Abstract
The utility model discloses a non pressure hot water gas furnace, comprising a round or square furnace casing, which is characterized in that a plurality of closing plates are fixed on the both ends of the furnace casing; a plurality of pipes are penetrated between the closing plates and hermetically fixed, an inlet pipe is fixed on the underside of the furnace shell, and at least three outlet pipes are penetrated between the clearance of upper closing plate and pipes; the outlet pipe is connected and fixed with a secondary heating chamber, the secondary heating chamber is a cavity hood type structure, and the outlet pipe is fixed on the place above furnace shell; the lower bottom surface of the secondary heating chamber is convex-concave plate structure and an outlet pipe is arranged on the upper plate of the secondary heating chamber. The utility model has the advantages of simple structure, convenience for manufacture, low costs and high working efficiency, and is therefore applicable to heating water in families and units; meanwhile, the secondary heating chamber can improve the heating efficiency of the hot water gas furnace by 30 to 40 percent.
Description
Relate to field the utility model and relate to the hot-water heating system technical field, particularly a kind of non-pressure hot water gas furnace.
Background technology is present, and the domestic hot water stove all is to adopt coal-fired directly burning, and this heating means thermal efficiency is very low, also makes the coal-fired black smoke that produces, and has polluted environment, and directly coal combustion adds the method for hot water, progressively is eliminated.In order to reduce environmental pollution, people are adopting the method for combustion gas to add hot water, eliminated of the pollution of the black smoke of coal-fired generation like this to air, the device of this burning all is to adopt the shell and tube heating furnace, its structure is to be made of circle or rectangle furnace shell, the two ends of furnace shell are fixed with shrouding, are installed with tubulation between two shroudings, and tubulation is fixed on the shrouding; The downside of furnace shell has water inlet pipe, is connected with outlet pipe between the tubulation gap of upper sealing plate.The water heater thermal efficiency height of this structure, non-environmental-pollution is the water heater of a kind of energy combustion of liquid combustion gas, is subjected to very much people's welcome.When but the hot waste gas that this fire grate is put can reach 300-500 ℃, directly drain, caused the waste of the energy.
The summary of the invention the purpose of this utility model provides a kind of non-pressure hot water gas furnace, is that the waste gas outlet side at the shell and tube water heater is equipped with second heating chamber, and the thermal efficiency of shell and tube hot water gas furnace is greatly enhanced.
The non-pressure hot water gas furnace, be that furnace shell by circle or rectangle constitutes, the two ends of furnace shell are fixed with upper and lower shrouding, be installed with tubulation and sealing and fixing between the upper and lower shrouding, the downside of furnace shell is fixed with water inlet pipe, be installed with at least three outlet pipes between the tubulation gap of upper sealing plate, outlet pipe and second heating chamber are connected and fixed, it is characterized in that: described second heating chamber is the cavity hood configuration, be fixed on the furnace shell top by outlet pipe, the bottom surface of second heating chamber is the convex-concave plate structure, at the top plate of second heating chamber outlet pipe is housed.
The utility model has the advantages that: this hot water gas furnace is simple in structure, is easy to make, and cost is low, and high efficiency is applicable to that family and collective add hot water and use.Secondary combustion chamber has improved the efficiency of heating surface 30%-40% of hot water gas furnace.Shortened heat time heating time, the convex-concave plate has strengthened endotherm area 30%.Hot water gas furnace energy savings is more than 40%.
