The stove is a household appliance, has wide application, can be used for heating and cooking, and the household boiler is a civil life boiler for household heating or bathing, has small volume and low energy consumption, and is typically characterized by being suitable for household use. The domestic boiler mainly adopts two types of wall-mounted boilers and floor boilers. The furnace type means that the types of furnaces can be generally classified into four types according to the type of fuel,

oil burners, furnaces in which fuel is pressurized, are typically provided with a pumping device to pump air into the fuel bottle, increasing the pressure in the bottle, and thereby feeding fuel into the burner. The multi-purpose stove can even be used for various fuels, such as gasoline, kerosene and stain removing oil. If gasoline is selected as the fuel, it is preferable to use low octane number gasoline, and more preferably unleaded gasoline. The oil stove can cook food quickly, is expensive, has high fuel efficiency, requires time for familiar operation, is suitable for high-altitude environment, requires time for preheating the stove, can adapt to various environments, needs to be careful in operation of some stoves, has lower fuel cost, and can generate toxic substances when gasoline and kerosene are combusted.

At present, a plurality of styles can be selected, and when the style is selected, the furnace end is determined to be provided with the sealing ring which can be tightly combined with the gas tank, so that the gas can not leak. The gas is of propane, butane, isobutane and other types, common mountain gas tanks are mostly of a mixed type, combustion can be stably and continuously helped, the gas tanks can still be operated at minus 1 ℃, the gas tanks are easy to control the duration of fire, fuel is not easy to obtain, the gas tanks are high in safety and simple in structure, the gas tanks need to be preheated at minus temperature, the gas tanks are easy to operate, sealing rings are checked if necessary, the combustion is quick and efficient, the gas tanks are easily influenced in strong wind, the gas tanks can still be used in a high altitude environment, empty tanks can not be recycled, the fuel does not need a pressurized furnace, methanol and alcohol are generally used as the fuel, and the fuel is generally in a liquid state during. The method has the advantages of easy operation, low flame temperature, low thermal efficiency, high safety, more fuel requirement, high cost, stable fuel, difficult influence of wind potential, transparent flame and difficult identification.

The wall-mounted gas boiler is used in common houses and apartments, uses natural gas, liquefied gas or coal gas as fuel, and can provide both heating and sufficient domestic hot water for people. The wall-mounted boiler has the power of 18-35 KW generally, has double functions of heating and domestic hot water, needs to consider the heating use area and the consumption of hot water during selection and matching, usually 100W/square meter is selected for heating, but common families need to ensure that one shower and one kitchen hot water faucet are used simultaneously in winter, so 24KW is most suitable; if the house is large or more than three hot water points are used at the same time, the specification of the house is larger, but whether the flow of the gas meter can ensure that the use of the kitchen range is not influenced when the boiler operates or not is also considered, so that the boiler is not recommended to be selected to be too large. The wall-mounted boiler integrates various main components in a heating system, such as a circulating pump, a closed expansion water tank, a safety valve, an exhaust valve and the like; besides, the safety protection device and the automatic control device are also provided, such as a wind pressure switch and an overheat protection.
