Industrial boilers have been widely used in the chemical industry all the time. They play an indispensable role in the pretreatment, hydrogenation, decomposition, and distillation of oleochemicals. Hangzhou Oleochemicals Co., Ltd. was founded in 1973 (the predecessor was Hangzhou Grease Chemical Factory) is a state-owned enterprise which was invested and built by the former Ministry of Light Industry of China. The enterprise was restructured in 2000 and it is now a wholly-owned subsidiary of Zhejiang Zanyu Technology Group Co., Ltd. that has formed a style of simultaneous development of multiple products series. It supplies significant raw materials for manufacturing industries in food, chemicals, plastic, rubber, cosmetics, flavor and fragrance fields and deeply win trusts from many customers at home and abroad.
With outstanding advantages of the comprehensive performance of the SHX circulating fluidized bed steam boiler, ZOZEN became the coal-fired boiler supplier of Sanming Fengrun Chemical Co., Ltd. Founded in May 2005, Sanming Fengrun Chemical Co., Ltd. is a main pharmaceutical and feed carrier silica manufacturer engaged in the production and sales of silica (white carbon black). Its products are widely used in shoe soles, silicone rubber, green tires, pharmaceutical carriers, feed, food and other industries. The ZOZEN SHX circulating fluidized bed steam boiler can meet all the requirements of Fengrun Chemical on the production line in terms of efficiency and environmental protection and improve its economic benefits.
ZOZEN SHL series field assembled hot water boiler is a natural circulation coal-fired water tube boiler with double drums, which is widely used in central heating industry. With advantages in performance, the ZOZEN SHL series coal-fired boiler became an important facility of the boiler room of Xinjiang Huadian Hami Thermoelectric Power Co., Ltd. The horizontal two drums form a shaft-type furnace with the membrane wall and form the boiler proper with the convection tube bundle header, which has the features of fast temperature rising, high thermal efficiency and less occupied area. Meanwhile, this series of boiler adopts the flake type chain grate to improve the operation reliability, which has no coal leakage. In addition, the boiler is equipped with an advanced air distribution system, which can reasonably adjust the air volume according to the coal property and combustion conditions. Moreover, the SHL series coal-fired boiler has advantages of high degree of automation, stable operat
ZOZEN ZZ series mid-temperature and mid-pressure boiler has advantages of wide fuel adaptability and high combustion efficiency. Meanwhile, ZOZEN technicians scientifically designed the boiler system according to the actual needs of the production lines of Rashid Paper Mills Ltd. This ZZ series coal-fired boiler adopts a wide-coal-type furnace arch design to increase the furnace temperature. At the same time, isobaric storehouse draught and micro-zone air distribution are designed to reduce the carbon content of the slag, which improves the overall combustion efficiency. In addition, this series of boiler is a field-assembled boiler which has high requirements for the technicians and installation staff. In order to ensure the smooth completion of the project, ZOZEN technicians provided effective on-site guidance for Rashid Paper Mills Ltd. After the boiler is entered the commissioning stage, ZOZEN will also provide users with professional training from boiler working principles and ope
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
Generally, the consumption of the steam boiler fuel in the textile industry is relatively large. Therefore, the steam boiler as an important piece of thermal source equipment will effectively impact the quality of textiles and the production efficiency of textile companies. Xindadong Textiles (Vietnam) Co., Ltd. is committed to the research and development of new type yarns and high-quality denim fabrics, supplying excellent products to the world famous brand, such as VF, Esquel, Youngor, LEE, WRANGLER, C & A, etc. Xindadong Textiles has begun to implement an international expansion strategy since 2013 and established a production base in Vietnam.
ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
SZL series steam boiler is a longitudinal double-drum chain grate water tube boiler designed by ZOZEN on the basis of advanced international technology and its own experience. 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. the combustion air system (base) adopts independent compartment and scientific sealing structure; reasonable air conditioning device improves combustion efficiency. The water membrane wall, the front and rear arches and the hearth constitute the boiler furnace, A bank of return convection tube bundles are arranged at the rear of the boiler body to sufficiently absorb the heat released by the combustion. The SZL series chain grate steam boiler system customized by ZOZEN has excellent performance and the thermal efficiency is more than 5% higher than the similar boiler system on the market.
