Combusting device composite heating element with infra red radiation function used on gas-fired boiler

Abstract

This invention provides a sort of complex heating unit having the function of infrared radiation of the burner that it is characterized in that simple technique, high standardization degree, no weathering, no breach, and blaze combustion stably and no backfire phenomenon happened in the gas stove. This complex heating unit consists ofthe double-tier material or the several double-tier material, There is the honeycomb body which can forbear the high temperature and the cauterization in the substrate, there is the wire reticulated body or the fibrin body which can forbear the high temperature and the cauterization in the super stratum. The wire reticulated body of the super stratum in this invention can stabilize the flow and prevent this phenomenon in that backfire. The wire reticulated body of the super stratum resists the wind greatly, burn much more steadily and its firepower is stronger, also this invention can obtain holistic slippage with the fitting surface contacts hermetically with the air drain of the burner, and can be use with no jointing.

Description

Technical field: [0001] The invention relates to the technical field of gas furnaces, in particular to a burner composite heating element with infrared radiation function used in gas furnaces. Background technique: [0002] As we all know, the existing atmospheric gas stoves that rely on secondary air for supplementary combustion and convection heating have many defects such as low thermal efficiency, incomplete combustion, and high emissions of NXO compounds and CO. In recent years, in order to improve the thermal efficiency of the stove, people reduce harmful gases emissions and environmental pollution, and invented a fully premixed infrared radiation heating gas cooker. Practice has proved that the fully premixed flameless combustion infrared radiation heating gas cooker can completely solve the above problems, but the infrared ceramic radiation heating plate on the infrared gas cooker burner has a common problem for a long time. The stability of the matrix material is p...

Problems solved by technology

[0002] As we all know, the existing atmospheric gas stoves that rely on secondary air for supplementary combustion and convection heating have many defects such as low thermal efficiency, incomplete combustion, and high emissions of NXO compounds and CO. In recent years, in order to improve the thermal efficiency of the stove, people reduce harmful gases emissions and environmental pollution, and invented a fully premixed gas cooker heated by infrared radiation

Practice has proved that the fully premixed flameless combustion infrared radiation heating gas cooker can completely solve the above problems, but the infrared ceramic radiation heating plate on the infrared gas cooker burner has a common problem for a long time. The stability of the matrix material is poor, and the process standardization is extremely difficult. The sealing performance of the ceramic sheet and the metal shell is poor. At the same time, after the infrared ceramic plate is made into a cooker, the infrared ceramic plate often cracks and weathers during the use of the cooker. However, once the infrared ceramic plate bursts and weathers, the cooker will flash back, and once a cooker tempers, it will cause the possibility of burning the entire cooker, and once the cooker burns out, it will cause greater danger.

Therefore, although the technical indicators of infrared gas cookers, such as energy saving, high efficiency, environmental protection, and non-smoking pot, are stronger than atmospheric cookers, and the testing by authoritative departments is recognized as good, the above problems cannot be fundamentally solved for a long time, restricting infrared gas cooker products. development and promotion of
