The clean energy fuel of type, can efficiently solve the contradiction between boiler fired coal and environmental pollution.National energy-saving environmental protection in recent years
Emission reduction policy is put into effect in succession, but also oil-burning gas-fired boiler has obtained unprecedented development.For oil-burning gas-fired boiler, combustion
Burner is the core equipment of boiler, is rationally to mix fuel with air, makes the equipment of fuel stabilization kindling and completely burned.Combustion
How high-temperature region of the burner head as burning, be effectively protected and seem without burning out it and be even more important.
Combustion port device in the prior art, the mode for being largely all made of refractory material are arranged, on the one hand
It is higher close to the inside temperature of burner head, and the inside temperature far from burner head is lower, and entire refractory concrete has temperature
It is poor to spend, and adds refractory material hot soak condition, be easy to cause cracking and fails, on the other hand, refractory material is to combustion
Burner head cannot play cooling, and burner head is chronically at the radiation of high-temperature flue gas, the cycle of operation grown certainly will will lead to it is disconnected
It splits, influences the normal combustion and economical running of boiler.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of coiled water cooled burner interface
Device installs water cooling coil additional at burner hearth import front panel, and the part heat of burner hearth entrance is absorbed by external recirculated water
Amount, to play the role of water cooling protection to the head of burner, also makes entire refractory material bulk temperature and internal temperature
Difference reduces, and extends the service life of burner and insulating, also saves on the operating cost of user's boiler.
According to technical solution provided by the utility model: coil pipe Water-cooling type burner interface arrangement, including interface shells, institute
State interface shells connection burner hearth, be provided with burner head in the interface shells, the interface shells and the burner head it
Between be provided with fire proofing material, the interface shells end face is provided with combustion port panel, the combustion port panel connection
First water pipe and the second water pipe, first water pipe are located at the top of second water pipe, first water pipe and described second
Water pipe is connected in the round coil between the interface shells and the burner head.
The fire proofing material includes refractory concrete and alumina silicate fibre, institute as a further improvement of the utility model,
State the right side that refractory concrete is located at the alumina silicate fibre.
The round coil position as a further improvement of the utility model,
Between the burner head and the fire proofing material.
The round coil part is located among the fire proofing material as a further improvement of the utility model,.
The round coil is helically cylindric as a further improvement of the utility model,.
The round coil and the burner head are located at same axis as a further improvement of the utility model,.
The utility model compared with prior art, has the advantages that
1, the utility model structure is simple, compact, connection and reasonable arrangement, and manufacturing cost is lower；Effectively reduce burning
The loss of heat.
2, the utility model all plays the role of water cooling protection to the head of burner and insulating, extends combustion
The service life of burner also saves on the operating cost of user's boiler.
