Problems solved by technology
[0002] At present, many chemical companies produce a lot of industrial waste gas with low calorific value during the production process. Due to the low calorific value of the waste gas (combustible value ≤ 20%), normal boiler burners cannot burn, and the waste gas is discharged into the atmosphere, causing pollution
At the same time, it also causes the resource loss of waste gas utilization

Embodiment Construction
[0010] A waste gas inlet (4) is connected to the upper part of the boiler body (3), and the waste gas inlet (4) is arranged at the front part of the boiler body (3). Boiler furnace wall (8) and fixed fire grate (7) are basically the same as row boiler shell type boiler, difference is that refractory concrete (9) is built by laying bricks or stones at the bottom of boiler (10). The waste gas inlet (4) is connected with the fixed fire grate (7). The upper solenoid valve (1) is connected to the exhaust outlet (2) for exhaust. The boiler body (3) is cylindrical, and the bottom is provided with refractory concrete (9) connected to the bottom of the boiler (10). The lower solenoid valve (5) is arranged at the exhaust gas outlet (6) so as to facilitate exhaust.

The invention relates to a novel low calorific value waste gas combustion steam boiler. A waste gas inlet is connected to the upper part of a boiler body and positioned at the front part of the boiler body; and a boiler wall, and a fixed fire grate of the steam boiler is basically consistent with a shell-type boiler, the difference lies in that refractory concrete is built at the bottom of the boiler; the waste inlet is connected with the fixed fire grate; an upper electromagnetic valve is connected with a waste gas outlet for exhausting gases; the boiler body takes the shape of a cylinder, and the refractory concrete placed at the bottom of the boiler is connected with the boiler bottom; and a lower electromagnetic valve is positioned at the waste gas outlet so as to be convenient for gas exhaust. The invention has the beneficial effects of being suitable for combustion of all industrial waste gases with low calorific values and simultaneously being good for protecting the environment and reducing the pollution and the cost, thereby achieving the aims of environmental protection and energy saving.
Description
technical field [0001] The invention relates to a steam boiler, in particular to a new type of low calorific value exhaust gas steam boiler. It belongs to the technical field of combustion equipment boilers. technical background [0002] At present, many chemical companies produce a lot of industrial waste gas with low calorific value in the production process. Due to the low calorific value of the waste gas (combustible value ≤ 20%), normal boiler burners cannot burn, and the waste gas is discharged into the atmosphere, causing polluted. At the same time, it also causes the resource loss of waste gas utilization. Contents of the invention [0003] The purpose of the present invention is to provide a new type of low calorific value waste gas steam boiler which is suitable for the combustion of low calorific value industrial waste gas, and at the same time is beneficial to environmental protection and reduces pollution. [0004] The technical solution adopted to solve th...
