Abstract
A novel boiler gasket for a cast iron condensing boiler comprises a sealing groove 1, a hearth 2, a heat collection cone heated surface 3, a smoke chamber 4, an upper connector 5, a lower connector 6 and an anticorrosion layer 7 which are cast into a whole by a casting process. Mutually communicated cavities are formed inside the sealing groove 1, the heat collection cone heated surface 3, the upper connector 5 and the lower connector 6, and the anticorrosion layer 7 is formed on the surfaces of the heat collection cone heated surface 3 and the smoke chamber 4 by a surface treatment process. Corrosion of the cast iron boiler gasket caused by acidic condensed water can be effectively prevented by the aid of the anticorrosion layer 7 formed on the surfaces of the heat collection cone heated surface 3 and the smoke chamber 4. As cast iron replaces stainless steel and cast aluminum, material cost can be reduced by more than 50% under the condition of the same power, and the novel boiler gasket for the cast iron condensing boiler is manufactured by a novel process, novel technology and novel materials and provided for the field of condensing boiler manufacture.
Description
technical field:
The present invention relates to HVAC and field of air conditioning, exactly belong to Industrial Boiler and manufacture field.
background technology:
Condensing boiler is by the water vapor condensation Cheng Shuihou in flue gas, reclaims its latent heat of vaporization again for boiler, and the thermal efficiency can meet or exceed the boiler (calculating according to Lower heat value) of 100%.At present, existing condensing boiler mainly contains two safety issues: one is the etching problem of condensing boiler, and another is steam condensation problem in flue and chimney.Condensing boiler outstanding feature utilizes condensing heat exchanger to reduce flue-gas temperature, utilize the latent heat of steam in flue gas, the sensible heat of also recovered flue gas cooling simultaneously, all that the temperature of boiler smoke is dropped to less than 100 DEG C, steam in flue gas will be condensed into weakly acidic condensed water (pH value is about 4.5), corrosion can be formed to smoke-box and caudal components thereof, in order to reach good anti-corrosion function, condensing boiler boiler sheet generally all adopts cast aluminium boiler sheet and stainless steel boiler sheet, these two kinds of materials have good antiseptic effect, but cast aluminium and stainless steel boiler sheet cost higher, simultaneously, the condensing boiler capacity made with cast aluminium is also subject to larger restriction.
summary of the invention:
The object of the invention is just to provide a kind of low cost, Novel condensation cast-iron boiler boiler sheet that corrosion resistance is strong.
The present invention is made up of seal groove, burner hearth, thermal-arrest cone heating surface, smoke-box, upper connector, lower connector, anticorrosive coat, seal groove, burner hearth, thermal-arrest cone heating surface, smoke-box, upper connector, lower connector are by casting technique cast solid, and the inside of seal groove, thermal-arrest cone heating surface, upper connector, lower connector is all the cavity body interconnected, burner hearth, thermal-arrest cone heating surface, smoke-box three part are arranged in upper, middle and lower on boiler sheet, form one deck anticorrosive coat on thermal-arrest cone heating surface surface and smoke-box surface by process of surface treatment.Wherein, anticorrosive coat can be made by coating one deck carborundum, also can form one deck anticorrosive coat by nitridation process, anticorrosive coat can cover the thermal-arrest cone whole outer surface of heating surface and smoke-box on the surface, also can to cover in the middle part of thermal-arrest cone heating surface with outer lower face surface and smoke-box on the surface.
The present invention, by the anticorrosive coat on thermal-arrest cone heating surface surface and the formation of smoke-box surface, effectively can prevent acid condensate water to the corrosion of cast iron boiler-chip, have stronger antiseptic effect, prolonged boiler sheet service life; Simultaneously, with the condensing boiler that the present invention manufactures, owing to adopting cast iron quality to replace stainless steel and cast aluminium material, condensing boiler manufacturing cost can be significantly reduced, under Same Efficieney condition, to compare with stainless steel condensing boiler with existing cast aluminium and can reduce material cost more than 50%.The present invention provides a kind of cast iron condensing boiler boiler sheet using new technology, new technology, new material to produce system for condensing boiler manufactures field.
accompanying drawing illustrates:description of the present invention comprises 1 width accompanying drawing, and the drawing of accompanying drawing is described as follows:
Fig. 1 is front elevational schematic of the present invention
Fig. 2 is side elevational cross-section schematic diagram of the present invention

In figure: 1 is seal groove, 2 is burner hearth, and 3 is thermal-arrest cone heating surface, and 4 is smoke-box, and 5 is upper connector, and 6 is lower connector, and 7 is anticorrosive coat.
detailed description of the invention:
Illustrate below in conjunction with accompanying drawing, the present invention be described in detail:
The present invention is by seal groove 1, burner hearth 2, thermal-arrest cone heating surface 3, smoke-box 4, upper connector 5, lower connector 6, anticorrosive coat 7 forms, seal groove 1, burner hearth 2, thermal-arrest cone heating surface 3, smoke-box 4, upper connector 5, lower connector 6 is by casting technique cast solid, and seal groove 1, thermal-arrest cone heating surface 2, upper connector 5, lower connector 6 inside is all the cavity body interconnected, burner hearth 2, thermal-arrest cone heating surface 3, smoke-box 4 is presented, in, lower layout, form one deck anticorrosive coat 7(on thermal-arrest cone heating surface 3 surface and smoke-box 4 surface by process of surface treatment and see Fig. 1 and Fig. 2).Wherein, anticorrosive coat 7 is made by coating one deck carborundum; Also one deck anticorrosive coat 7 can be formed by nitridation process.Anticorrosive coat 7 can cover thermal-arrest cone heating surface 3, and all outer surface and smoke-box 4 on the surface, also can to cover in the middle part of thermal-arrest cone heating surface 3 with outer lower face surface and smoke-box 4 on the surface.
