The 3 sets of 29 MW gas-fired hot water boilers serving for Jin-an Thermal Power in Tianjin were installed in 2015. The boiler is a common type for central heating which adopts the full membrane wall structure and a D-type layout. It has the characteristics of micro-positive pressure combustion, no air leakage, low heat loss caused by exhaust gas and high thermal efficiency. During the boiler manufacturing process, ZOZEN Boiler emphasizes that the welding of each baffle must be tight, and the height of welding leg should meet the requirements specified on the design drawing to ensure the leakproofness of the boiler. In addition, ZOZEN Boiler also sets strict welding standards for detailed parts including the door opening and kiln eye to prevent the high-temperature flue gas from leaking.
This is ZOZEN thermal oil heater adopts the multi-circuit coil design with sufficient heating surface and good heat transfer effect which effectively protect the burner and furnace wall. The boiler adopts high-quality refractory and thermal insulation materials which can well reduce the heat loss based on the different refractory and thermal insulation structure for areas with different temperatures. In addition, based on the actual conditions, we also add the waste heat boiler, economizer, air pre-heater and other energy-saving equipment to make exhaust gas temperature to less than 90℃ and the thermal efficiency to reach over 95% and to help the enterprise reduce consumption and the costs.
The new generation of SZL series boiler is cooperated with Shanghai Jiaotong University. It increases the furnace height, increases rotating speed, adds ash blowing device and designs ash removal system at the bottom of the grate. These well solve problems like scaling, abrasion, front arch, etc. It can also reduce the maintenance and operating costs and extend the service life of the biomass-fired boilers.
ZOZEN energy-efficient WNS series gas/oil-fired steam boilers have two-pass and three-pass structures. This series of boilers adopt the large-diameter corrugated furnace and threaded smoke tubes with high heat transfer efficiency. With the economizer at the end of the flue gas duct, they can enlarge the boiler's heating surface, lower the exhaust gas temperature to 60℃ and improve the boiler's thermal efficiency to over 98%. ZOZEN WNS 8 tph steam boilers are applied in the food, chemical and heating industries.
ZOZEN 15 tph SZS series steam boiler is widely applied in the printing and dyeing, nonferrous metals, chemical and other industries. The SZS series boiler is designed with longitudinal double drums and "D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
YQW series thermal oil heater adopts three-pass round coil structure with larger inner coil design to ensure boiler's safe operation under high temperature. It is also equipped with advanced burner and control system. They realize the automatic and stable operation of thermal oil heater. There is waste heat recovery device as well to improve the thermal efficiency to 95% and above.
WNS series gas-fired or oil-fired boiler as the popular type of ZOZEN boiler is highly efficient and eco-friendly. In the finished warehouse, WNS series gas-fired or oil-fired boilers and all kinds of auxiliary machine and parts waiting for shipment are arranged orderly. The standard products can be delivered from stock. Intelligent production mode makes the delivery speed of ZOZEN Boiler faster than that of other boiler providers.
Founded in 2002, Wujiang XinYi Textile Co., Ltd. is a joint-stock private enterprise integrating production and trade of various kinds of high-end fabrics. With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control.
