ZOZEN SZS series gas-fired (oil-fired) boilers adopt full-membrane wall structure for good sealing performance and have the charactics of sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
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.
