Online coal quality monitoring optimization operation method

Abstract

The invention discloses an online coal quality monitoring optimization operation method. A system comprises an intelligent online coal quality analyzer, a coal scraping plate action controller, a coal conveying belt, a coal scraping plate and a coal bunker; the intelligent online coal quality analyzer is installed on the coal conveying belt; the intelligent on-line coal quality analyzer is in communication connection with the coal scraping plate action controller; the coal scraping plate is arranged above the coal conveying belt; the coal scraping plate is in communication connection with the coal scraping plate action controller; and the coal bunker is arranged below the coal conveying belt, and the coal bunker is located below the coal scraping plate. Real-time analysis data of an online coal quality analyzer are fully mined based on an existing intelligent online coal quality analyzer, intelligent control is achieved for different coal qualities according to experience in actual operation, the combustion efficiency of a boiler is effectively improved, meanwhile, deep peak regulation of the boiler is improved, and preventive control over atmospheric pollutants can be effectively achieved.

Description

technical field [0001] The invention relates to an online coal quality monitoring and optimization operation method, which is mainly aimed at coal-fired direct blowing units for thermal power generation. Background technique [0002] At present, coal-fired units are affected by new energy power generation, and most units must adopt an optimized operation mode to meet the peak-shaving demand of the power grid. Changes in the operation mode must give full play to the coal quality online monitoring system of coal-fired units, and improve the flexibility of coal-fired units in terms of fuel. [0003] At present, the large-scale promotion of deep peak-shaving technology of coal-fired units requires that coal-fired units must fully exploit the analysis capabilities of online coal quality monitoring facilities, play the role of real-time monitoring, and improve the coordinated coal feed control of coal-fired units, so as to It is suitable for the deep peak regulation of coal-fired...
