Problems solved by technology

As the market price of thermal coal continues to rise, some coal types that are not suitable for boiler combustion must also be purchased, resulting in a large difference between the incoming coal type and the boiler design coal type
To ensure the thermal efficiency of the boiler under the existing conditions, it is necessary to match the coal combustion characteristics with the design parameters of the boiler. It is difficult to achieve the best effect if the coal quality is too high or too low.
[0003] The method of coal blending is single and fuzzy, not flexible enough, so there is insufficient understanding of the characteristics of coal quality and the adaptability of the coal to be blended with the boiler equipment, resulting in boiler fire extinguishing and deflagration during the operation of the boiler when the coal quality of the incoming coal changes greatly , blasting of the pulverizing system, serious corrosion and wear of the heating surface, and excessive discharge of pollutants have seriously affected the safe and economical operation of the boiler

Abstract

The invention provides a coal combustion management method and device and relates to the technical field of fuel management. The method comprises the steps that basic data corresponding to each kind of coal of different kinds of coal of a boiler are acquired, the coal parameters of each kind of coal are acquired according to the basic data of each kind of coal, and the proportion of the differentkinds of coal is determined according to the coal parameters of each kind of coal and default boiler parameters. By the adoption of the coal combustion management method and device, accurate coal blending can be realized, coal is saved, and the safety of the boiler is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of fuel management, in particular to a method and device for coal combustion management. Background technique [0002] The selection of boilers in thermal power plants has corresponding design coal types. When the coal quality exceeds the set adaptation range, it will have a great impact on the safety and economy of the boiler. As the market price of thermal coal continues to rise, some coal types that are not suitable for boiler combustion must also be purchased, resulting in a large difference between the incoming coal type and the boiler design coal type. To ensure the thermal efficiency of the boiler under the existing conditions, it is necessary to match the coal-fired characteristics with the design parameters of the boiler. It is difficult to achieve the best results if the coal quality is too high or too low. [0003] The coal blending method is single and vague, and not flexible enough. Therefore,...
