ZOZEN YLW series coal-fired and biomass-fired chain grate thermal oil heater is favored by Indonesian customers because it has the features of high temperature and low pressure, precise temperature control and high quality. Heater proper and chain grate are transferred separately. The pictures show the heater proper is on the delivery. YLW series thermal oil heater adopts the square coil structure to realize high safety and sufficient heating surface. The tubes are firstly bent by CNC 3D tube bending machine, then welded to link together without forced assembly. YLW series thermal oil heater adopts the structure of a large furnace to achieve sufficient combustion and realize the thermal efficiency of over 85%. It is available for the bituminous coal, anthracite, all kinds of biomass particles, sawdust, etc.
In the long-term production and operation, ZOZEN Boiler always pays attention to the renewal of process equipment and continuously improve the quality and performance of various series of boiler products. The large-scale fiber laser cutting machine being developed by ZOZEN Boiler is similar to the existing plasma cutting machine, and has the characteristics of high accuracy, good repeatability and numerical control programming. In addition, it also has the advantages of faster processing speed and higher accuracy. The accuracy of cutting steel plates can be controlled within 1 mm, which effectively improves the welding and assembly quality of boilers.
The tube end forming machine is a kind of processing and forming equipment used for tube expanding, necking and shrinking under normal conditions. It is widely used for the processing and forming of boiler stainless steel tubes. The boiler components with high processing precision are the quality assurance of boiler welding and assembly. ZOZEN introduced the advanced tube end processing equipment which adopted the PLC control system and hydraulic drive, which could complete the necking of stainless steel tube ends with high efficiency and safety. It was also wear-free and had good product repeatability.
ZOZEN WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace and threaded smoke tube to increase the heating surface, reduce the thermal stress and improve the boiler's safety performance; meanwhile, in order to reduce the heat loss caused by gas exhaust and operating costs, ZOZEN also adds energy-saving devices at the end of the flue gas duct to improve the thermal efficiency to over 98%. In addition, the two sets of boilers also meet the ASME standards, which proves that ZOZEN product quality is up to international standards.
The ZOZEN 4 tph WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace, which increases the heat transfer surface, reduces the thermal stress and improves the boiler safety. Meanwhile, in order to reduce the heat loss due to exhaust gas and operating costs, ZOZEN also installs the energy-saving equipment at the end of the flue gas duct to ensure boiler's thermal efficiency reaches 98% and above. What's more, WNS series boilers also have the characteristics of fully automatic intelligent control and easy operation to ensure boiler's long-term, safe and stable operation, so they are well received by users at home and abroad.
ZOZEN Boiler has accepted a lot of orders in 2020. In order to meet the order requirements of customers, ZOZEN workers in the workshop are working overtime to catch up with the progress. There is a busy scene in the workshop of ZOZEN Boiler that workers are working hard on their own positions to ensure that the output can keep up with the sales volume. In the workshop, an orderly production scene can be seen with steel spattering and machine tools roaring.
ZOZEN WNS series gas-fired hot water boiler adopts packaged structure, which is convenient and quick for installation to save a lot of basic construction costs for the enterprise. Its internal structure adopts large-diameter waveform strove furnace which can effectively absorb heat expansion to add the radiation heating surface and ensue the low emission of NOx with the advanced low-nitrogen burner to improve the fuel utilization. What's more, its thread smoke tubes have scientific pitch and depth to further strengthen the convective heat transfer and make boiler's thermal efficiency reach 95% and above.
ZOZEN Boiler has guided the industrial boiler manufacturing quality for decades. It also has established the technology standards of blanking digitization, automation of welding and assembly moulding to realize the specialized and scale production of boiler's main parts. For further improving the boiler production efficiency and product quality, ZOZEN's Yixing factory introduced a series of new equipment including laser cutting machine, grooving machine, blending machine and sand blasting machine.
