Description
Technical field
The present invention relates to high temperature air combustion technology field, more particularly to a kind of burner and storage for heat-storage type burner
Hot type burner.
Background technology
The operation principle of heat-storage type burner is that burner occurs in pairs, and such as when burner A big fire is burnt, burner B big fire is put out
Go out and flame combustion kept burning day and night, the combustion air passage of burner B serves as flue, and the waste heat in flue gas heats the heat storage of burner B
To certain temperature, and the temperature of flue gas itself is reduced, after the time set in advance, change the flowing of air-flow in tube body
Direction, combustion air and combustion gas first pass around the higher heat storage heating of temperature, and then burner B big fire is burnt, and burner A big fire is put out
Go out and flame combustion kept burning day and night, the combustion air passage of burner A serve as flue, can so preheat combustion air, realize in flue gas
Waste heat compared with the recycling of limits, be also beneficial to the abundant progress of burning.
In order to ensure the security of combustion system work, the small fire of two burners must keep state kept burning day and night, and by examining fire
Whether the small fire of two burners of electrode detection is in combustion state.But the fire inspection signal of the heat-storage type burner in correlation technique
It is unstable, so lead to not to judge two burners whether holding state kept burning day and night, there are security risk, thus how to strengthen fiery inspection

For example, in the example of fig. 1, two burners 10 are burner 10 according to the above embodiment of the present invention.Two burnings
Mouth 10 is respectively burner A and burner B.
When burner A big fire is burnt, burner B big fire is extinguished, and the flame combustion kept burning day and night of burner B, the combustion air of burner B leads to
Road 61 serves as flue, and the flue gas that burner A big fire burning produces can be discharged from the combustion air passage 61 of burner B.Wherein, burner
During the combustion air passage 61 for the flue gas flow direction burner B that A big fire burning produces, the baffle part 9 on burner B can stop incoming cigarette
The air-flow of gas, avoids air-flow from directly impacting the flame kept burning day and night of burner B, efficiently reduces the air-flow in tube body 20 to burner B's
The influence of flame kept burning day and night, improves the stability of the flame kept burning day and night of burner B, so as to improve the stability of fire inspection signal, and protects
Function of the flame kept burning day and night of burner B as incendiary source is demonstrate,proved.
When burner B big fire is burnt, burner A big fire is extinguished, and the flame combustion kept burning day and night of burner A, the combustion air of burner A leads to
Road 61 serves as flue, and the flue gas that burner B big fire burning produces can be discharged from the combustion air passage 61 of burner A.Wherein, burner
During the combustion air passage 61 for the flue gas flow direction burner A that B big fire burning produces, the baffle part 9 on burner A can stop incoming cigarette
The air-flow of gas, avoids air-flow from directly impacting the flame kept burning day and night of burner A, efficiently reduces the air-flow in tube body 20 to burner A's
The influence of flame kept burning day and night, improves the stability of the flame kept burning day and night of burner A, so as to improve the stability of fire inspection signal, and protects
