ZOZEN Boiler provided an energy-saving and environment-friendly WNS gas-fired steam boiler for a food enterprise in Suzhou. The gas-fired steam boiler adopts two-pass design, and the use of large-diameter corrugated furnace and threaded smoke tube make the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach more than 98%.
Boiler economizer is an important energy saving device in boiler system. Its principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in the smoke. Economizer can be divided into cast iron economizer and steel tube economizer according to different manufacturing materials. This gallery displays the cast iron economizer produced by ZOZEN Boiler. The cast iron economizer is mostly used in boilers with pressure ≤2.5 MPa. If the pressure exceeds 2.5 MPa, the steel tube economizer should be adopted.
Recently, a set of ZOZEN SZS series gas-fired boiler was shipped to Henan Province. The customer is a leading enterprise in the domestic metal products industry, mainly producing new materials such as steel cord and galvanized steel strand for radial tires. ZOZEN SZS series gas-fired boiler adopts the large furnace structure with sufficient heating area. It has the advantages of high thermal efficiency, sufficient steam output and energy conservation.
A boiler is an essential piece for the new material industry, providing thermal energy for the production process of lithium hydroxide, lithium carbonate, etc. Considering the complexity of the production process of the new material industry, ZOZEN Boiler highly recommends the gas-fired and oil-fired steam boiler and the thermal oil heater. ZOZEN gas-fired boiler is favored by new material customers because of its reasonable structure, high steam quality and sufficient output. The end of the boiler is equipped with various energy-saving devices designed by ZOZEN engineers and it can effectively improve the overall thermal efficiency of the boiler.
The new customized type of ZOZEN SZS series oil/gas-fired boiler is now available on the website. The new appearance of SZS series acquires the patent No. CN202030030831.X with the good performance of anticorrosion. Also, the well-structured 'D' type chamber with large volume design ensures the sufficient combustion and good airtightness. The imported low-NOx burner can easily control the generation of the NOx.
ZOZEN Boiler has designed a technical scheme for the project, including 3 sets of SZS series gas-fired superheated steam boilers and 1 set of WNS series gas-fired superheated steam boiler, of which two medium-temperature and medium-pressure SZS series gas-fired superheated steam boilers are used to cooperate with steam turbine for power generation.
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 longitudinal seam welding adopts advanced submerged arc automatic welding technology to ensure welding quality. After the pre-welding treatment, ZOZEN uses automatic argon arc welding technology to complete the butt welding of steel pipes, and performs X-ray real-time imaging of the welds to prevent unqualified welds from entering the next production process. The advanced automatic welding machine completes the automatic welding of the longitudinal seams under the tracking of the photoelectric system, which not only improves the efficiency but also effectively guarantees the welding quality.
