The characteristics of internal circulating fluidized bed boiler
The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:
1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.
2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;
3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;
4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;
5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;
6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.
7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.
Gas and coal-fired easy operation industrial coal fired steam boiler coal steam boiler at any time there is any good compared to the country more and more attention to environmental protection, coal-fired steam boiler has been a great blow, and relatively gas steam boiler by many users of all ages, in recent years the country also vigorously promote the use of gas-fired boiler, then what are the benefits of gas compared with coal-fired steam boiler steam boiler it? And today we work together to explore. Gas-fired steam boilers and coal-fired steam boilers on the market each accounted for half of the country, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of coal-fired boilers, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, than the price of coal-fired boiler gas boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more coal-fired steam boilers, so the boiler room construction funds have more. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The coal-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than burning coal per hour to be much more. 4. environmental costs: in the need to protect the environment, review the current coal-fired boiler more strict. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used.
Effect of boiler fine coal combustion boiler operating principle is to use thermal energy or heat in industrial post fuel released by combustion is transferred to the water in the container, the temperature or pressure of the water reaches a certain desired steam heating equipment. Many people will feel that coal-fired boiler more detailed the better, but is it really? From a combustion point of view, the finer coal particles more easily form a good mixing with the air, the more complete the combustion. But the coal particles too small, for boilers, milling power consumption will be greatly increased. Industrial boiler, the coal into the furnace too small, there will be the following questions: 1, coal leakage losses, etc. from grate gap increased. 2, boiler grate to be at full speed, power consumption increases. 3, fly ash, fuel loss increases. 4, a coal burning ember i.e., unstable combustion, furnace volume heat load difficult to sustain stable. So the boiler when using fine particles of coal, coal is subject to how much water, raw coal water, play groups and then into the furnace. If the burning coal of 8 to 12h before the water, so that the penetration of moisture into the interior of the coal particles is better. Water vapor produced is moistened triatomic gases, flue gas can strengthen radiation, facilitate ignition, exhaust and reduce heat loss
The onset of winter, is located in Jilin Province Dongliao has entered the heating season. Recently, the Market Authority early planning, meticulous planning, to increase the safety supervision of the winter heating boiler, ensure the safe operation of heating boilers, curb the occurrence of all kinds of accidents, to protect people's safety, warm through the winter.
Market Authority set up a special investigation and remediation work organization boilers, special equipment to carry out self-examination from the security situation boiler heating units used to implement the main responsibility for the use of special equipment unit; simultaneous information collection boiler safety hazards, analyzing, improving risk control mechanism, proper risk monitoring, early warning and disposal of systematic risks and hazards should be reported promptly and truthfully; submit the initiative "special equipment unit security risk self-examination and self-change information tables to special equipment safety supervision organs ", and accept the supervision and inspection of the market, ensure that the boiler control risks effectively.
As of now, the council inspected the heating boiler unit 13, heating boilers and other special equipment to check 18 times, investigation and security risks 3 onwards, has been completely removed. The bureau said the next phase will further increase the safety and inspection of heating boilers, heating boiler unit supervise the implementation of the safety requirements, ensure that the heating boiler and other special equipment safe and stable operation. While strengthening the duty to timely and properly handle emergencies, a comprehensive good winter heating special equipment emergency security work.
