What are the technical advantages of ZOZEN's 20 ton gas boiler for large-scale industrial applications?
For industries requiring substantial steam output, a 20 ton gas boiler is a critical asset. ZOZEN recommends its SZS series and WNS series for this capacity range. The SZS series 20 ton gas boiler is a double-drum longitudinal type, featuring a "D" type layout. This design is robust and safe, offering a large furnace volume that ensures complete combustion.
A key advantage of ZOZEN’s 20 ton gas boiler is its environmental performance. Equipped with advanced low-nitrogen burners and Flue Gas Recirculation (FGR) technology, these boilers can achieve NOx emissions as low as 30mg/Nm³, complying with strict environmental regulations globally. The thermal efficiency exceeds 100% due to the inclusion of condensers and economizers at the tail of the flue, which recover latent heat from the exhaust gas.
From a manufacturing perspective, ZOZEN utilizes automated production lines for these boilers, including coil production and membrane wall manufacturing. This ensures high precision and durability. The control system is fully automated, allowing for unattended operation, which significantly reduces labor costs for the user. With over 15,580 successful cases, ZOZEN’s gas boilers are a trusted choice for textile, food processing, and chemical industries worldwide.
