Different combustion modes are the core difference between fluidized bed boiler and common boiler.
Fluidized bed boiler adopts fluidized combustion mode. After the fuel is crushed to a proper particle size by a crusher, it is fed from the upper part of the air distribution plate of the combustion chamber by a coal feeder, mixed with the hot boiling materials in the combustion chamber, heated rapidly, and the fuel quickly catches fire and burns. Under the action of high air velocity, a large num...
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...
Boiler heat supply refers to the continuous heat production per unit time when the rated parameters, rated flow, designed fuel and efficiency are guaranteed. There are many ways to express the boiler heat supply, and there are certain conversion standards.
Conversion between heat supply units: 1t/h = 0.7mw = 600,000 kcal/h =720KW
According to the conversion standard, a 5-ton boiler is also a 3.5MW boiler. Therefore, for the users who need 3 million kcal boilers, we recommend WN...
The boiler chimney is one of the essential facilities in the process of building a gas boiler room. Its main function is to provide ventilation for the hot flue gas or smoke emitted by the boiler. Usually, when making the chimney of gas boiler, choose the vertical structure as much as possible to ensure the gas flow smoothly, and the sucked air enters the so-called chimney combustion or stack effect.
Because gas-fired hot water heating boiler is used for central heating, after the boiler is ignited, it needs to go through a series of processes such as furnace heating, low-temperature operation, heat exchange and so on, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.
Many people will consider the heating efficiency and heating area when choosing and using boiler equipment. In fact, how many square meters a ton of hot water boiler can heat has a certain relationship with the type and capacity of the equipment.
Generally speaking, the heat to be absorbed by 1kg of water is 1kcal for every 1℃ increase, it is concluded that the heat supply of 1 ton (0.7MW) boiler is 600,000 kcal. Therefore, how much boiler is needed to heat 20 tons of water from 15℃ to 40℃ for ...
Chain grate boiler is a very mature boiler type, which has the characteristics of simple operation and management and easy mastering, and is widely used in various industries.
