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.

For many manufacturers with mature production experience in China, expanding capacity overseas or building a new factory abroad often starts with one key question: can the local infrastructure and energy supply support long-term operation? This is especially important in Africa. In many countries, raw materials such as timber are readily available, while conventional fuels like natural gas and diesel are often more expensive and less stable in supply. For plywood plants, this creates a practica...24 Mar 2026 -
From late 2025 to early 2026, forward-looking reports from the World Economic Forum (WEF) and other organizations indicated that despite significant growth in global renewable energy capacity in 2024, global carbon dioxide emissions still reached historical highs. Facing severe climate safety challenges, multiple countries globally have introduced stricter environmental policies to promote a green and low-carbon economic transition. In this macro context, energy conservation and emission reducti...17 Mar 2026 -
