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...
Industrial boiler is a kind of energy equipment widely used in production. The energy equipment is a boiler system composed of boiler body, combustion engine, fan, motor, etc. If you want to operate the boiler system correctly, it involves all aspects.
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...
Gas-fired boiler is a kind of thermal equipment that uses the thermal energy released by fuel combustion or other thermal energy to heat the medium to the rated temperature. With the strict environmental protection, gas-fired boilers are widely used in power generation, heating, factory processing and so on. Boiler thermal power refers to the continuous heat production per unit time of hot water boiler at rated parameters, rated flow, designed fuel and guaranteed efficiency. So how to convert th...
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 principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
The boiler needs to blow off every day, and it is advisable to reduce the blowdown to below the boiler water level every time.
The boiler water level meter can record the boiler water level in detail, and the water level has a great influence on the boiler, so we should ensure that the boiler water level is within the normal range.
When the gas-fired boiler is running, there will be pressure inside, which can provide sufficient power for all kinds of production equipment. However, if the press...
1. The defective parts in the last inspection.
2. Whether there are cracks and corrosion on the inner and outer surfaces of boiler pressure components, especially on openings, welds, edges and so on.
3. Whether the pipe wall is worn or corroded.
4. Whether there is any crack, fracture or corrosion at the brace of the boiler and the joint with the pulled element.
5. Whether the expansion port is tight, and whether there is annular crack in the expanded part of the pipe end.
6. Whether the ri...
