Problems solved by technology

[0004] For some small and medium-sized enterprises, if they use a powered gas mixing device for gas mixing operations, the cost will be too high, which will increase the economic cost of the enterprise, and will also increase the failure rate of combustion equipment and reduce the efficiency of production operations. How to study a simple, effective and small air and gas mixing device is very important for the application and promotion of fully premixed combustion, especially the fully premixed static surface combustion system, and this is an urgent problem to be solved at present

Abstract

The invention belongs to the technical field of gas mixture application, in particular to disclose a mandatory all-over three-dimensional gas mixing chamber. The gas mixing chamber comprises a pipeline, an air inlet placed on the pipeline, a gas duct mounted a flange, a gas duct placed inside the gas duct mounted a flange, and a nozzle placed at the end of the gas duct, wherein the nozzle is evenly provided with a plurality of spray orifices, and the connecting section of the gas duct and the nozzle is a curving structure. The mandatory all-over three-dimensional gas mixing chamber has the advantages of being reasonable in design structure, evenly and high efficient in mixing the gas and the air, meeting the burning gas requirement of the mandatory all-over static surface combustion system, low in CO and NOx emissions by evenly mixing and sufficiently burning, realizing the production requirement of energy-saving and emission reduction, effectively prolonging the service of the firing level, reducing the cost on businesses, effectively solving the problem of temper and guarantying the safety of mixed workloads by the increased overpressure air outlet valve.

Description

technical field [0001] The invention belongs to the technical field of gas mixing application, and in particular relates to a forced fully premixed three-dimensional gas mixing chamber, which is suitable for high-efficiency, uniform and safe mixing operations of gas. Background technique [0002] The fully premixed combustion of combustible gas has high combustion efficiency, low CO and NOx emissions, and has significant energy saving and emission reduction characteristics. The more uniform the main air and gas are mixed, the better the combustion state. [0003] Combustion after the air and gas are fully mixed can make the combustion surface evenly heated, which is beneficial to prolong the service life of the expensive combustion surface, and the CO and NOx emissions produced by combustion are lower. For the gas mixing chamber, after the air and gas are mixed according to the stoichiometric ratio, the risk of the air-fuel mixture is much higher than that of pure gas, and i...
