High power gas catalytic burner

Abstract

A catalytic burner of large-power fuel gas type is prepared for connecting gas inlet end of gas transmission pipe to one end of T-joint on pipe, connecting the other two ends in form of 90 degree elbow of T-joint to mixed gas channel, arranging fluid rectifier separately at inlet and outlet of mixed gas channel, connecting one set of catalyst carrier porous module set in frame separately to each of double-surface at burner cavity, packing high-temperature resisting insulation material at peripheral gap of said module and extending temperature transducer into said module through a temperature transducer entrance set on external wall of burner cavity.

Description

(1) Technical field [0001] The invention relates to a burner using gas as fuel, in particular to a catalytic burner. (two), background technology [0002] Catalytic combustion uses a catalyst to control the combustion chemical reaction process and release heat under certain conditions, but the catalyst itself is not consumed. Catalytic combustion can reduce activation energy, accelerate necessary chemical reactions, and minimize harmful or unnecessary chemical reactions. At present, the catalytic combustion of natural gas has achieved a combustion efficiency greater than 99.99%, while the harmful substances NOx, CO, and HC emitted by the flue gas are all less than 10×10 -6 , it is very obvious that the combustion efficiency of catalytic combustion is extremely high, and the pollutants are effectively controlled while burning, so catalytic combustion is an ideal and environmentally friendly combustion method. [0003] It is well known that the greenhouse effect of methane e...

Problems solved by technology

On the other hand, the flow rate distribution of the fully premixed gas through the catalyst carrier must be uniform, otherwise the local temperature will be too high, resulting in local catalyst deactivation and the entire catalytic burner cannot work normally

Because the catalyst is limited by the high temperature limit, the combustion intensity per unit area of ​​the catalyst carrier of the catalytic burner cannot be too large. To increase the combustion power, the combustion area can only be increased, but the increase in the combustion area of ​​the catalyst carrier will inevitably lead to uniform preheating of the catalyst carrier. Thermal difficulties make the structure of high-power catalytic burners complex and bulky, making it difficult for industrial applications
