chinese station california 35t boiler
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam chinese station california 35t boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
What are the reasons affecting the efficiency condensing chinese station california 35t boiler
Condensation boiler condensing apparatus refers to an increase in the vicinity of boiler flue gas, the fuel again absorb heat in combustion temperature flue gas discharged from the flue gas sensible heat and latent heat part together, make full use of. The greatest benefit of the condenser is added to the boiler thermal efficiency of the boiler can be increased by 10%, saving fuel input costs.
4 tph WNS gas-fired fire tube chinese station california 35t boiler project for dairy industryAs the key device in the production line of dairy industry, a steam boiler provides a plenty of steam for many production processes including distilling, disinfecting and sterilizing; a high-performance steam boiler has a direct impact on the product quality. Guangxi Shibu Dairy Industry Co., Ltd., established in 1995, has been developed into a large modern dairy enterprise mainly producing dairy products. To meet the increasing market demands, Shibu Dairy has introduced 28 domestic and international production lines as well as building a well-organized milk source base and a cold chain transportation system of fresh milk. A steam boiler plays a significant part in the production line; therefore, Shibu Dairy treated the purchase of the steam boiler as the top priority, they held a large-scale public bidding all over the country to seek the high efficient and environmentally friendly gas-fired boiler. ZOZEN successfully won the bid with its premium products and systematic solutions and provided them with 2 sets of WNS gas-fired steam boilers (WNS4-1.25-Q). This series of boiler adopts a large-diameter corrugated furnace to increase furnace heat transfer area, ensuring the stable running of the boilers. In addition, the boiler is equipped with a low NOx burner to reduce the NOx emission; furthermore, ZOZEN also installed economizer and condenser on the tail of the gas-fired boiler, which will effectively improve the thermal efficiency up to 98%.
Explosion reason a company szs Boiler tube 1, the general case where the defect causes, the heating surface tubes squib occur, mainly due to the metal wall than the level of stress due to material yield limit at the temperature of use. In operation water tube chinese station california 35t boiler tube szs mainly in the following aspects: (1) the quality of the boiler itself: as waterwall tube wall thickness and material problems; circulation unreasonable distribution, water wall tube heat exchanger disorders and the like; (2 ) inner heating surface fouling: difference in feed water quality, high hardness components, the inner tube fouling seriously hinder heat exchange tube of the heat exchanger; (3) the burner is provided: a bias furnace combustion flame, the direct flame flushing water wall, causing part of the water-cooled the wall temperature is too high, resulting in the squib; (4) operating failure: dry water, causing an imbalance in the furnace water cycle, water or a water partial power down, resulting in dry squib. 2, direct cause (1) the direct flame flushing water wall surface, resulting in heat concentration, so that a high thermal load side Water Wall, and subject to greater stresses; (2) so that the wall thinning flue gas erosion wear, high temperature corrosion, oxidation Paper warped, deterioration of the final material, a decrease in strength; and (3) quality is not up, the heat pipe scale, mass magnetization component adsorbed on the wall, the metal wall impact effective heating. From the above analysis we can see, because the multi-factor over temperature, corrosion, scale, and alternating stress contributed Wall squib leakage. After a company szs water boiler tube corrective measures (1) of the crater burner to transform the 45-degree burner throat flared original divergence angle transformation of the straight-shaped throat. Reduce diffuse flame burning in diameter, to reduce the intensity of direct flame scour the left wall of water wall; (2) to strengthen water quality management, improve the overall quality of water treatment workers and operational capacity, increase water quality laboratory tests; (3) water treatment update equipment, softened water to meet the water supply needs of the boiler, and to achieve "industrial boiler water quality" standards GB / T1576, improve heat transfer and water vapor circulating water wall, to protect the safe operation of the boiler. (4) water treatment operations personnel training, improve operations and laboratory analysis of water level.
