automatic lignite coal hot water boiler
Steam boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).
Condensing gas boiler with coal-fired boilers What are the differences? Some may have which is not very clear to distinguish condensing gas boiler with coal-fired boilers, here we look at their specific differences, 1. The circulating fluidized bed combustion coal-fired boilers are coal by crushing equipment , by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers is relatively gas boiler, SO3, NOx is much less. 3. Ventilation general negative pressure combustion coal burning boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Micro-condensing gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion furnace flue wall and running flue outlet air coefficient can be 1.05-1.2.4 fuel combustion safety explosion-fired boilers, furnace explosion hazard unlikely to occur. The condensing gas boilers in the explosive concentration limits encountered fire will explode. More dangerous. The boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to load difficult boiler operating parameters. And condensing gas boiler is less impact on the factors may be adjusted according to the size of the burner valve load, easy to achieve automatic control.
Fangkuai boilers take you to know that horizontal steam boilers are usually used in a very large number of models, depending on the fuel, the working principle, and the different structures of the boiler itself, which are divided into many different types of boilers, and they are divided into many different types, depending on the fuel, the working principle, and the different structure of the boiler itself. In the case of steam boilers, there are also ordinary boilers and steam boilers, for this horizontal steam boiler, its characteristics are not the same. The boiler arch is made of refractory concrete. The rear arch is low and long, so it burns well. The two-wing flue and side wall brick are made of refractory brick. Boiler front wall, rear wall using universal refractory brick. The air distribution of the grate is reasonable, and the combustion chamber is larger. The applicability of coal is strong. Suitable for all kinds of bituminous coal or anthracite, mixed coal. It burns well. Because the high temperature flue gas first enters the settling chamber and then into the two-wing flue from both sides, and the front smoke box, so the smoke elimination and dust removal effect is good. The water circulation is simple, the compressed parts have reasonable structure and can run safely under the condition of ensuring water quality. The burning equipment is a fast-loading grate. The burning equipment is manufactured and installed in the factory and installed directly on the ground after transportation to the site. It has the advantages of reasonable structure, compact structure and low steel consumption, which makes the boiler's performance, weight and structure size obviously advanced compared with the domestic products with the same capacity. The boiler type is horizontal fast loading water Fire tube boiler, working fluid natural circulation. The boiler heat transfer system consists of a boiler drum, a left and right header, and a water wall. The heating surface is mainly composed of a furnace water wall, a part of the boiler drum and a convection tube bundle in the boiler tube.
Coal-fired boilers, fuel shots are fired, coal in the combustion chamber after the combustion heat release, the heating medium water or other organic heat (e.g., heat transfer oil, etc.) heated to a temperature (or pressure) of the thermal power plant. Coal is our energy use accounted for first, with a mature mining, transportation and sales channels, and the price is relatively low; but it also has many defects, low efficiency, resource utilization imbalance, burning emit large amounts of carbon dioxide and other harmful gases and dust, the larger impact on the environment pollution and high environmental costs.
