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...
Before the technical communication, there is no way for any manufacturer to give an accurate figure about the price of oil-fired gas-fired steam boiler immediately.
The price of oil-fired steam boiler is mainly affected by the following factors:
1. Technical parameters such as tonnage, pressure, temperature and thermal efficiency
2. Specific system configuration and brand of the boiler
3. Manufacturing process of the boiler
4. The altitude of the area where the boiler is used
5. Freight, s...
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...
What is a large-scale steam boiler? Generally, large-scale steam boilers mainly refer to steam boilers over 75 tons. Large-scale steam boilers can be divided into oil-fired boilers, gas-fired boilers, coal-fired boilers and biomass-fired boilers according to fuel. At present, the number of large-scale steam boilers used in the industry is still relatively large, among which they are used in chemical industry, food industry, industrial and mining enterprises and building materials enterprises.
The fuel cost of 10 tph electric boiler: 7,100 kilowatt-hour is multiplied by the local industrial electricity unit price which is nearly 1 RMB, so we can get 1 RMB/kWh and the fuel cost is about 7,100 RMB per hour.
Gas-fired boiler products used in different industries will be different. With the increasingly stringent environmental protection policies issued by the state in recent years, gas-fired boilers are widely used in all walks of life. The quotation of different configurations of gas-fired boiler varies greatly, and the quotation of 3-ton gas-fired boiler does not have a fixed amount, because the quotation of 3-ton gas-fired boiler system is composed of boiler body price and auxiliary equipment pri...
Boiler output refers to the maximum continuous output of the boiler under rated parameters (pressure, temperature) and certain efficiency. For steam boilers, it is called rated evaporation, and the unit is tons/hour; For hot water boilers, it is called rated heat production, and the unit is MW.
What are the main factors affecting the output of gas-fired boilers? According to the analysis of ZOZEN Boiler engineers, there are many reasons for the insufficient output of gas-fired boilers,
...
Horizontal steam boiler structure
The horizontal internal combustion boiler has a large-diameter shell, in which a furnace is arranged, and the burner is placed in the furnace to form an internal combustion chamber. Both ends of the furnace are respectively connected with the front and rear tube plates, and the smoke tube is arranged between the front and rear tube plates, so there is no need for bricklaying walls outside the boiler. The structure is mainly composed of boiler shell, furnace, f...
