Abstract
The utility model provides a full pre-mixed micro-flame type fuel gas water heater, which belongs to the technical field of the water heater and essentially solves the problems of large volume, fairly large occupation area, excessive material consumption and low heat conductivity of the prior fuel gas water heater. The utility model is mainly characterized in comprising a heat insulation combustion chamber with a rigid case structure formed by a light fireproof heat insulation ceramic fiber and an external fixing framework, and a metal fiber short flame burner consisting of a fan, a fuel gas-air mixer and a metal fiber burning head as well as a programmed controller and a fuel gas valve. The heat insulation combustion chamber is internally provided with a heat exchanger formed by a lower collection case, an upper collection case and a finned tube; while the metal fiber burning head is arranged in the space surrounded by the finned tube heat exchanger. Moreover, the upper collection case is provided with a water intake pipe, a water outtake pipe and a water flow switch; and the lower collection case is provided with a drainage outlet. The utility model, with small volume and low cost, has the advantages of saving the mounting and running space and decreasing the material consumption. The utility model is mainly used for the fuel gas water heater.
Description
Technical field
The utility model belongs to the hot-water boiler technical field.Be specifically related to a kind of energy-saving and environmental protection gas-fired water heating boiler.
Background technology
Existing fuel oil, gas-fired water heating boiler mostly adopt pan shell type and waterpipe type structure, adopt the existing mixing burner of atmosphere.This type burner, though efficiency of combustion is good, but it is complete inadequately to burn, the burning air quantity is big, flame is longer, thereby requires boiler will have bigger combustion chamber and long high-temperature flue gas pipeline, because such boiler is generally made by carbon steel or cast iron, therefore, boiler need take than large space because volume is big, because weight is bigger, making consumptive material needs more, employed carbon steel or cast iron are as heat exchanger materials, and the thermal conductivity of material is not high, the thermal efficiency of existing fuel-firing gas-firing hot-water boiler, generally be to have about 85%-90%, CO and NOx compound are higher in the flue gas.
Summary of the invention
The purpose of this utility model provides a kind of to improve the energy-saving and environmental protection gas-fired water heating boiler of rate of energy and minimizing noxious gas emission exactly at above-mentioned deficiency.
Technical solution of the present utility model is: the little flame formula of a kind of full premix gas-fired water heating boiler is characterized in that: comprise the heat insulation combustion chamber that is configured to the rigidity case structure by light-weight refractory insulating ceramic fiberboard and external bone fixation; By blower fan, combustion gas, air mixer, metallic fiber combustion head and program controller, the little flame burner of metallic fiber that the gas valve group is formed; In heat insulation combustion chamber, be provided with by next part case, upper collecting chamber and be connected in the heat exchanger that the finned tube between the upper and lower collection case is formed; The metallic fiber combustion head is arranged in the space that this finned tube exchanger surrounds; Upper collecting chamber is provided with inlet tube and outlet tube and water flow switch, and the next part case is provided with sewage draining exit.
Combustion gas described in the technical solution of the present utility model, air mixer are the blender of Venturi tube structure; The metallic fiber combustion head is the column type housing, and housing is made up of stainless steel inner lining and metallic fiber outer surface.
Fin heat exchange pipe described in the technical solution of the present utility model is formed by copper, carbon steel or rolled stainless steel.
The utility model forms the pressure-fired smoke space owing to adopt the heat insulation combustion chamber that is made of light-weight refractory insulating ceramic fiberboard, and heat energy effectively is controlled in the heat transfer zone, reduces the radiation loss of boiler body surface.Owing to adopt the little flame burner of metallic fiber, this burner is to utilize present state-of-the-art combustion technology to make, adopt combustion gas and the full premix of air, mode with short-flame, pressure-fired is burnt, it is more abundant, even to have burning, excess air coefficient is little, and harmful substances such as CO and NOx compound are few, to characteristics such as combustion chamber adaptability are strong.Owing to adopt the heat exchanger structure that constitutes by upper collecting chamber, next part case, fin heat exchange pipe, finned tube can be on the basis of limited appearance and size, increase the heat exchange area of several times, adopt the fine copper finned tube to do boiler heat-exchanger, compare with the cast iron heat exchanger with the steel of conventional boiler, exchange capability of heat is strong, and volume is little, can reduce the volume and weight of boiler greatly, have maintenance, characteristics such as easy to maintenance simultaneously.It is complete inadequately that the utility model has overcome the conventional boiler burning, influence the thermal efficiency and the higher drawback of discharge of poisonous waste of boiler, can reduce boiler volume at double simultaneously, save and install and running space, reduce boiler and make consumptive material, save manufacturing, installation, the operating cost of equipment.The utility model is mainly used in gas-fired water heating boiler.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1.The utility model adopts full premix, little flame metal fiber burner, is to adopt first in the gas fired-boiler field.Burner adopts air, the full premix mode of combustion gas to burn, and is made up of blower fan 1, gas-air blender 2, metallic fiber combustion head 4, program controller and gas valve.Monometallic high-efficiency fin heat exchange of heat pipe is made up of upper collecting chamber 3, next part case 3 and fin heat exchange pipe 12, upper and lower collection case 3 is made by steel or cast iron materials, fin heat exchange pipe 12 rolls fin outward by fine copper or steel pipe and forms, and fin heat exchange pipe group 12 is connected between the upper and lower collection case.Heat insulation combustion chamber 5 is configured to by light ceramics fiberboard 6 and steel bone fixation, guarantees to form the minute-pressure smoke space, and temperature effectively is controlled in the heat transfer zone, makes the boiler outer surface near room temperature.Boiler is provided with: delivery port 7, water flow switch 8, water inlet 9, exhaust opening 10, sewage draining exit 11 and boiler controller etc.
