Description

Fuel-burning boiler

The utility model relates to field of boilers.More particularly it is to be used for heating area 300-25000M ²Place such as office, shop, hotel, restaurant, school, hospital, family, savings bank, open-air unit, frontier sentry, vehicle, have heating, have a bath, produce the fuel-burning boiler of functions such as warm water.

Present fuel-burning boiler, its combustion chamber mostly is through type cylindraceous greatly, in perhaps having every cylindric about straight-through strile-back type, the end steel plate of combustion chamber i.e. the boxboard of back smoke box.The combustion chamber of this cylinder-like structure, the big inadequately coefficient of heat transfer of its area of dissipation is big inadequately, the insufficient strength height.In addition, because the combustion chamber end region temperature is high, the temperature of back smoke box is very high, and often Yin Gaowen causes back smoke box steel plate deformed, has both reduced service life, has reduced the thermal efficiency again.Except, the front smoke box in past directly is welded on the boiler body, inconvenient demolition and maintenance.

The purpose of this utility model, be to overcome above-mentioned shortcoming and defect, thereby provide a kind of combustion chamber to have big area of dissipation to improve the coefficient of heat transfer, and high mechanical strength arranged, thereby back smoke box can not improve service life because of high temperature deformation, thereby front smoke box is easy to safeguard dismounting for opening installing type, and can have have a bath, the fuel-burning boiler of multiple function such as heating.

In order to achieve the above object, the utility model by base, be installed in the boiler body on the base, be installed in flue on the boiler body, be installed in burner and blower fan and injection pump on the port of boiler body, be installed in the controller of on the base boiler being controlled and constitute.Boiler body by the water tank type body of heater that has water inlet, delivery port and temperature, manometer interface, be welded on the combustion chamber that is positioned at the front, bottom in the water tank type body of heater and has port, be welded on back smoke box that water tank type body of heater back communicates with flue, be installed in water tank type body of heater front and lining with the front smoke box of refractory masses, to be welded on the middle part that the water tank type body of heater is positioned at around the combustion chamber and one group of threaded flue communicating with front smoke box and back smoke box is formed the combustion chamber be wave structure.During work, fuel oil sprays into combustion chambers burn by burner, and the high-temperature flue gas of burning sprays into the end, combustion chamber by port, strile-backs to front smoke box along sidewall of combustion chamber again, and smoke box is discharged by flue after one group of smoke pipe around the combustion chamber enters.In this strile-backd process, heat was fully absorbed by the water in the water tank type body of heater, and the coefficient of heat transfer improves greatly, and heat exchange area increases greatly.The wave structure of middle part diameter has also changed the boundary layer of high-temperature flue gas air-flow, thereby has improved the coefficient of heat transfer except that having increased heat exchange area in the combustion chamber.Simultaneously, the flexible expansion when this structure helps combustion chamber heat expansion shrinkage has improved the mechanical strength of combustion chamber greatly.

Welding between combustion chamber right-hand member and the back smoke box sidewall and supporting, support is arranged in the water tank type body of heater.This structure makes between end, combustion chamber and the back smoke box sidewall isolates with water, thereby greatly reduces the temperature of back smoke box steel plate, has reduced distortion, has prolonged service life.Back smoke box becomes low-temperature space by the high-temperature region, has improved the thermal efficiency simultaneously.

Top in the water tank type body of heater can also be welded with the U-shaped water pipe of one group of difference opening in and arranged on left and right sides.Its left and right two opening parts are welding left and right two little water tanks respectively.One in left and right two little water tanks is being welded water inlet, and another is welding and the outlet pipe of having a bath and joining with shower nozzle.Running water, is sprayed from shower nozzle successively through a little water tank, U type water pipe, another little water tank, outlet pipe by water inlet, by the heating of the hot water in the water tank type body of heater, can be used for having a bath in the U-shaped water pipe.

Can link with securing member between front smoke box and the boiler body, seal with the asbestos packing liner.This structure both can make front smoke box be easy to demolition and maintenance, can guarantee the sealing of boiler body again, the anti-leakage heat leak gas of having gone up.

Task of the present utility model comes to this and finishes.

The utility model provides a kind of heating that both can be used for, and also can be used for having a bath, perhaps the fuel-burning boiler of the two dual-purpose.Its front smoke box is easy to demolition and maintenance, coefficient of heat transfer height, and area of dissipation is big, and the combustion chamber is strile-back type, high strength.Compare with the fuel-burning boiler in past, improved 15-40% its service life.Its exhaust gas temperature has only 140-160 ℃.Can be widely used in the occasions such as office, shop, hotel, restaurant, school, hospital, family, frontier sentry, open-air unit, motor vehicles, boats and ships.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further to describe.

Fig. 1 is the structural representation of the utility model embodiment 1.

Fig. 2 is the structural representation of the boiler body of embodiment 1.

Fig. 3 removes left view behind the front smoke box for Fig. 2.

Illustrated in figures 1 and 2, embodiment 1 is made of base 1, boiler body 2, flue 3, burner and blower fan thereof and injection pump 4, controller 5.Boiler body 2 is by having water inlet 6, and the middle part 15 that the water tank type body of heater 9 of delivery port 7 and instrumentation tap 8, the combustion chamber 11 that has port 10, back smoke box 12, front smoke box 13, threaded flue 14 are formed combustion chamber 11 is wave structure.Heat exchange area increases greatly.The coefficient of heat transfer improves.Welding between the right-hand member of combustion chamber 11 and back smoke box 12 sidewalls 16 and supporting 17, be arranged in water tank type body of heater 9.Link with securing member 18 between front smoke box 13 and the boiler body 2, seal with asbestos packing 19 liners.
