CN201177369Y - Tube-type fuel (gas) boiler - Google Patents

Abstract

The utility model discloses a tube type oil (gas)-fired boiler, which is of a horizontal cylinder shape. Water pipes are arranged in the boiler, a support plate is arranged on front of the boiler and is used to fix the water pipes, a combustor interface is arranged on front of a combustion chamber, a manhole is arranged on the back of the combustion chamber, the water pipes are connected through elbows, the burning flame burns toward the inside of an internal furnace, enters a second return passage through the diversion of fin plates, and then enters a third return passage through the diversion of the fin plates, the thermal intensity of the flame is transferred to water flowing through the water pipes through the water pipes in the boiler furnace and heated surfaces of the fin plates to finish the energy transformation process during the combustion, and then the water is discharged out of the boiler through an exhaust port of the boiler. Because the water pipes and the fin plates are taken as the entire heated surfaces, the oil (gas)-fired boiler has the advantages of large heated surface, small water capacity, less steel consumption, small volume, immediate use by immediate combustion, energy conservation, environmental protection and so on.

Description

Tubular type fuel oil (gas) boiler

Technical field

The utility model belongs to fuel oil, gas-fired water heating boiler technical field.

Background technology

Known to the applicant: present gas fuel boiler on the market, general boiler structure adopts tubular or shell chamber combustion type, tubular is a kind of burning structure that heats by the downward metabolic water heating surface of tubes of top combustion burner, but burner must be to adopt the special burner in top, the equipment cost that has increased; And the shell chamber combustion type is a kind of burning structure by simple heating horizontal water tube and flue heating surface, and the boiler water capacity is big, and energy consumption is big, and the thermal efficiency of boiler is low, and the boiler preheating uniform temperature could be used, and the capacity of furnace causes waste, the use cost height.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and provide a kind of i.e. horizontal three backhaul tubular type fuel oil (gas) boilers of usefulness that promptly burn, it can adopt ordinary burner, can guarantee result of use again, promptly burn promptly with not wasting energy, energy-conserving and environment-protective, also reduced simultaneously boiler with material amount and water capacity, dwindled the volume of boiler integral body.

The technical solution of the utility model is design like this: a kind of tubular type fuel oil (gas) boiler, comprise body of heater, burner and controller, be characterized in: it is horizontal combustion cylinder structure, the front middle part of boiler is provided with the burner interface, be provided with the flue heating surface that three layers many U type snakelike conduits are formed in the stove, every layer outward all hoop fin keel arranged, be communicated with by the elbow welding between water pipe and the water pipe, the external water inlet of an anterior outer water pipe of boiler, rear portion internal layer one water pipe of boiler picks out the mouth of a river, and the upper back of boiler is provided with exhaust opening.Combustion flame is in the flue internal combustion, by two journeys and three journey burning galleries through the exhaust opening combustion gas.

Because the utility model is the whole heating surfaces of body of heater by water pipe and fin keel, so reached that heating surface area is big, water capacity is little, steel consume less, volume is little, promptly burning is promptly with advantages such as energy-conserving and environment-protective.

Description of drawings

Fig. 1 is the utility model cut-away view.

Fig. 2 is the A-A cut-away view of Fig. 1.

Among the figure 1, deflection plate 2, insulation material 3, lagging casing 4, support plate 5, elbow 6, cover plate 7, burner interface 8, burner 9, water inlet 10, support 11, delivery port 12, fire clay 13, manhole 14, water pipe 15, fin keel 16, exhaust opening

The specific embodiment

From Fig. 1 as seen, it is horizontal cylindric that the utility model is, in the stove is water pipe 14, the stokehold is provided with fixedly water pipe of support plate 4, it before the combustion chamber burner interface 7, it behind the combustion chamber manhole 13, connect by elbow 5 between the water pipe, burned flame is to the flue internal combustion, water conservancy diversion through fin keel enters the two return passage, and the water conservancy diversion through fin keel enters three backhaul passages again, and the flame calorific intensity reaches the water that flows through in the water pipe through flue inner conduit and fin keel heating surface, conversion process of energy when finishing burning is after fire grate mouth 16 discharges out of the furnace.

Claims (2)

1, a kind of tubular type fuel oil (gas) boiler, comprise body of heater, burner and controller, it is characterized in that: it is horizontal combustion cylinder structure, the front middle part of boiler is provided with the burner interface, is provided with the flue heating surface that three layers many U type snakelike conduits are formed in the stove, every layer outward all hoop fin keel is arranged, be communicated with by the elbow welding between water pipe and the water pipe, the external water inlet of an anterior outer water pipe of boiler, rear portion internal layer one water pipe of boiler picks out the mouth of a river, and the upper back of boiler is provided with exhaust opening.
