In response to national environmental protection policies and initiatives for energy conservation and emission reduction, many printing and dyeing companies have technically reformed coal-fired boilers on their original production line. Among them, Wujiang Lianhua Dyeing and Finishing Co., Ltd. was established in 2002, and has now developed into a large-scale production enterprise integrating weaving, dyeing and finishing, printing and import and export trade.
ZOZEN DHL series coal-fired watertube hot water boilers are ideal equipment for central heating. This series of boilers are forced-circulation, single-drum horizontal chain grate hot water boilers. Membrane water walls are arranged around and in the middle of the furnace to absorb the radiant heat of high-temperature flue gas in the furnace. And the large furnace extends the residence time of the flue gas in the furnace, making the fly ash and combustible gas be fully burned, which not only improves the thermal efficiency, but also greatly reduces the amount of fly ash and the original emission concentration of the boiler. The boiler arch adopts the scientific and technological achievements of the Xi'an Jiaotong University's to ensure the combustion effect of inferior coal and expand the coal adaptability. Boiler grate adopts bar grate to improve the operation safety. Through stepless speed regulation, users can adjust the load arbitrarily without affecting the thermal stability of com
ZOZEN has played an active role in promoting the process of "coal to gas". In particular, the WNS series of gas-fired steam boilers have gained a good reputation in the industry due to their safe and efficient performance. This gas-fired boiler features compact design and is equipped with boiler control, alarm and interlocking devices of water level and steam pressure to ensure safe and reliable boiler operation. And the large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes increase the heating surface. With the energy-saving device at the tail of the flue, the exhaust gas temperature is reduced below 60℃, and the thermal efficiency is as high as 98%, helping clients achieve their goal of energy saving and emission reduction.
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.
The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital. Hot water and steam are essential energy sources for large comprehensive hospitals, providing adequate steam heat energy support for hospital heating and daily disinfection. Under the background of current energy-saving emission reduction and refined management, the Second Hospital of Jilin University actively responded to the national “coal to gas” policy and decided to replace the old boiler equipment with low efficiency and high emission.
The process of dyeing, drying, pressing, sizing, printing and dyeing, shaping and other processes in the textile industry are supported by the steam. Therefore, steam boilers are important equipment to ensure the normal production process of textiles. SOORTY is one of the largest vertically integrated denim manufacturers from Pakistan. Production capacity of 60 tons yarn per day, 5.5 million meters fabric per month and 2.8 million garments per month makes them leader of the league.
The processing of agricultural products requires a lot of procedures, and steam. Is demanded for the procedures of disinfection and aseptic packaging. Therefore, steam boilers are important equipment. Agra Feed S.A.S. was established in 2011. It is an enterprise in Colombia, operating in the Farm Product Raw Material Merchant Wholesalers industry. In recent years, due to the continuous expansion of the company's production capacity, Agra Feed S.A.S. urgently needed to purchase one set of energy-efficient steam boiler.
The winter in Liaoning Province is long and cold. As an important heating device, the stability of the boiler operation will directly affect the life of the people. In order to successfully complete the central heating task in winter, Huludao Longgang District Heating Co., Ltd. , held an open bidding in the whole country for the coal-fired hot water boiler. The coal-fired hot water boiler produced by ZOZEN is famous in the northern boiler market for its excellent performance, reliable operation and friendly environment protection. Huludao Longgang District Heating Co., Ltd preferred ZOZEN boilers and ordered 2 sets of DHW series coal-fired boilers.
