Coal firing mode of sectional combustion for coal combustion equipment

Abstract

The present invention is coal burning apparatus in sectional burning mode, and features that the combustion chamber is separated with one partition wall into two parallel combustion chambers, the first combustion chamber and the second combustion chamber, with separate main combustion areas and after combustion areas, and has coal feeding port on one side of the combustion chamber, gasifying a dry distilling area with fuel gas flowing port to communicate the first combustion chamber and the second combustion chamber, fire grates with coal adding layer in the two combustion chambers and flue connected to the end of the second after combustion area. The present invention can burn coal completely in section to save energy source and protect environment.

Description

technical field [0001] The invention relates to a combustion mode of coal-fired equipment, and is particularly suitable for a coal-fired coal-fired equipment segmented combustion mode in which combustion chambers of coal-fired boilers and coal-fired kilns can be clearly segmented, complete combustion, and meet environmental protection standards. Background technique [0002] At present, pollutants such as coal-fired equipment for various boilers, kilns, and heating furnaces, and Ringelmann blackness are all controlled from the tail, which wastes water resources and energy, and produces secondary pollution; in recent years, the occurrence of pure coal gas developed Although the furnace meets environmental protection standards, its wide promotion is limited due to the limitation of coal types and complex structure; in some areas, the promotion of briquette boilers, because loess must be added to the briquettes, if a large number of promotions, loess resources are limited and in...

[0002] At present, pollutants such as coal-fired equipment for various boilers, kilns, and heating furnaces, and Ringelmann blackness are all controlled from the tail, which wastes water resources and energy, and produces secondary pollution; in recent years, the occurrence of pure coal gas developed Although the furnace meets environmental protection standards, its wide promotion is limited due to the limitation of coal types and complex structure; in some areas, the promotion of briquette boilers, because loess must be added to the briquettes, if a large number of promotions, loess resources are limited and increase costs. , the amount of slag discharge increases, and the production cost is high; for this problem, people have started to study from the combustion method of coal combustion, such as secondary combustion, but the combustion method of the above-mentioned combustion equipment also includes secondary combustion. The combustion in the combustion chamber is in the same direction as the coal feeding, so it is easy to appear that when new coal is added from the coal inlet, the carbon particles in the new coal and the combustibles will enter the cold zone before they have time to burn, causing the coal in the combustion chamber to burn. The stage is not very obvious and confused, neither can fully burn, waste energy, but also emit black smoke and pollute the environment
