Description

Horizontal mini boiler

The utility model relates to field of boilers.More particularly it is to be used for heating area at 2000m ²Places such as following office, shop, hotel, restaurant, school, hospital, family, open-air unit, frontier sentry, haulage vehicle integrate heating, have a bath, produce the horizontal miniature boiler of function such as warm water.

Miniature boiler up to now, its boiler body mostly are vertical greatly.This boiler structure is simple, but its heat exchange process is short, and heat-transfer effect is poor; Highly big, fixing comparatively complicated during installation; Rated power and heating area are less.The utility model patent of No. 92219476.9 " the multifunction micro boiler " by name of being authorized by Patent Office of the People's Republic of China comes to this.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and a kind of thermal efficiency height, energy savings are provided, and rated power and heating area are bigger, and be easy for installation, rational in infrastructure, integrates heating, has a bath, produces the horizontal miniature boiler of functions such as warm water.

In order to achieve the above object, the horizontal miniature boiler of the utility model by base, be installed in boiler body on the base, be installed in flue on the boiler body, be installed in burner on the port of boiler body, be installed on the port of boiler body can through port in the combustion chamber, spray fuel oil oil pump, be installed on the port of boiler body blower fan that can air blast in the combustion chamber and be installed in computer and the control circuit thereof on the base boiler controlled automatically and constitute.Boiler body is by having water inlet, the water tank type body of heater of delivery port and sewage draining exit, be welded on front, water tank type body of heater bottom have port then right side of face have the combustion chamber of semicircle shape flue, be welded on water tank type body of heater back communicate with the semicircle shape flue lining with refractory masses and in having every back smoke box, be welded on water tank type body of heater front upper and lining front smoke box with refractory masses, the one group of smoke pipe that is welded on water tank type body of heater inner right side and links to each other on their right side with back smoke box and front smoke box, be welded on water tank type body of heater inside left and link to each other in their left side with front smoke box and back smoke box another organize smoke pipe and form.Flue is welded on back smoke box left upper portion and communicates with it.Said structure is a horizontal type structure, and is easy for installation, rational in infrastructure, and rated power and heating area are all bigger.

The fuel of this horizontal miniature boiler adopts kerosene or diesel oil.After fuel oil pumped into burner by oil pump, through the burner atomizing, the air of sending here with air blast was mixed into gas mixture gas, burns in the combustion chamber.The high-temperature flue gas radiation of burning heats up the medium-water in the outer water tank formula body of heater of combustion chamber on the combustion chamber.Subsequently, flue gas go out the combustion chamber successively through after another group smoke pipe, the smoke box left side, back in left side in the one group of smoke pipe, front smoke box, water tank type body of heater on right side in the smoke box right side, water tank type body of heater, after flue discharge in the outside atmosphere.In this flow process of high-temperature flue gas, water is just heated, and enters heating system by delivery port again.Backwater then enters the water tank type body of heater by water inlet.Sewage draining exit then is used for effluent sewerage and incrustation scale.The operation of horizontal miniature boiler is all controlled automatically by computer and control circuit thereof.

The periphery of water tank type body of heater is also being welded another interlayer water tank that has water inlet pipe and outlet pipe.The interlayer water tank is an independently water system.It is that cold water heat exchange that the heat exchanger by the outer sandwich-type of water tank type body of heater makes this system enter interlayer becomes the warm water about 40～50 ℃, specializes in the usefulness of having a bath.Thereby further improved the thermal efficiency, saved the energy, integrated heating simultaneously, have a bath, produce multiple functions such as warm water.

The task of the horizontal miniature boiler of the utility model comes to this and finishes.

A kind of thermal efficiency height, energy-conservation, rated power are provided the utility model and heating area is bigger, easy for installation, rational in infrastructure, long service life, exhaust gas temperature are low, pollute light multi-functional horizontal miniature boiler.Compare with the past like product, the thermal efficiency of the present utility model has improved 3～9%, saves steel 20～30%, and exhaust gas temperature has reduced by 90～140 ℃.The utility model can be widely used in heating area 2000m ²The heating in places such as following shop, hotel, school, hospital, family, restaurant, vehicle, frontier sentry, have a bath, during warm water provides.

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

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

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

Fig. 3 is the A-A cutaway view of Fig. 2.

As seen from Figure 1, the utility model embodiment is by base 1, boiler body 2, and flue 3 is installed in oil pump 4, blower fan 5 and burner 6 on the port 12, and computer and control circuit 7 thereof constitute.The utility model uses kerosene or diesel oil to do fuel oil, pumps into the combustion chamber by oil pump 4 by port 12.Blower fan 5 air blast are combustion-supporting.Whole combustion process is controlled automatically by computer and control circuit 7 thereof.After present embodiment and heating system (comprising fin, pipeline etc.) thereof are filled with water, open the utility model, computer and control circuit thereof just borrow electronic ignition that fuel oil is lighted.After this high-temperature flue gas radiation makes the water in the outer water tank formula body of heater of combustion chamber be heated intensification on the combustion chamber.High-temperature flue gas again from the combustion chamber successively through after smoke box, one group of smoke pipe, front smoke box, another group smoke pipe, back smoke box, flue drain into outside atmosphere.In this course, the water in the water tank type body of heater constantly is heated, and enters the heating system heating.

Fig. 2 and shown in Figure 3, the boiler body 2 of present embodiment have port 12 by the water tank type body of heater 11, the front that have water inlet 8, delivery port 9 and sewage draining exit 10 and then wear by the combustion chamber 14 of semicircle shape flue 13, lining and form with the front smoke box 18 of refractory masses 15, one group of smoke pipe 19 and another group smoke pipe 20 every 16 back smoke box 17, lining with refractory masses 15 and in having.The periphery of water tank type body of heater 11 is also being welded another interlayer water tank 23 that has water inlet pipe 21 and outlet pipe 22, to produce warm water or water for bathing is provided.The periphery of water tank type body of heater 11 also can not have interlayer water tank 23 and only use for heating.

Present embodiment is horizontal, and rated power and heating area can improve 2～3 times more in the past, saves steel 30%, and exhaust gas temperature has only 160 ℃, and the thermal efficiency is up to 90%.It can be widely used in heating area 700m ²Supply heating in following various dwelling houses, the house, have a bath, produce warm water usefulness.
