In China, industrial boiler is a kind of important thermal energy supply equipment in the national economy. Electric power, machinery, metallurgy, chemical industry, textile, paper making, food and other industries, as well as industrial and civil heating, all need boilers to supply a large amount of heat energy. Boiler uses the heat energy or other energy released by fuel combustion to heat the working medium (intermediate heat carrier) to a certain parameter. Due to the particularity of indust...
With the strong support of government policies, the elimination of boilers with high energy consumption and high pollution has been accelerated, which has further promoted the rapid development of the green heating boiler market. So what's the price of green heating boiler? How to choose the type? In this article, ZOZEN Boiler will introduce the price of green heating boilers in details.
In the face of extensive market demand, the price of raw materials has risen due to environment...
The first reason is unreasonable structural design.
In the operation of chain grate boiler, uneven distribution of short coal seams in grate, improper adjustment of coal feeder, unreasonable control of coal seams and poor regulation performance of air supply volume in air chamber will all lead to insufficient burning of coal.
The second reason is unreasonable setting of secondary air.
If the primary wind speed is too high, the air volume is too large, and the air rate is too large, the pulver...
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.
1. Enterprise qualification
Which manufacturer is good, enterprise qualification is the first. On the whole, enterprise qualification reflects the enterprise's personnel quality, technology and management level, engineering equipment, capital and benefit, contract management ability and other aspects. Genera...
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.
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.
The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preh...
Modular gas-fired boiler, according to the user's load and design needs, combines several independently operating module units into an integral boiler. By monitoring and calculating the changes of indoor and outdoor temperature and temperature of supply and return water, the computer automatic control system can control each level of modules, automatically adjust the number of modules to start and stop, make the output heat always match the actual required heat load, and ensure that each module ...
