Works steam boiler steam boiler structural characteristics: 1. Heat generated in combustion of coal is first absorbed water wall heat transfer by radiation, boiling off the water wall, a large amount of steam (excluding DC furnace) inside the drum, separated saturated steam enters the superheater, and by radiation and convection manner continue to absorb top horizontal flue heat and smoke flue tail, the superheated steam to reach the required operating temperature. Steam boilers for power generation is usually provided with a reheater, to a high pressure steam heated cylinders. Reheat steam reheaters into the low-pressure cylinder continue to work to generate electricity. 2. pulverized coal work, the location of the center of the flame will affect evaporation. Generally, when the center of the flame is low, a large amount of evaporation, and when the high center of the flame, a small amount of evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Normally, when the center of the flame is low, superheated steam, in particular steam reheating temperature to be low, and the temperature of the superheated steam is high. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined. Steam boiler structural characteristics: 1, the steam boiler body welding: the main welding using submerged arc welding technology advanced, to ensure the welding quality. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. All welds are main as required "safety Technology supervision standard", 100% ray detection electrode according to the eligibility criteria Ⅱ. 2 is a horizontal steam boiler combustion all wet back three-loop structure. 3. The steam boiler front smoke box is sealed asbestos refractory material made of graphite. The reliable seal, ensures that no leakage of steam boiler flue gas at positive pressure conditions. 4. Thread flue: industrial steam generator alibaba secondary regenerator flue threaded convection heating surface, contribute to the efficient heat transfer. Enhanced heat transfer, thermal efficiency of the steam boiler, a single light pipe threaded pipe or 2.4. When the fluid flows in the tube, the flow rate of the fluid near the wall is low, the fluid on the wall boundary layer is called. In several of the flue gas duct in the outer aqueous series resistance, the maximum thermal boundary layer, but the boundary layer is very thin, as long as the boundary layer is slightly perturbed, such as by pressing on a common wall of the boss, the thermal resistance will be greatly reduced, while an effective method which is threaded pipe. 5. To make the system more energy efficient, using a continuously adjustable water supply, avoiding frequent start the pump. Between the second and the third pivot smoke tubes have a broad space for water, in order to ensure natural circulation of water in the pot.
10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.
"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.
In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).
It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration.
