Description

The swirl flow combustion heater
Technical field
The utility model relates to a kind of swirl flow combustion heater, belongs to the fried food field of mechanical technique.
Background technology
Burner commonly used in the industry has partially premixed burner and complete pre-mixing type burner, but no matter is partly-premixed or all there is the possibility of tempering in the complete pre-mixing type burner.
Some at present common combustion gas frying apparatus start needs actuator, has improved the manufacturing cost of product virtually.
Summary of the invention
The utility model technical issues that need to address provide a kind of swirl flow combustion heater, and air is burnt on steady fire tube inner edge mixing limit fully with combustion gas, do not have the possibility of tempering, and burner need not actuator when starting, and can realize smooth starting at full capacity.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The swirl flow combustion heater, comprise in its structure, heating tube, the flange of heating tube end connects turbulent burner, the structure of described turbulent burner comprises, cylindrical air compartment, the air compartment rear end is sealed by end plate, connect little fiery ignitron on the end plate, the air compartment side connects combustion-aid air pipe, and the air compartment front end is connected and fixed flange, connect steady fire burns tube on the mounting flange upper wall surface, be connected with front end-plate in the steady fire burns tube, hoop is arranged the air intake hole on the front end-plate wall, and hoop is arranged the air circulator all around, the end plate centre connects gas inlet pipe, combustion gas enters the circular ring type gas nozzle of front end-plate center by gas inlet pipe, and hoop is arranged the combustion gas dispensing orifice around the gas nozzle, is connected with igniting pin and flame detection pin by end plate and front end-plate.
The further improvement of the utility model concrete structure is:
The structure of heating tube comprises, main, and the flange of main front end connects the mounting flange of turbulent burner, and the main tail end is provided with gas distributor, and gas distributor is communicated with arm.
Arm is designed to 2,3,4 or 5.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model is connected on the equipment by flange, and burning is finished in the heating tube main, so whole burner outer wall is in the normal temperature state, need not air-cooled or the use exotic material, and is simple in structure; In addition, because burner is in room temperature state fully, burner does not almost have thermal loss, the heat insulating coefficient height, and the heat exchange efficiency height, and do not have potential safety hazard.
The utility model with do, the manifold configuration heating tube is used in combination, and can make flue gas have close heat convection effect in heating tube, good effect of heat exchange, the flow resistance of flue gas is little, and is not only energy-conservation but also can reduce the power consumption of equipment.
Burner need not actuator when starting, and can realize smooth starting at full capacity, and startability is reliable, and is simple in structure, and the metal consumptive material is few.
This burner can be realized rotation to wind, thereby makes combustion air produce tangential and axial velocity, mix fully with the combustion gas of radially ejection, and sufficient combustion, the high-temperature flue gas rotation after the burning is advanced, thereby makes the heat exchange better effects if of rear portion heating tube.
