ZOZEN Boiler has cooperated with the Department of Thermal Engineering of Shanghai Jiaotong University to jointly develop the DZL series tri-drum biomass-fired boiler. This kind of steam boiler is a water tube boiler adopting the assembled structure with two parts. The boiler can be equipped with different grates to ensure the sufficient combustion of biomass fuels.
The WNS series light diesel boiler built by ZOZEN Boiler adopt a packaged structure, which is composed of the boiler body, burner, economizer, condenser, water and steam system and control system. It has the advantages of less occupied area, convenient installation and maintenance. This time, the boiler solution customized by ZOZEN for Inversiones Goa 7 C.A. not only has sufficient output, but also has the advantages of convenient operation, environmental protection and high efficiency while meeting customers needs, and all technical indicators have reached the advanced level at home and abroad. According to the video data sent back from the customer site, ZOZEN WNS oil-fired boiler is operating very well.
Among many boiler types, biomass-fired chain grate boiler has the advantages of wide fuel adaptability, low original emission concentration, low operating costs and easy operation. Based on the eco-friendly development thinking, ZOZEN Boiler has long been designing and manufacturing the chain grate boilers. At present, the DZL series industrial boiler adopts the advanced arch design, independently developed membrane water-cooled wall structure, special slag removal technology and reasonable sealing grate structure, which shows an obvious performance advantage.
WNS series gas-fired or oil-fired hot water boiler is smoke-fire tube chamber combustion boiler and adopts two-pass or three-pass structure. It also adopts large-diameter waveform stove furnace with good thermal expansion and safety performance. There are condenser and economizer added at the end of flue gas duct which can improve the thermal efficiency to more than 95% and save boiler's operation costs.
ZOZEN customized the gas-fired hot water boiler system, and recommended several sets of SZS series natural gas fired hot water boilers, which had the characteristics of sufficient output, high thermal efficiency and stable operation. This series of boilers is designed with longitudinal double drums and "D" type chamber structure.
All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, soft water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. Skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency. In addition, the water circulation structure of DHL series coal-fired boilers is identified the first domestic product in China due to its reliability and advancement. It is widely used because its comprehensive performance has exceeded similar products on the market.
