Description

The combustion and steam stove

The utility model belongs to the improvement of steam boiler, particularly the combustion and steam stove.

The combustion system of existing fire tube steam oven is that fire burns in lower combustion chamber, the radiating tube heat radiation, and the flue gas of generation is drained from the chimney on top, its weak point is to have quite a few heat energy directly to drain from chimney, the area of dissipation of combustion tube in stove is little, and the quantity of steam of generation is little, and the thermal efficiency is low.

The purpose of this utility model is to provide a kind of combustion and steam stove, changes traditional burning and fume exhausting type, enlarges area of dissipation, improves the thermal efficiency, improves the output of steam.

The utility model is achieved in that a kind of combustion and steam stove, comprise body of heater, burner, heat pipe and flue, the capping of vertical type cylinder shape body of heater is provided with steam (vapor) outlet and safety valve, the collecting and distributing pipe both sides that are positioned at body of heater internal upper part central authorities are being communicated with downward-sloping uniform heat pipe, outside at heat pipe is evenly equipped with heat sink, the lower end of heat pipe is positioned at outside the body of heater, on the combustion chamber of the end of heat pipe connection, natural gas line is installed respectively, electronic striking system and steam air mixing tube, collecting and distributing pipe is the breeches pipe of head and the tail sealing, the uniform spirality smoke pipe that is being communicated with on the herringbone breeches pipe of collecting and distributing pipe bottom, the lower end of smoke pipe is communicated with the flue of body of heater bottom, on the feed pipe of the bottom of body of heater setting Pressure gauge has been installed.

During the utility model work, elder generation is by feed pipe transporting water in body of heater of bottom of furnace body, neat gas burner is lighted by the electronic striking system, simultaneously, the mixed gas that passes to an amount of air and steam is participated in burning, the pyrotechnics of burning enters collecting and distributing pipe along the heat pipe that is tilted to, heated heat pipe is by tube wall and heat sink heating, water in the vaporization body of heater, pyrotechnics in the collecting and distributing pipe continues to move downwards along the spiral smoke pipe, the water of the heat heating furnace body bottom that uniform spiral smoke pipe distributes, enlarge area of dissipation, improved the thermal efficiency, thereby also improved the output of steam.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the schematic perspective view of analysing and observe of heat pipe.Below in conjunction with accompanying drawing the utility model further is described, a kind of combustion and steam stove, comprise body of heater, burner, heat pipe and flue, the capping of vertical type cylinder shape body of heater (3) is provided with steam (vapor) outlet (2) and safety valve (1), collecting and distributing pipe (4) both sides that are positioned at body of heater (3) internal upper part central authorities are being communicated with downward-sloping uniform heat pipe (5), the gradient of heat pipe (5) is that pipe shaft becomes 40 °～50 ° with horizontal angle, the cross section of heat pipe (5) is leg-of-mutton metal tube, on the bottom surface of triangle tube inwall and two side, heat conduction reinforcement (15) is being set respectively, heat conduction reinforcement (15) not only can strengthen the rigidity of heat pipe (5), face and can absorb the heat in the heat pipe and pass to tube wall, heat pipe (5) outside is evenly equipped with heat sink (6) and has increased area of dissipation, can fully distribute the heat of heat pipe (5), improve heat exchange efficiency, the lower end of heat pipe (5) is positioned at outside the body of heater (3), on the combustion chamber (7) of the end of heat pipe (5) connection, natural gas line (10) is installed respectively, electronic striking system (18) and steam air mixing tube (9), main fuel is based on natural gas, mixing air, steam mixes by a certain percentage, make the flame temperature reach higher temperature, collecting and distributing pipe (4) is the breeches pipe of head and the tail sealing, the uniform spirality smoke pipe (11) that is being communicated with on the herringbone breeches pipe of collecting and distributing pipe (4) bottom that looses, the lower end of smoke pipe (11) is communicated with the flue (14) of body of heater (3) bottom, on the feed pipe (13) of the bottom of body of heater (3) setting, Pressure gauge (12) is installed, spirality smoke pipe (11) has increased heat exchange area, augmentation of heat transfer has improved the thermal efficiency.
