Embodiment Construction

[0016] In the thermal boiler of the utility model, the furnace wall is a hollow water-circulating cavity. The furnace is provided with side-by-side elbows. The inner side of the side-by-side elbows and the furnace wall enclose at least one combustion chamber, and the upper part of the side-by-side elbow leads out from the furnace wall. , The side-by-side elbows are collected in the manifold at the lower part, and both sides of the manifold are opened into the furnace wall. The flame-retardant material is arranged between the side-by-side elbows to separate the upper and side of the combustion chamber from the upper part of the furnace. Fuel input ports are provided on both sides of the furnace wall and the front furnace wall.

[0017] In order to achieve the required combustion temperature in the boiler, only high combustion value fuel can be put in, and the suitable fuel is relatively single. By adopting the multi-combustion chamber structure of the present invention, it is poss...

Abstract

The invention relates to a thermal boiler and belongs to the field of boiler equipment. According to the thermal boiler, the boiler wall is a hollow water circulation inner cavity, bent pipes are arranged in the boiler side by side, at least one combustion chamber is defined by the inner sides of the bent pipes arranged side by side and the boiler wall, the upper portions of the bent pipes arranged side by side extend out from the boiler wall, the lower portions of the bent pipes arranged side by side are converged to a converging pipe, the two sides of the converging pipe communicate with the inner portion of the boiler wall, flame-resistant materials are arranged between the bent pipes arranged side by side, so that the upper portion and the side face of each combustion chamber are partitioned from the upper portion of the inner side of the furnace body. The furnace walls on the two sides and the furnace wall on the front side of each combustion chamber are provided with fuel feeding opening.

Description

Technical field [0001] The invention relates to a thermal boiler, which belongs to boiler equipment. Background technique [0002] In the production of factories, especially those involving chemicals or food, hot water is required as raw material for production or as auxiliary heating. Hot water is usually used for heating in the north. [0003] For thermal boiler structures, there are vertical and horizontal rectangular structures. The opening of the combustion chamber of the common vertical reverse-fired cylindrical thermal boiler faces downwards to achieve the effect of saving coal. However, this kind of structure will result in a higher resistance to the flue gas in the burning state. There are hidden safety hazards in the pressure-bearing use of the furnace wall of the horizontal rectangular reverse-fired boiler. Summary of the invention [0004] The invention relates to a thermal boiler, which solves the problems of relatively large flue gas resistance during combustion ca...
