Abstract
The utility model provides a flame direct-heating hot water stove. The utility model has the structural proposal that the lower half part of a stove body is horizontally provided with a half open combustion chamber which forms a semicircle at the upper part, opens at the lower part, and is inserted in the water by a metal plate at both sides. The upper part of the combustion chamber is provided with water spraying row pipe with a plurality of small holes. The flame direct-heating hot water stove has the advantages of large heat exchange area, complete heat exchange, high heat efficiency, safe operation, simple structure, very convenient installation and maintenance, metal material saving, easy manufacture, and low cost, has the normal pressure in the inner part, and reduces the size and the weight. The utility model can be used for the situations of heating or other needing to supply the hot water.
Description
It is the device that fuel adds hot water with liquid or gas that the utility model relates to a kind of, especially a kind of flame direct-heating type water heater.
The most of indirect mode that adopts of present widely used water heater, the metal material consumption is big, and the life-span is short, inconvenient maintenance, the thermal efficiency can't further improve.A small amount of water heater has adopted the direct mode of heating of flame, and simple in structure, the metal material consumption is few, and volume is little, thermal efficiency height.The water heater that wherein has adopts flame directly to spray to the pond, and combustion conditions is undesirable.The employing enclosed burning chamber that also has absorbs radiant heat, and then utilizes the cold fluid and hot fluid heat exchange to absorb flue gas heat, its structure more complicated, and certain pressure is also born in the combustion chamber simultaneously.
The purpose of this utility model provides a kind of structure that adopts the semi-open-type combustion chamber, simple shape, easily manufactured, easy maintenance, whole equal flame direct-heating type water heaters of pressure-bearing not of member.
Technical solution adopted in the utility model is: the Lower Half of body of heater (2) is horizontal, and a top is set is that semi-circular, lower open, both sides metallic plate insert the semi-open-type combustion chamber (3) in the water, and the one water spray comb (4) that has a plurality of apertures is arranged at (3) top in the combustion chamber.
This water heater heat exchange area is big, and heat exchange is complete, thermal efficiency height, and inner normal pressure, safe and reliable to operation; Simple in structure, installation and maintenance are very convenient; Metal material is saved, and makes easily, and volume weight reduces greatly, and is with low cost.Can be used for heating or other occasions that needs hot water to supply, have vast market demand and good economic benefit.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is by combustor (1), body of heater (2), semi-open-type combustion chamber (3), and water pipeline (4), exhanst gas outlet (5), water inlet (6), delivery port (7), overfall (8), sewage draining exit (9) is formed.The combustor (1) that outside the left side central portion of body of heater (2) is logical, connects, the Lower Half of body of heater (2) is horizontal, and a top is installed is that semi-circular, lower open, both sides metallic plate insert the semi-open-type combustion chamber (3) in the water, body of heater (2) top left side has exhanst gas outlet (5) and right side water inlet (6), water inlet (6) connects a water spray comb (4) that has a plurality of apertures that is located at top, combustion chamber (3), body of heater (2) bottom one side has delivery port (7) and overfall (8), and sewage draining exit (9) is established in the bottom.
The combustor of above-mentioned member (1) is used for fuel (fuel oil or combustion gas) and air mixed combustion are formed flame.Semi-open-type combustion chamber (3) is used for guaranteeing combustor flame burning space and burning condition, plays the photothermal effect that partially absorbs simultaneously.Water spray comb (4) is used for and will enters the interior cold water of pipe from water inlet by the vaporific cold water of the ejection becoming of the aperture on the pipe.Overfall (8) is used for keeping the interior peak level of body of heater (2).
When this embodiment worked, fuel produced flame by combustor (1) burning and sprays to the right side from the left side level of open type combustion chamber (3).The metallic plate of heating flame chamber, flame top (3), heat is absorbed by the current in combustion chamber (3) outside, and the flame bottom is the body of heater water surface, can directly absorb most of radiant heat.The top that flue gas behind the flame combustion rises to combustion chamber (3) from the right side and the space between the body of heater (2) of combustion chamber (3), flue gas flows from right to left, with the further direct heat transfer of vaporific cold water of water spray comb (4) ejection, the exhanst gas outlet (5) by the left end top of body of heater (2) discharges out of the furnace at last.Cold water enters water spray comb (4) by water inlet (6) and is emitted into vaporific from the aperture on the pipe, the outside that is dropped to combustion chamber (3) by the gravity effect flows to body of heater (2) bottom, in this process, absorb heat and become hot water, outside delivery port (7) flows out stove, use at last for the user.
Claims (2)
1, a kind of flame direct-heating type water heater, body of heater connects combustor outward, exhanst gas outlet and water inlet are arranged at the top, delivery port is arranged at the bottom, it is characterized in that: the Lower Half of body of heater (2) is horizontal, and a top is set is that semi-circular, lower open, both sides metallic plate insert the semi-open-type combustion chamber (3) in the water.
2, water heater according to claim 1 is characterized in that: the one water spray comb (4) that has a plurality of apertures is arranged at (3) top in the combustion chamber.
