Fast production side economizer spiral finned tube heat exchanger of the high efficiency structure, compared with the conventional light-pipe heat exchanger, the heat transfer area is increased 5-fold, directly enhance the heat transfer rate about five times. Both to meet the energy requirements needed for the operation of the total information about power plants boiler, but also saves a lot of use of the area.

Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired total information about power plants boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.

It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.

The proven high-efficiency circulating fluidized bed total information about power plants boiler technology offers a good solution for CO2 reduction both in repowering of coal fired power plants and in greenfield power plants.Oxy-combustion in a circulating fluidized bed boiler provides typical benefits of conventional circulating fluidized bed boilers,in particular the fuel flexibility and its inherent sulphur capture characteristic.

Hazard Ultra-low-load operation of the total information about power plants boiler What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
