Boiler safety accessories mainly refer to pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve and other accessories. These accessories are very important for the safe operation of the boiler, especially the pressure gauge, water level gauge and safety valve, which are the basic accessories to ensure the safe operation of the boiler. Therefore, they are usually called the three safety accessories of industrial boilers. Knowing the three safety accessories of boiler is...
Condensing boiler and non-condensing boiler are two main types of gas-fired boilers on the market at present. A correct understanding of the difference between condensing boiler and non-condensing boiler can help you choose a reasonable type. Before introducing the difference between them, it is necessary to introduce the principles of condensing boiler and non-condensing boiler.
Introduction of working principle of non-condensing boiler
Non-condensing boiler is a kind of heat energy c...
Evaporation tube bundle and water cooling tube panel are two important heating surfaces of the boiler, which are all arranged inside the boiler, so it is not easy to see them intuitively.
Boiler evaporation tube bundle
Evaporation tube bundle mainly absorbs convection heat transfer in small and medium-sized boilers. Generally, it is a bundle of dense staggered piping systems consisting of ascending pipes and descending pipes that connect the upper and lower drums. The heat load of the ...
Low-carbon condensing gas boiler takes clean energy natural gas as fuel, and uses high-efficiency flue gas condensation waste heat recovery device to absorb sensible heat and latent heat released by steam condensation in the tail of the boiler, so as to achieve the purpose of improving boiler thermal efficiency and saving energy, thereby reducing carbon emissions.
Low-carbon gas-fired boiler recovers the energy from the hot flue gas (generally around 140℃) emitted by the boiler through ...
Coal-fired boiler economizer, as its name implies, is a boiler device to save energy. The structure of coal-fired boiler economizer is relatively simple, which is mainly composed of all stainless steel 304 frame and stainless steel spiral finned tubes, all of which are arranged in a certain order.
According to the power, size and price of the boiler, the boiler economizer adopts different materials such as stainless steel and ND steel. According to the medium, coal-fired boiler economizer is ma...
The boiler is composed of membrane wall, tube bundle, steam drum, furnace wall, header and other components, among which the boiler steam drum is a very important pressure component.
Boiler steam drum, also known as drum, is an important pressure component in natural circulation boiler and forced circulation boiler. It is a cylindrical pressure vessel used for steam-water separation and steam purification in water tube boiler, which forms a water circulation loop and stores boiler water...
The boiler economizer is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It absorbs the heat of the high-temperature flue gas to heat the boiler feed water, reduces the temperature of the exhaust gas of the boiler, saves energy and improves the thermal efficiency of the boiler. Therefore, when using boilers, it is very important to master the correct treatment method of boiler economizer tube burst.
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
