Abstract
A heating boiler is composed of boiler body on the upper part of boiler body, vertical structure, insulating layer outside the boiler body, spiral sandwich layer welded by metal plates from inside to outside and with water in it, spiral flue between sandwich layer walls, and reverse flow of water and fume. The utility model discloses a helical structure against current, it is rational in infrastructure, make simply, with low costs, heat transfer efficiency is high moreover, is the ideal equipment of heating.
Description
The utility model relates to a kind of boiler, specifically a kind of heating boiler.
At present, the heating boiler major part is made up of pot body, body of heater, wherein is provided with the cavity water route that metal tube or metallic plate are welded in the pot body mostly, and their cross arrangements are in the pot body, and the pot body is positioned at upper of furnace body or outside, the external heat-insulation layer that is provided with of pot.The said apparatus heating surface inequality of being heated, the exhaust gas temperature height, heat transfer temperature difference is little, and the working medium flow process is unreasonable, and heat transfer efficiency is low.
The purpose of this utility model overcomes the deficiency of existing heating boiler exactly, provides a kind of rational in infrastructure, makes simply, and heating surface area is big, the heating boiler that heat transfer efficiency is high.
For achieving the above object, a kind of heating boiler is provided with a pot body, body of heater, heat-insulation layer, and the pot body is characterized in that in upper of furnace body pot body is processed into spiral interlayer by metallic plate from inside to outside, and the interlayer inner chamber is equipped with water, forms spiral flue between the interlayer wall.The high-temperature flue gas of burner hearth is discharged along the popular heat release of spiral flue to exhaust opening from inside to outside, recirculated water enters along the spiral interlayer from outside to inside, discharge from the central upper delivery port, form working medium whole process countercurrent heat-transfer, also be provided with the balance waste-heated water-tank at the boiler top, keep high drum water level, the balance boiler does not have pressure, but and automatic water supplement.
The utility model heating boiler has adopted the adverse current helical structure, heating surface is big, rational in infrastructure, heat transfer efficiency is high.
Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed description.
Fig. 1 is the utility model structural representation, also is the schematic diagram of embodiment.
Fig. 2 is the cut-away view of Figure 1A-A.
As shown in FIG., a kind of heating boiler, be provided with pot body 2, body of heater 7, the pot body is in upper of furnace body, and vertical structure, its pot body are to make sped structure by the general steel plate weldering, the outside is provided with heat-insulation layer 6, spiral interlayer inner chamber is equipped with water 3, and cold water is that the water inlet 16 from the outside enters, and discharges from the delivery port 1 of pot body central upper.Form spiral flue 4 between the interlayer wall, high-temperature flue gas discharges popular heat release to exhaust opening 15 by burner hearth 5 from inside to outside along the spiral flue and discharges; Cold water enters popular the heat absorption to delivery port 1 of spiral interlayer inner chamber by water inlet 16 and discharges.Thus, formed working medium whole process countercurrent heat-transfer, working medium is under the big temperature difference works, even because of the spiral plate crack again, working medium turnover flow path resistance equalization, so refrigerant flow rate is stable, heating surface is enough big in addition, the heat transfer efficiency height.Body of heater 7 is formed by general steel plate weldering system, is made up of the cinder chamber 10 of the combustion chamber 8 on top, bottom and air channel 13, fire grate 9 etc., is provided with refractory lining 14 and heat-insulation layer outside the combustion chamber.Coal-fired burning on fire grate 9, the high-temperature flue gas of generation enters the heat release of spiral flue from burner hearth 5.Remove cinder notch 11 opposites in cinder chamber and be provided with blast orifice 12, air enters through the air channel 13 by blast orifice, after cinder chamber 10 absorbs afterheat of slags, blast in the fire coal through fire grate again, combustion chamber 8 bottom periphery be provided with overfiren air port several, blast through the secondary wind of preheating from this air port and to have strengthened burning, reduced fuel consumption, improved burn-off rate.In addition, be provided with the balance waste-heated water-tank in addition, do not press, keep full water but have in the balance pot body on boiler top, and can automatic water supplement, smoke discharging residual heat can also be utilized.
This heating boiler, owing to adopted the adverse current helical structure, big heating surface, low heat transfer coefficient, low exhaust gas temperature and UTILIZATION OF VESIDUAL HEAT IN have been facilitated the high thermal energy conversion efficiency of boiler. After tested, this boiler series thermal efficiency can reach 80%-88%, improves 15-30% than the general heating boiler thermal efficiency; Rational in infrastructure because of it, to make simply, cost is lower, can obtain good energy-saving effect and economic results in society.
Claims (2)
1, a kind of heating boiler is provided with a pot body, body of heater, and the pot external body has heat-insulation layer, and the pot body is characterized in that in upper of furnace body pot body is processed into spiral interlayer by metallic plate from inside to outside, and the interlayer inner chamber is equipped with water, forms spiral flue between the interlayer wall.
2, heating boiler as claimed in claim 1 is characterized in that the water inlet of said spiral interlayer inner chamber water is located at the external side of pot, and delivery port is located at a pot body central upper.
