Abstract
The utility model discloses an integrated front smoke chamber for a steam boiler. The integrated front smoke chamber comprises a smoke chamber body, wherein a smoke tube connecting cavity is arranged above the smoke chamber body; a combustor connecting cavity is arranged below the smoke chamber body; a combustor mounting hole is formed in the center of the combustor connecting cavity; the combustor connecting cavity is detachably connected with the smoke chamber body; a heat insulation and preservation layer is arranged on the outer circumferential surface of the combustor mounting hole, and comprises a refractory layer and a heat-preservation layer; the heat-preservation layer is close to the outer side of the smoke chamber body; a plurality of forcers are arranged in the refractory layer and the heat-preservation layer respectively; a tapered opening is formed in the side, close to a furnace body, of the combustor mounting hole. According to the integrated front smoke chamber for the steam boiler, due to the adoption of a detachable design for the combustor connecting cavity and the smoke chamber body, the combustor connecting cavity is required to be disassembled from the smoke chamber body only when a combustor is replaced, only a small part of the heat insulation and preservation layer in the combustor connecting cavity is damaged during disassembling, and damage to the whole front smoke chamber is avoided.
Description
Technical field
The utility model relates to a kind of fuel oil or gas-steam boiler, particularly relates to the integral type front smoke box that steam boiler connects burner one end.
Background technology
Fuel oil or gas-steam boiler have because of it during advantages such as energy-conservation, efficient, safe ready are widely used in daily life and produce, the high-temperature flue gas that the fuel oil of burner ejection or combustion gas generate at stove chamber inner combustion flows into by smoke box in heat exchange smoke pipe, carry out heat exchange by the cold water in outer surface and the body of heater of heat exchange smoke pipe again, cool water heating is become to steam, be finally transported to each application scenario by jet chimney.For making boiler increase heat exchanger effectiveness, smoke pipe adopts three return structures conventionally, like this, at boiler front end---this one end that is install combustion device need arrange a front smoke box.In order to make boiler outward appearance clean and tidy, be simultaneously also in order to be incubated, conventionally the installation of front smoke box and burner is made of one to formula, and thermal insulation separation thermosphere is set in front smoke box.Although adopted the integral type front smoke box of this kind of structure beautiful and clean, but in the time changing burner, whole front smoke box all need be pulled down, and can destroy the thermal insulation separation thermosphere in front smoke box in removing burner, cause the thermal insulation separation thermosphere of whole front smoke box again to make, if the different words of jet size of the burner of changing, also need to change whole front smoke box, cause great waste.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide one, and both to have had outward appearance clean and tidy, need not destroy overall steam boiler integral type front smoke box in the time changing burner simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steam boiler integral type front smoke box, comprise smoke box body, the top of described smoke box body has smoke pipe connection chamber, the below of described smoke box body is burner connection chamber, the center of described burner connection chamber has a burner installing hole, and described burner connection chamber and smoke box body are detachable, and the outer peripheral face of described burner installing hole has insulating.
Described insulating comprises flame retardant coating and heat-insulation layer, and described heat-insulation layer is near the external side of smoke box.
In described flame retardant coating and heat-insulation layer, there are respectively several bitch.
Described burner installing hole has a tapered opening near body of heater one side.
Adopt steam boiler integral type front smoke box of the present utility model, by the design for disassembly of burner connection chamber and smoke box body, in the time changing burner, only burner connection chamber need be pulled down from smoke box body, when dismounting, only destroy a small amount of insulating in burner connection chamber, and needn't destroy whole front smoke box.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-smoke box body, 2-smoke pipe connection chamber, 3-burner connection chamber, 4-burner installing hole, 5-insulating, 6-flame retardant coating, 7-heat-insulation layer, 8-bitch, 9-tapered opening, 10-flanging.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of steam boiler integral type front smoke box, comprise smoke box body 1, the top of described smoke box body 1 has smoke pipe connection chamber 2, the below of described smoke box body 1 is burner connection chamber 3, the center of described burner connection chamber 3 has a burner installing hole 4, smoke pipe connection chamber 2 is used for connecting smoke pipe, and burner installing hole 4 is used for the nozzle segment of install combustion device, conventionally also need to arrange thermal insulation layer smoke box body 1 is interior, prevent that the high temperature in boiler from conducting out, in sum, basically identical with the structure of existing steam boiler integral type front smoke box.
The innovative point of steam boiler integral type front smoke box of the present utility model is mainly that described burner connection chamber 3 and smoke box body 1 are detachable, be that described burner connection chamber 3 is an independent part of making, for preventing that the heat in boiler from conducting out by burner connection chamber 3, the outer peripheral face of described burner installing hole 4 has insulating 5.
Because the insulating that outer peripheral face has 5 of described burner installing hole 4 will bear the high temperature of the high-temperature flue gas in burner hearth towards a side of boiler internal, therefore the insulating 5 of steam boiler integral type front smoke box of the present utility model comprises flame retardant coating 6 and heat-insulation layer 7, described heat-insulation layer 7 is near smoke box body 1 outside.Like this, flame retardant coating 6 is used for bearing the high temperature of the high-temperature flue gas in burner hearth, and heat-insulation layer 7 a small amount of heat that guarantee is leaked from flame retardant coating 6 is transmitted to boiler outer surface.Described flame retardant coating 6 adopts high temperature resistant brick to add concrete conventionally, and heat-insulation layer 7 adopts the materials such as asbestos to make conventionally.
In order to ensure the flame-proof thermal insulation material and the adhesive force of burner connection chamber 3 in flame retardant coating 6 and heat-insulation layer 7, described flame retardant coating 6 and heat-insulation layer 7 be interior has respectively several bitch 8.Described bitch 8 can be fixed on the wall of burner connection chamber 3 by modes such as welding, common described bitch 8 is perpendicular with the axis of burner installing hole 4, in the time making flame retardant coating 6 with heat-insulation layer 7, bitch 8 is nuzzled in flame-proof thermal insulation material, in order to improve the adhesive force of bitch 8, also can a flanging 10 be set at the head of bitch 8.
In order to make the spout of burner more firm with being connected of burner connection chamber 3, described burner installing hole 4 has a tapered opening 9 near body of heater one side.By burner nozzle end larger diameter is placed in tapered opening 9, burner can not come off from burner installing hole 4, meanwhile, tapered opening 9 also has the effect of the high-temperature fuel gas diffusion of burner nozzle ejection, and high-temperature fuel gas is evenly flowed in burner hearth.
