Description

High efficiency burnt gas direct-combustion boiler
Technical field
A kind of mechanical field is the utility model is related to, specifically a kind of high efficiency burnt gas direct-combustion boiler.
Background technology
Currently used boiler divides from fuel source, and some is using raw coal, moulded coal as fuel, and some is using biomass as combustion Material, but these boilers are mostly seriously polluted.Also there are some gas fired-boilers, pollution is small, and heat utilization efficiency is high, but mostly complicated, High processing costs.
The content of the invention
In order to overcome the shortcomings of that existing gas fired-boiler is complicated, high processing costs, the utility model provides a kind of high Gas Direct-fired boiler is imitated, the high efficiency burnt gas direct-combustion boiler is simple in construction, and processing cost is low, and heat utilization efficiency is high.
The technical solution of the utility model is:A kind of high efficiency burnt gas direct-combustion boiler, including body of heater, neat gas burner, stove Water inlet pipe and outlet pipe are connected on body, combuster is connected on the neat gas burner, and combustion chamber is placed in body of heater Inside, combustion chamber top connect combustor exit by inverted-loop tube;A time water net of horizontal direction is fixed with the body of heater With two time water nets, wherein underlying two time waters net is not less than combustor exit;Spray is connected with the water inlet pipe Head.
The combustion chamber is cylindrical shape, and combustor exit is located above the water surface.
Outlet flue is provided with above the body of heater.
The utility model has the advantages that:Due to taking such scheme, combuster built in boiler, combustion chamber is put In in water, water can be heated by barrel;The flame sprayed by combustor exit can be heated directly to water;Returned on and Flue gas successively to drenching lower water progress heat exchange by two cloth networks of rivers and spray head the heat of flue gas can be made fully to be inhaled by water Receive, greatly reduce the flue-gas temperature of outlet flue, improve the thermal efficiency of boiler.And the boiler structure is simple, manufacturing process Simply, cost is low, free from environmental pollution.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of a time water net.
1- combustion chambers in figure, 2- combustor exits, 3- outlet pipes, the time water nets of 4- bis-, the time water nets of 5- mono-, 6- water inlets Pipe, 7- spray heads, 8- smoke-boxes, 9- outlet flues, 10- bodies of heater, 11- neat gas burners.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Fig. 1, Fig. 2, a kind of high efficiency burnt gas direct-combustion boiler, including body of heater 10, neat gas burner 11, on body of heater 10 Water inlet pipe 6 and outlet pipe 3 are connected to, wherein water inlet pipe 6 is located at top, and outlet pipe 3 is located at bottom.The combustion of natural gas Combuster 1 is connected on device 11, and combustion chamber 1 is cylindrical shape, is placed in inside body of heater 10, the top of combustion chamber 1 is connected by inverted-loop tube Connect combustor exit 2.The time water net 5 and two time water nets 4 of horizontal direction, the cloth network of rivers are fixed with the body of heater 10 On be uniformly densely covered with aperture, wherein the height of underlying two time waters net 4 is not less than combustor exit 2, and combustion chamber Outlet 2 is above the water surface.Spray head 7 is connected with the water inlet pipe 6.The top of water inlet pipe 6 is provided with cigarette in the body of heater 10 Room 8, outlet flue 9 is provided with the body of heater at the top of smoke-box 8.
At work, after neat gas burner 11 is lighted, natural gas burns in combustion chamber 1, the periphery of heating combustion chamber 1 Water, while gas flame is sprayed downwards from combustor exit 2 and contacted with the water surface, and water is heated;Now flame bounce-back is upward, with Water contact under the leaching of two time water nets 4, water is heated;The water that flame and flue gas are continued up under being drenched with a time water net 5 contacts, Water continues to absorb the heat of flue gas;Flue gas continues up after a time water net 5 that to spray the water curtain formed by spray head 7 direct The heat of flue gas is absorbed, flue gas residual air enters smoke-box 8, discharged by outlet flue 9.
Water in this boiler, except the metal barrel heat transfer by combustion chamber 1, the flame also sprayed by combustor exit 2 with Water directly heats, then the water curtain for adding two time water nets and spray head 7 to be formed carries out heat exchange, the heat of flue gas is fully inhaled by water Receive, therefore the temperature of the flue gas of the discharge of outlet flue 9 can drop to 40oC-60oC, so as to significantly by original general boiler about 180oC Degree improves boiler thermal output, and the thermal efficiency than general gas fired-boiler improves 10%-12%.
