The water boiler mainly solves the problems of large volume, high body surface temperature, great space occupied, more materials consumed and not high heat conductivity lying in the prior fuel gas water boiler. The water boiler is mainly characterized in that the water boiler comprises a metal fiber short flame burner consisting of a fan, a fuel gas and air mixer, a metal fiber combustion head, a program controller and a fuel gas valve block, and a heat exchanger consisting of a upper header tank, a lower header tank, and a finned tube connected between the upper and lower header tanks; the upper header tank has an atmosphere communication pipe, a water inlet pipe, a water outlet pipe and a water flow switch, and the lower header tank has a pollution discharge port; water pipes are arranged at intervals on the outer circumference of the upper and lower header tanks, steel membranes are arranged between the water pipes, and the steel membranes and the water pipes form a membrane wall of a thermal insulation barrel type combustion chamber. The water boiler is characterized by small volume, installation and operation space saving, boiler manufacturing materials reduction and low cost. The water boiler is mainly used as a fuel gas water boiler.
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.In addition, the shell temperature of existing fuel oil, gas-fired water heating boiler is higher, thereby has influenced the further raising of boiler thermal output.
Summary of the invention
The purpose of this utility model provides a kind of to improve the little flame formula of the full premix of the energy-saving and environmental protection type gas-fired water heating boiler of rate of energy and the shell temperature that reduces noxious gas emission, reduction boiler 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 comprises by blower fan combustion gas, air mixer, metallic fiber combustion head and program controller, the metallic fiber short flame burner that the gas valve group is formed; By upper and lower collection case 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 atmospheric communicating pipe, inlet tube and outlet tube and water flow switch, and the next part case is provided with sewage draining exit; It is characterized in that: be interval with water pipe at upper and lower collection case circumferential periphery, be provided with steel diaphragm between this water pipe, form the fin panel casing of heat insulation cartridge type combustion chamber together.
Fin panel casing described in the technical solution of the present utility model is welded by metal tube and metallic plate.
Air mixer described in the technical solution of the present utility model is 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 is owing to adopt the fin panel casing that is made of water pipe, steel diaphragm, this fin panel casing and upper and lower collection case are formed heat insulation cartridge type combustion chamber, form the pressure-fired smoke space, effectively be controlled at heat energy in the heat transfer zone, reduce the radiation loss of boiler body surface, help the further raising of boiler thermal output.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 of boiler, higher and the higher drawback of shell temperature boiler of discharge of poisonous waste, simultaneously can reduce boiler volume at double, 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.
