Hazard Ultra-low-load operation of the boiler mercadolibre 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.
Take you into the fast boiler mercadolibre - water level control technology (a): precise level control ensures that the boiler water to maintain homeostasis, party fast using multiple level protection system to ensure that the boiler water level fluctuations in the normal range, to ensure the safe operation of boilers . In this small series for the fast part of the water level party control technology for you to explain. 1, the electrical contact-type water level alarm protection
Thermal power plant installed capacity of heating load size, nature and other constraints, the scale of units to the main units of thermal power plant is much smaller than. Thermal power plant due to both power generation and heating,CFBC boiler mercadolibre capacity is greater than the same scale thermal power plant.The thermal power plant must put up more CFBC boiler with additional capacity than heat-engine plant,There are a large amount of water treatment.
Recently, Chuzhou City, Anhui Province issued a "Chuzhou Municipal People's Government on the issuance of Chuzhou City to win the Battle of the sky three-year action plan to implement the program," which raised more for coal-fired governance requirements, as follows.
First, the continued implementation of the total coal consumption control. As of 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's coal consumption to complete the tasks assigned by the provincial government; a new coal project implementation reduction of coal instead.
Second, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the residential electricity, industrial production, building heating heating, transportation, production of five major areas of agricultural implement "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for.
Third, carry out comprehensive improvement of the boiler. Increase efforts to eliminate small coal-fired boilers, to consolidate the results of coal-fired boilers eliminated. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour more coal-fired boilers (excluding boiler coal-fired plants) all meet the special emission limit requirements; 65 tons of steam per hour and above all coal-fired boilers and energy-efficient ultra-low emissions to complete the transformation. Low-nitrogen gas boiler substantially complete transformation; urban built-up area of ultra-low emission biomass boilers implement reform.
Fourth, increase the technological transformation efforts cogeneration units to speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.
Fifth, strengthen the bulk coal governance. Full implementation of the "Interim Measures for commercial coal quality management" and coal-fired boiler technology standard, good bulk coal use Survey, the development of bulk coal governance implementation. Expand the scope of urban high-pollution fuel combustion zone ban, and gradually extended to the outskirts of the urban area. Combustion zone ban prohibiting the use of high-polluting coal for fuel, the progressive realization of no coal rank. Daly promote quality and new coal stoves, improving combustion efficiency.
