Problems solved by technology

[0002] At present, most of the small coal-fired boilers adopt the water tube boiler structure. The advantage of the water tube boiler is that the thermal efficiency is higher than that of the fire tube boiler. The disadvantage is that the furnace body is relatively large, there are many consumables, the manufacturing process is complicated, and it is not easy to maintain.

Embodiment Construction

[0010] Example. As shown in accompanying drawing 1, the briquette (such as square briquette) coal-fired boiler of N-shaped fire tube, constitutes and comprises furnace body 1 in existing fire tube boiler structure, cover 4, chimney 12, ash chamber 7 , the fire pipe 2, the connecting head 3 arranged at the upper end and the lower end of the fire pipe 2, the connecting head 3 is preferably an arc-shaped connecting head, and a water storage bin is formed between the upper and lower heads; it also includes a briquette combustion chamber 5 , coal pushing device 9, briquette gas guide arch 11; then comprise pulverized coal combustion chamber 6, furnace inner dust shield 8, cyclone powder machine 10 (referring to accompanying drawing 2) for pulverized coal boiler. Regardless of whether it is a shaped coal boiler or a pulverized coal boiler, the characteristic of the N-shaped fire tube coal-fired boiler is that the fire tube 2 is an N-shaped fire tube composed of three or more section...

Abstract

The invention discloses a coal fired boiler with an N shaped fire tube. The boiler includes a boiler body 1, a closure head 4, a chimney 12, a clinker chamber 7, a fire tube 2, and a connection seal head 3 arranged at upper end and lower end of the fire tube 2. The boiler is characterized in that said fire tube 2 is an N shaped fire tube consisting of tubes of three segments or above. The invention is provided with a small boiler body and high thermal efficiency.

Description

technical field [0001] The invention relates to a coal-fired boiler, in particular to the structure of a fire-tube type coal-fired boiler. Background technique [0002] At present, most of the small coal-fired boilers adopt the water tube boiler structure. The advantage of the water tube boiler is that the thermal efficiency is higher than that of the fire tube boiler. The disadvantage is that the furnace body is relatively large, there are many consumables, the manufacturing process is complicated, and it is not easy to maintain. Contents of the invention [0003] The object of the present invention is to provide a coal-fired boiler with N-shaped fire tubes. This kind of boiler not only has a small furnace body, less consumables, is easy to manufacture and maintain, but also has a higher thermal efficiency than a water tube boiler. [0004] The present invention is achieved like this. A coal-fired boiler with N-shaped fire tubes is composed of a furnace body 1, a cover ...
