of the unit in real time. 【Content of invention】 [0003] The purpose of the present invention is to provide a method for real-time calc...
