Abstract

The utility model relates to a fuel gas warming furnace which is provided with an interlayered water jacket box body, a gas discharging connector and a water return pipe are respectively arranged at the top and the bottom, a fuel gas heater is arranged on the lower part of in the box body, a semicircular hollow cover shell shaped heat exchanger is arranged above the heater, a water inlet opening of the heat exchanger is communicated with the inner layer of the water jacket box body through a water delivery pipe, and a water outlet opening is threaded out of the wall layer of the water jacket box body through a hot water delivery pipe. After the fuel gas heater is ignited, the heat exchanger widely absorbs the heat, the working medium water in the casing cavity of the heat exchanger quickly rises to above 60 degrees and immediately discharges out of the hot water delivery pipe and enters into a heating circulation system, finally the function that the room temperature achieves the warming demand is realized, and the air in the pipeline is automatically discharged along the gas discharging connector. The utility model has the advantages of compact structure, convenience for installation, low cost, high thermal efficiency, and good environmental protection performance, and the product is suitable to be installed and used in small work places and families without central heating.

Description

The economical gas heating stove

Affiliated technical field

The utility model belongs to civilian heating stove and accessory technical field, relates to a kind of gas heating stove that is applicable to minimized office place and family's heating.

Background technology

Many no central heating area and vast rural area in China cities and towns, for a long time, there are considerable unit and family to warm oneself by the mode that coal furnace (being native heating installation) is installed, defectives such as the thermal efficiency is low because coal furnace exists, poor stability, structure clumsiness, operation inconvenience, all brought many worries for user's real work and life, furthermore coal furnace is seriously polluted, there is great destruction in socio-ecological environment, thereby it requires to be limited always with repeating injunctions in recent years for relevant government department." enforcement of engineerings such as West-east Gas, " extra large gas disembarkation " and various circles of society are to the pay attention to day by day of environmental requirement; adopt to have natural gas and oil liquefied gas goods cheap, efficient, environmental-protecting performance and replace coal-fired as the warming resource; become imperative act undoubtedly, and the gas heating stove tool is also just under this overall situation and a kind of very promising product of releasing along with country.Known in the market gas heating stove tool all is external wall-hanging constructed products of producing basically, the combustion system more complicated of this class stove and accessory, gas quantity is big, cost an arm and a leg and be unfavorable for environmental protection, thereby its product still fails to be admitted by domestic users so far.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned deficiency of known technology product, trigger from energy-conserving and environment-protective and ordinary people ability to shoulder economically angle, provide a kind of compact conformation, easy for installation, cost is low, the thermal efficiency is high and the economical gas heating stove of good environmental protection.

Be used to realize that the technical solution of foregoing invention purpose is such: the economical gas heating stove that is provided has an intercalated water sleeve casing of being made and had return pipe by the sheet metal weldering, bottom in casing is provided with combustion heater, above heater, be provided with a semicircle hollow cover hull shape heat exchanger, have a water inlet and a delivery port on the housing of said heat exchanger, its water inlet is communicated with water jacket casing internal layer by water-supply-pipe, its delivery port passes from water jacket casing parietal layer by the hot water delivery pipe, is provided with an exhaust joint that communicates with the water jacket internal layer on the casing top.When the utility model was installed, casing return pipe and heat exchanger hot water water-supply-pipe were connected contain working-medium water in whole heating pipe network with the return pipe and the upper hose of room heating system respectively.In the use, make the combustion heater igniting by automatic lighting valve, the heat exchanger that is positioned on the heater extensively absorbs heat thereupon, in very short time, working-medium water in the shell heat exchanger chamber is warmed up to more than 60 ℃ and is immediately discharged by the hot water water-supply-pipe, enter the heating installation circulatory system, the final realization makes room temperature reach the effect of heating requirement, and the air in the pipeline is then discharged automatically with exhaust joint.

Description of drawings

Accompanying drawing is the operation principle schematic diagram of a specific embodiment structure of the utility model.

The specific embodiment

As shown in the figure, economical gas heating stove described in the utility model comprises members such as shell, combustion heater (igniting stone or metal plate for standing a stove on as a precaution against fire) 2, heat exchanger 4, water-filled pipe and smoke exhaust pipe 6.Wherein: shell is made of the totally-enclosed intercalated water sleeve casing 1 with sheet metal weldering system, is respectively equipped with exhaust joint 7 and return pipe 3 at casing 1 top and bottom; Combustion heater 2 is located at the bottom of the combustion chamber of furnace body that is surrounded by casing 1, has safety guard on this heater, occurs as deficiency of air or other fault in the work, and heater can be died in 2 seconds automatically, can not damage; The heat exchanger 4 that is located at the top of combustion heater 2 is a helper spring system semicircle hollow cover hull shape member, is respectively equipped with water inlet and delivery port in this member bottom and top; The water-filled pipe of addressing in the utility model comprises a water-supply-pipe 9 and a hot water delivery pipe 5, said water-supply-pipe 9 is serially connected between water jacket cabinets cavity and the heat exchanger water inlet, said hot water delivery pipe's a end is connected with the heat exchanger delivery port, and the other end then passes and be external to room heating system upper hose by water jacket casing shell wall; Smoke exhaust pipe 6 stretches in the combustion chamber of furnace body from passing the water jacket box body wall outside to inside, and the small amount of exhaust gas after combustion heater 2 work will be discharged outdoor with smoke exhaust pipe 6.Concrete enforcement in the structure, in order to strengthen heating effect, the pipeline working method can be designed to gravity flow and forced circulation dual mode, promptly attaching in parallel has a circulating pump water-supply-pipe 8 on heat exchanger inlets water-supply-pipe 9, so just can make heating stove can take corresponding heating system according to the concrete area situation in house in actual applications: to area at 50 square metres with interior room, basically the flow process mode of utilization gravity flow just can reach desirable temperature in 20 minutes; For the house of area greater than 50 square metres, then can open circulating pump system and circulate by force, in the same time, also can make the temperature that reaches desirable in the room like this.

Compared with prior art, compact conformation of the present utility model, easy for installation, good environmental protection are owing to adopt With having the heat exchanger device of special shape, absorbing heat is fast, the thermal source utilization is abundant, the thermal efficiency is high, consumption Narrow-minded, thereby energy savings and reduce the heating cost effectively, in addition owing to be provided with automatically at body of heater The devices such as safeguard protection, automatic vent, automatic switch and hot water circulating pump, product also have high safety, Force heat supply, easy and simple to handle, the advantage such as applicability is wide.
