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 WNS series gas-fired hot water boilers are widely used in industries such as central heating, hotels, and hospitals. This series of gas-fired boilers adopts a wetback structure. The large-diameter corrugated furnace can not only effectively absorb the thermal expansion, but also increase the radiant heating area. With the advanced combustion equipment, this series of gas-fired boilerscan ensure the full combustion of the fuel, and the thermal efficiency can reach over 98%. And the WNS series boiler is a package boiler, which is fast to install and saves a lot of installation and capital investment costs. In terms of quality assurance, ZOZEN has established a strict quality management system. Each boiler needs to undergo strict quality inspection procedures to complete the final assembly.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
Industrial boilers provide a stable steam heat source for the drying, rolling, and vulcanization of tire processing. ZOZEN has reached cooperation with many rubber products manufacturers with high quality products. Sichuan Haida Rubber Group Co., Ltd. is an enterprise integrating R&D, operation and production of automobile tires, products include all-steel commercial radial tires, semi-steel passenger radial tires and oblique commercial tires.
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.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
