Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
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. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. 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.
In the pharmaceutical industry, steam is one of the important energy sources for pharmaceutical companies to produce heat for heating, concentration, drying and other processing steps in pharmaceutical production. ZOZEN 10 tph WNS series condensing gas-fired steam boiler has been successfully put into production after installation and commissioning. This condensing gas-fired steam boiler not only produces high-temperature saturated steam, but also can adjust the multi-speed according to the dema...
Serpentine tubes adopt automatic argon arc welding, which are performed X-ray real-time imagingto prevent unqualified welds from entering the bend process.
For decades, ZOZEN boilers has always guided the manufacturing quality of industrial boilers and established the technological standards of blanking digitization, automation of welding and assembly moulding. The full-automatic CNC tube bending production line greatly improves work efficiency and quality, providing a powerful guarantee for creating first-class products.
ZOZEN gasfired (oil-fired) organic heat carrier boiler adopts the three-pass circular coil tube structure, and the coil tube is produced by the fully automatic CNC coil tubes production line, which is once-forming and does not need to be re-formed.
The processing accuracy and welding quality of the tube sheet directly affect the operation safety of the boiler. ZOZEN imported the CNC high-speed plane driller to greatly improve the pipe hole processing precision and the surface finish of the hole, creating favorable conditions for the subsequent expansion process.
