Abstract

The utility model relates to a full wet-back type vacuum hot-water boiler, belongs to the field of vacuum boilers, and is suitable for the vacuum hot-water boiler. The vacuum hot-water boiler has the technical scheme that a front water jacket communicated with a water jacket is connected on the water jacket in a boiler casing; a hole is formed on the front water jacket; and a combustor is fixed in the hole. The utility model has the beneficial effects that a front smoke chamber is changed into the water jacket and a boiler wall of a heat exchange chamber is changed to be an arc-shaped structure, so that the service life and the thermal efficiency are improved, and the maintenance cost and the running cost are reduced.

Description

Complete wet back of the body type vacuum hot water boiler
One: technical field:
The utility model belongs to the vacuum boiler field.
Two: background technology:
Traditional vacuum boiler furnace front is dried back of the body formula structure, furnace front is a front smoke chamber, dried back of the body formula structure is the heat insulation layer that is built into refractory cement in the front smoke chamber, being built into heat-insulation layer with the alumina silicate felt constitutes, the temperature height of front smoke chamber, boiler stop to start frequent, and the heat insulation layer of front smoke chamber and heat-insulation layer are worked under the temperature that often changes, ftracture easily, come off, cave in, damage, cause the accident.In addition, the temperature height of front smoke chamber, the heat dissipation capacity at front smoke chamber place is just very big, and this part heat is to waste.Besides, rectangular cell body shape is adopted in the furnace wall of heat-exchanging chamber, owing to be rectangular cell body shape, the ability of bearing pressure is just poor, destroys gas leakage at right angle turn easily, and vacuum is difficult for guaranteeing.Because there is above shortcoming in present vacuum hot water boiler, will improve these shortcomings.
Three: technology contents:
The purpose of this utility model will be invented a kind of front smoke chamber exactly and directly is made of water jacket, the furnace wall of heat-exchanging chamber and furnace shell be connected to the complete wet back of the body type vacuum hot water boiler that arc is connected.
The technical scheme that the utility model technical solution problem is adopted is: connect a preceding water jacket that communicates with water jacket on the water jacket in furnace shell, have the hole on the preceding water jacket, be fixed with burner in the hole.
The beneficial effects of the utility model are: front smoke chamber changes water jacket into, and the furnace wall of heat-exchanging chamber changes arcuate structure into, has improved the service life and the thermal efficiency, reduces maintenance cost and operating cost.
Four: description of drawings:
Fig. 1 is the cross-sectional schematic of facing of the present utility model, and Fig. 2 is the A-A sectional schematic diagram of Fig. 1.
Five: the specific embodiment:
Describe details of the present utility model and working condition in detail in conjunction with Fig. 1, Fig. 2.Vacuum hot water boiler all is by furnace shell 4 generally speaking, the water jacket 6 in the furnace shell, burner hearth 2, burner 1, smoke pipe 3, chimney 5 hot water exchangers 7, and the water inlet pipe 8 of hot water exchanger and hot-water outlet pipe's 9 compositions.The heating agent of vacuum hot water boiler is the water of 6 li of water jackets, and after the water in the water jacket was heated, by the water of the required usefulness of hot water exchanger 7 heating, the thermal efficiency of vacuum boiler was higher, so adopt more.Connect a preceding water jacket 12 that communicates with water jacket 6 on the water jacket 6 in furnace shell 4, have the hole on the preceding water jacket, be fixed with burner 1 in the hole.The inner surface of preceding water jacket 12 is directly to contact with the fire of burner hearth 2 internal combustion, the water that therefore preceding water jacket is 12 li directly is heated, originally were front smoke chamber at preceding water jacket 12 places, be that heat insulation layer and heat-insulation layer occupy, water jacket 12 before changing into now, this has just improved the thermal efficiency, also reduces the damage of heat insulation layer and heat-insulation layer simultaneously.In the hole of preceding water jacket 12, be fixed with flange 13, use screw 14 fixed combustion devices 1 on the flange.Wall 10 at the heat-exchanging chamber 15 on furnace shell 4 tops is made the garden arc, fixedlys connected with the circular arc of furnace shell 4.Because it is in the arc-shaped that the wall 10 of heat exchanger 15 is done, bearing capacity increases, and reduces the breakage of pressure, thereby has improved service life.

Claims (2)

1, a kind of complete wet back of the body type vacuum hot water boiler, it is characterized in that: the water jacket (6) in furnace shell (4) is gone up and is connected a preceding water jacket (12) that communicates with water jacket (6), has the hole on the preceding water jacket, is fixed with burner (1) in the hole.
2, a kind of complete wet back of the body type vacuum hot water boiler according to claim 1 is characterized in that: the wall (10) at the heat-exchanging chamber (15) on furnace shell (4) top is made the garden arc, fixedlys connected with the circular arc of furnace shell (4).
