Advanced equipment is the strong support for industrial boiler manufacturers. As an internationally renowned boiler manufacturer, the advanced automated production line in the modern workshop of ZOZEN Boiler not only shortens the manufacturing cycle of the boiler, but also improves the quality of the boiler and extends the service life of the boiler. At the same time, orderly production management and rigorous quality inspection are also an important part of completing the lean manufacturing of boilers. Through the advanced sales mode of live webcast, the strong strength of ZOZEN Boiler is passed on to overseas users through internet. And overseas users are feeling like on the scene!
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.
ZOZEN WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
ZOZEN SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.
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.
This is gas-fired/oil-fired thermal oil heater from ZOZEN Boiler which is widely used in petroleum, chemical fiber, pharmaceutical, printing and dyeing and other industries that require high-temperature heating. The thermal oil heater adopts heat medium oil to transfer the heat energy. Applying high temperature of heat medium oil, the boiler can realize low pressure and high temperature heating with a working temperature of 320℃. Meanwhile, our thermal oil heater is equipped with the complete device for operation control and safety supervision which can precisely control the working temperature with convenient operation and high safety performance.
ZOZEN WNS series gas/oil-fired steam boilers have outstanding eco-friendly performance. The flue gas emission of WNS series gas/oil-fired steam boilers can meet the environmental protection standards. Facing the strict low NOx emission requirements across the country, ZOZEN Boiler realizes the low emission of NOx (less than 30mg/Nm3) via the advanced low-nitrogen burner and combustion technology. ZOZEN WNS 20 tph steam boilers are applied in the food, chemical and nonferrous metal industries.
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.
