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.
Combustion system: The combustion system of coal-fired thermal oil heater includes base, grate, furnace, etc. The combustion system of oil/gas heat-conducting oil boiler includes furnace, burner, ignition device, etc.
Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
Control system: complete with boiler control box.
Air-smoke system: refers to the system composed of flue gas and air generated by combustion, mainly including induced draft fans...
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...
1) The insufficient heating surface. In the process of retrofit design or improvement, increase the heating surface.
2) The particle size of the fuel is large, the screening characteristics do not meet the requirements, the material concentration in the suspension section is low, and the heat transfer coefficient is small, which makes the output unable to go up, or shows that the bed temperature is high and coal cannot be added. The solution is to improve the fuel preparation system and control...
The boiler in the bathhouse provides hot water for bathing and heating, and it is an essential product in bathhouses. Generally, it is hot water boiler. With the elimination and banning of coal-fired boilers, many users choose energy-saving and environment-friendly gas-fired boilers. Then how much is a suitable gas-fired boiler?
First of all, we have to determine the boiler plan. Bathhouses mainly need to supply hot water and winter heating all the year round. There are two main options: one se...
