ZOZEN’s YQ(Y)L series oil-fired/gas-fired vertical thermal oil heater adopts three-pass round coil structure whose end adopts conical coil which can effectively protect the furnace wall at the end of boiler. It is equipped with advanced combustion device with good energy saving and environmental protection performance. This kind of boiler has the characteristics of wide fuel adaptability, low pressure and high temperature, safety and efficiency, high thermal efficiency over 95%, and complete automatic control system which can realize unattended operation.

straw pellet boilers, ZOZEN SZS series boiler body is designed with D-type chamber combustion structure. The furnace is on right side and the convection heating surface is on left side. The membrane type structure is adopted for the circumference of the furnace body, the wall between the furnace and the convection zone, the front and rear walls of boilers body. The furnace pressure is designed to be greater than 6000Pa.

This is a membrane wall production line of ZOZEN Boiler. All the membrane walls inside the boiler are produced from here. The steel pipes pass through the polishing equipment and are reduced to the original metal color. Then they will enter the large-scale automatic welding station together with the flat steels that are cut beforehand. This welding station is as high as 4.6 meters with a covering area of 32 square meters. It is equipped with 16 welding guns which can complete the welding of 4 groups of membrane walls at the same time. The welding speed and precision are at the leading level in the industry. Finally, the welded membrane walls are made into various shapes by the pipe arrangement machine, straw pellet boilers.

According to the actual production demands of Lenzing (Nanjing) Fiber Co., Ltd., ZOZEN Boiler recommended the SZS series gas-fired superheated steam boilers. This series of steam boiler adopts the large-volume furnace to ensure the sufficient fuel combustion. Combined with an advanced low-NOx burner, it can easily achieve the low emission of NOx, which meets the environmental protection requirements of Lenzing Group. At the same time, in order to improve the boiler thermal efficiency, it not only uses the high-quality aluminum silicate fibers for the furnace body, but also uses high-temperature refractory mud for heat preservation. With the additional energy-saving equipment at the end of the flue gas duct, the boiler thermal efficiency is as high as 98% to save the operating costs.

For ZOZEN Boiler, the craftsmanship spirit is not only a concept, attitude and inheritance, but also a gene implanted in all links of enterprise research, development, manufacturing, marketing, service and culture. Many craftsmen who pursue for excellence have constantly improved their vocational skills to create one after another “Made by ZOZEN” with research, inheritance, concentration and perseverance.
