Abstract

The utility model relates to a full water and horizontal type ambient pressure hot water boiler using gas fuel, the periphery of the entire boiler body 18 is provided with a heat-insulating layer 22, and is supported by a support frame 19 and a base 17. A burner 1 is installed in a boiler chamber 13 passing through a front lower water tank 2, the boiler chamber 13 is communicated with a lower fire pipe 20, a front smoke pipe 4, an upper fire pipe group 8, a back upper smoke chamber 9, and a smoke exhaust port 10, the front lower water tank 2 is communicated with a front upper water tank 3, a front water chamber 21, a back water tank 14, and a back water chamber 12, a water outlet 6 is communicated with the front water chamber 21, and the back water tank 14 is communicated with a water inlet 23.

Description

The complete horizontal gas normal-pressure hot-water boiler of ability of swimming

The utility model relates to the horizontal gas normal-pressure hot-water boiler of full ability of swimming technical field.

Existing gas-fired water heating boiler is provided with fire tube above only in burner hearth, there is very thick refractory material wall at smoke-box place, front and back, by the maintenance of front and rear cover plate unlatching carrying out smoke-box, thereby make whole boiler complex structure, prolonged heat time heating time, reduce heat utilization efficiency, increased energy consumption, shortened boiler service life.

The purpose of this utility model is the horizontal gas normal-pressure hot-water boiler of a kind of full ability of swimming of design, characteristics according to modern gas-fired equipment, the internal structure of redesign boiler, thereby negated that the conventional boiler internal structure is owing to the heating surface area of having used a large amount of refractory materials to cause is little, the exhaust gas temperature height, the thermal efficiency is low, fault is frequent, original shortcoming that service life is short, by transforming up hill and dale, combustion flame is caused fully in the central authorities that are heated water body, just water as optimal refractory material, be heated rapidly thereby reach, the heat utilization efficiency height, the purpose that increases the service life.

The utility model is achieved in that whole cooker furnace body 18 peripheries have heat-insulation layer 22 and supported by bracing frame 19 and base 17, combustor 1 is contained in the burner hearth 13 by preceding lower header 2, burner hearth 13 and following fire tube 20, front smoke chamber 4, go up that smoke-box 9 and exhaust opening 10 communicate on fire tube group 8, the back, preceding lower header 2 communicates with preceding upper water box 3, front water chamber 21, rear water box 14 and back hydroecium 12, delivery port 6 communicates with front water chamber 21, and rear water box 14 communicates with water inlet 23.

The utility model has the advantages that: because structurally direct as the best refractory material the water in the boiler, combustion flame is caused fully in the central authorities that are heated water body, like this, the whole steel construction of boiler is surrounded contact by water body fully, add water body good heat transfer performance and mobile naturally, make whole steel construction be heated evenly, and the steel temperature remains at below 100 degree, so stopped the fracture phenomena of the steel caustic cracking that causes because of combustion high temperature basically, overcome inevitably maintenance problem repeatedly of general boiler, found the reliable method in service life of prolonged boiler effectively, fundamentally cancelled the various refractory materials that conventional boiler must be used, combustion flame is caused fully in the central authorities that are heated water body, strengthened the water body heating surface area, shortened heat time heating time, it is the most direct that heat energy is obtained, the most effective utilization, thereby reduced energy consumption significantly, saved the energy, reduced pollution, this boiler is novel, reasonable in design, low cost of manufacture.

Below in conjunction with accompanying drawing, the utility model is described further with embodiment:

This figure is the utility model structural representation.

In the accompanying drawing: 1, combustor, 2, preceding lower header, 3, preceding upper water box, 4, front smoke chamber, 5, exhaust outlet, 6, delivery port, 7, Pressure gauge, 8, go up the fire tube group, 9, smoke-box on the back, 10, exhaust opening, 11, back smoke-box down, 12, the back hydroecium, 13, burner hearth, 14, rear water box, 15, sewage draining exit, 16, temperature controller, 17, base, 18, boiler body, 19, bracing frame, 20, fire tube down, 21, front water chamber, 22, heat-insulation layer, 23, water inlet.

Pump operation makes water enter rear water box 14 by water inlet 23, enters back hydroecium 12, preceding lower header 2, front water chamber 21 and preceding upper water box 3 then successively; The flame that is produced by combustor 1 enters burner hearth 13 and goes up smoke-box 9 by last fire tube group 8 backhauls to the back through fire tube 20 down again to front smoke chamber 4, and waste gas is discharged through flue 10, and whole heat cycles is heated the water in the said vesse and forms to circulate and is used for heating; Monitoring water body running temperature when temperature controller 16 is used for boiler operatiopn; Pressure gauge 7 is used to guarantee when unexpected superpressure appears in boiler out of service.
