Problems solved by technology

When the air supply of gas appliances is not normal, there will be unpredictable combustion consequences, such as: physical and chemical emissions exceeding the standard, abnormal extinguishment and deflagration, etc., so that there are many safety measures for gas appliances, but the effect is not obvious
On the other hand, modern gas appliances generally adopt a forced air supply or forced discharge structure. The Achilles heel of this design is poor environmental adaptability and is too sensitive to changes in the atmospheric pressure environment. When abnormal air pressure occurs, the air / gas supply ratio will change. There will be a large change, and the product will appear in an uncertain working condition under normal use conditions. This phenomenon has attracted widespread attention from experts in the gas appliance industry.

Embodiment Construction

[0025] The present invention realizes air\gas constant ratio distribution. The burner includes a combustible gas mixing chamber 15, a pressurized air passage 1 and a gas passage 12 connected with the combustible gas mixing chamber 15, and the air connecting the pressurized air passage 1 and the gas passage 12. Pressure transmitter, gas pressure transmitter. The pressurized air channel 1 is provided with an air pressure pressure inlet 2; the air pressure actuator includes an air positive pressure chamber 3, an air negative pressure chamber 5 and an air pressure differential transmission film 4 arranged between the positive and negative air pressure chambers. The air positive pressure chamber 3 communicates with the pressure sampling port 2 . The gas constant flow device includes a gas positive pressure chamber 10 located at the gas supply end, a gas negative pressure chamber 8 and a gas pressure transmission film 9 arranged between the gas positive and negative pressure chamber...

Abstract

The inventive burner comprises a pressure air passage and a gas passage. On the pressure air passage is disposed an air pressure transducer and in the gas passage are disposed a gas constant-flow device and a gas pressure transducer. The air pressure transducer, the gas pressure transducer and the gas constant-flow device are in the coaxial connection and in the axis direction of the coaxial connection is disposed a regulating spring for changing the air flow into the distance of the compression spring, so as to drive the valve of the gas constant-flow device to open.

Description

technical field [0001] The invention belongs to the field of gas appliances, in particular to a burner structure and a distribution method that realizes the distribution of gas supply and air supply in a fixed ratio when the gas burner is working, and relates to the safety, environmental protection and energy saving of the burner technology. Background technique [0002] The gas appliance widely used in the market at present, generally adopts the method that the gas supply determines the air supply to realize, and this method is based on the premise that the air supply is normal. When the air supply of gas appliances is not normal, unpredictable combustion consequences will occur, such as: physical and chemical emissions exceeding the standard, abnormal extinguishment and deflagration, etc., making gas appliance products have many safety measures, but the effect is not obvious. On the other hand, modern gas appliances generally adopt a forced air supply or forced discharge ...
