factory directly vertical gas steam generator
In order to further standardize Xuzhou City, air pollution control construction and operation management, protecting and improving the quality of the environment, prevent environmental pollution, introduced the "Xuzhou City in 2019 the thermal power industry, air pollution control basic norms." For the raw fuel storage, handling, transportation, storage byproducts, transport, collecting and centralizing the flue gas treatment systems and other aspects of the essence of the specific requirements.
First, all coal-fired units desulfurization facilities required to install, in addition to coal-fired circulating fluidized bed boiler units to be installed denitration facilities, coal and biomass fuel units to be equipped with efficient dust removal facilities. Desulfurization, denitrification, dust removal device processing capabilities must meet the production needs, we must be able to maintain long-term stable operation, must be professional manufacturers design, produce qualified products. Exhaust pipe shall be provided with permanent sampling ports and in accordance with national and regulatory requirements related to the construction of Jiangsu Province.
Second, the boiler produces air pollutants must be in accordance with national standards and requirements related to Jiangsu Province, construction of flue gas collection systems and centralized purification facilities, flaring has been the implementation of "coal to gas," "dry FGD" and included in discontinued closure plan outside the coal boiler, and the rest are required to install the cooling and dehumidification systems, and to ensure proper operation.
ZG is one of biggest internal CFB boiler manufacturer in China, The internal CFB Boilers plants provided in a successful operation for many years in capacities ranging from 30 to 350 MWe. Steam generators with internal circulating fluidized bed (ICFB) combustion have found acceptance throughout the world over the past few years, in particular for power generation, but also as industrial CFB power plants and cogeneration CHP stations.
The basic configuration of the heat of the gas steam boiler steam boiler and service method is natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace released heated pot water, and allowed to vaporize into steam heat conversion equipment. Water in the pot is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the expansion of the water vapor inside limited dynamic pressure generated heat is formed as an energy source is widely used. Steam boiler fuel burn-up and to ensure that the flue gas outlet temperature was cooled to a safe value convection heating surface of the work; using the heat of the flue boiler feedwater heating, in order to reduce exhaust gas temperature, fuel economy and functions. Each factory directly vertical steam generator heating surface and joined together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. Gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. Water temperature should be close to the furnace temperature. Must regularly inspect the low water cutoff maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. Require periodic sewage operation, at least once a day, after the sewage drain valve should be checked because of possible contamination and leaks; if it must be excluded. When shutdown is not maintained while the steam pressure, the steam space of the boiler will produce negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened.
How boilers used in conjunction with other equipment and cleaning instructions: boiler water and fire tube What's the difference? Boiler and steam turbine and generator, how the relationship between the three? As well as, boiler cleaning time, how long it should be a relatively good? These are questions belonging to the boiler area, but also we want to know, so the following, a good answer to it, its details are as follows.
