Combustion furnace and furnace body structure

Abstract

Disclosed is a furnace body structure. The furnace body is divided into a plurality of portions through a vertical division structure; every two adjacent portions are connected through a connecting part; the furnace body is provided with a chimney opening, a fire outlet, a feeding inlet and an ash hopper or an air inlet; the inner wall of the furnace body is provided with a separation plate which is formed in a one-step mode and is roughly horizontal or the inner wall of the furnace body is provided with a supporting block which is used for supporting the separation plate which is roughly horizontal. The invention also provides a combustion furnace with the furnace body structure. The separation plate is arranged in the furnace body; the lower portion space of the furnace body is isolated into an ash chamber through the separation plate; a combustion chamber is located above the separation plate which is arranged in the furnace body; an inner chamber of the combustion chamber is communicated with the ash chamber; a channel for the flus gas to pass through is formed between the top of the combustion chamber and the inner side of the top of the furnace body; the furnace body is provided with a feeding channel and a chimney connection pipe. According to the combustion furnace and the furnace body structure, the vertical division structure is adopted and accordingly the stripping of every structural portion in the furnace body is facilitated, the one-step forming through a die is facilitated, the forming accuracy is high, and the installation efficiency of the integral combustion furnace is greatly improved.

Description

technical field [0001] The invention relates to the field of civil combustion furnaces, in particular to a combustion furnace using firewood, bellflower or coal as fuel and a furnace body structure. Background technique [0002] Existing combustion furnaces, such as more energy-saving return air furnaces, gasifiers or return air gasification furnaces, are usually welded by bending steel plates, or cast in sections from top to bottom, and then welded or bolted. become. The existing problem is that the processing cost is high, especially the welding process cost is high, and the site environment is poor, the labor intensity of workers is high, and the production efficiency is low. [0003] The material of the existing furnace body is mostly steel plate and cast iron. The thermal conductivity of the furnace body is poor, and the problem of uneven heat distribution on the furnace body often occurs. For example, the temperature difference between the position near the chimney an...

Problems solved by technology

The problem is that the processing cost is high, especially the welding process cost is high, and the site environment is poor, the labor intensity of the workers is high, and the production efficiency is low

[0003] The material of the existing furnace body is mostly steel plate and cast iron. The thermal conductivity of the furnace body is poor, and the problem of uneven heat distribution on the furnace body often occurs. For example, the temperature difference between the position near the chimney and the position near the feeding channel is 30- 50 degrees

In order to improve the heating effect, it is necessary to set up a turnback structure in the flue, which increases the wind resistance and affects the combustion efficiency
