Parameters and functions of gas-fired hot water boiler

Heating and hot water supply are problems that many families and collective units need to solve. Generally, a single family will rely on the collective heating system for heating, while the supply of hot water depends on various forms of water heaters. However, general collective companies or units will use large boilers to realize the simultaneous supply of heating and hot water. Boilers are widely used in various occasions as equipment for heating or providing hot water, but they are generally used for collective heating or providing hot water. There are many kinds of boilers, some burning coal, others burning natural gas, gas or liquefied gas. Due to the enhanced awareness of energy conservation and environmental protection in the country this year, the number of coal-fired boilers has gradually decreased, while the number of gas-fired boilers has increased. So, do you know anything about gas boilers? Know anything about gas-fired hot water boilers? The following rabbit will introduce the parameters of gas-fired hot water boiler to everyone.

I. About gas-fired hot water boilers

Gas-fired hot water boiler is a kind of gas-fired boiler, which is mainly used to supply hot water, and it is also a hot water supply equipment encouraged by the state in recent years. Gas-fired hot water boilers can use combustible gases such as natural gas, coal gas, liquefied gas and biogas as fuel. Because these combustible gases are relatively clean, and they are energy sources with high combustion efficiency and low price, gas-fired hot water boilers have become hot water supply equipment that has attracted much attention because of their high efficiency, energy saving, environmental protection and economy.

Literally, gas-fired hot water boilers provide hot water, but gas-fired hot water boilers can not only provide heating or hot water alone, but also provide hot water at the same time. As long as a heat exchanger is installed in the equipment, a pot can be used for both purposes. Burner and boiler controller are the two most important parts of gas-fired hot water boiler, in which the burner is mainly responsible for heating water and the controller controls the operation of the whole boiler. According to different classification basis, gas-fired hot water boilers can be divided into many different types. Their main differences are reflected in structure, fuel use, use and structure. Although different, the basic working principle is basically the same.

Second, the technical parameters of gas-fired hot water boiler

Before buying and using the gas-fired hot water boiler, we need to know something about its performance, functions and so on, and to understand these, we must start to understand its technical parameters.

How to use gas-fired hot water boiler

1, domestic gas boiler-condensing furnace

The burner of the condensing boiler burns downwards, so the tail gas can be reused. It is beneficial to the recovery of flue gas heat and can reduce the loss of direct energy. Originally, after natural gas was burned, the exhaust gas temperature was very high. If discharged directly from the flue, a lot of heat will be lost in the atmosphere, which is not only harmful to the atmosphere, but also a waste of energy.

2. Domestic gas-fired boiler-casing boiler

When the casing boiler is used for floor heating and domestic water, the heating part is at the top of the furnace, which will definitely affect the service life of the casing. Therefore, the quality of the double-tube boiler is also the lowest.

3. Domestic gas-fired boiler-plate boiler

When the plate-changing boiler takes domestic water, the boiler is specially equipped with a heat exchange plate, and the heating waterway is cut off by switching the valve, so that the heated hot water forms a small circulation in the boiler, and the heat is changed into domestic water through the plate-changing. This will keep the water hot for a long time.

Domestic gas-fired boilers are all water and electricity integrated equipment, and ensuring safe use means ensuring our life safety. Many domestic gas boilers will have accidents only after incorrect operation, so correct operation is very important. The following will explain the correct use of domestic gas boilers for you.

1, it is necessary to ensure the smooth suction and exhaust of boiler flue. When the boiler is working, fresh air is sucked in from the outer tube and combustion waste gas is discharged from the inner tube. Therefore, when decorating a closed balcony or moving a machine, the owner must extend the suction port and exhaust port of the smoke pipe out of the window, and must not seal it indoors or use a single-core pipe, otherwise the boiler will easily suck back exhaust gas when burning, resulting in insufficient oxygen supply during burning, which will easily lead to boiler explosion, ignition failure or frequent start-up, leaving hidden dangers for the safety of life and property.

2. Gas-fired boilers will emit a certain amount of waste gas, but they are also loved by ordinary people because of their economic applicability and high cost performance.

3. When the wall-hung boiler is working, the temperature of the heating, hot water outlet pipe and smoke pipe at the bottom is high, so it is forbidden to touch it to avoid scalding.

Note: It is best for professionals to disassemble and assemble the smoke pipe, so as to avoid the untidy seal at the interface of the smoke pipe and cause accidents.

The above are the parameters of the gas-fired hot water boiler that Bunny introduced to you, hoping to help you. There are many kinds of gas-fired hot water boilers, and there are many models of the same gas-fired hot water boiler. The technical parameters of different models of each variety will be different, but the basic technical parameters are basically the same.
