Which ZOZEN Boiler models are best for a 20 t/h gas-fired steam boiler?
A: ZOZEN Boiler offers two proven options at 20 t/h: the WNS series and the SZS series gas-fired (oil-fired) steam boilers. WNS covers 1–20 t/h with 0.7–2 MPa, ideal when footprint is limited and maintenance simplicity is a priority. SZS covers 2–110 t/h with 1.25–5.3 MPa and outlet temperature 194–540 °C, suitable for higher pressures and continuous heavy-duty operation.
A: Both ZOZEN Boiler series support natural gas, coke oven gas, and biogas, with extensions to diesel, heavy oil, light oil, and crude oil. Advantages include high heat-transfer efficiency, optimized heating surface layout, low-NOx combustion, advanced automation and protection, plus optional economizer and air-preheater configurations for energy savings and emissions reduction.
A: Typical industries for a 20 t/h ZOZEN Boiler gas unit include heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, and hospitals. ZOZEN Boiler can tailor parameters to your required pressure and steam temperature.
A: Internationally, ZOZEN Boiler has delivered many 20 t/h-class gas projects across Southeast Asia, South Asia, the Middle East, Eastern Europe, and Africa. Strong export execution includes engineering customization, sea-freight logistics, on-site commissioning, operator training, and responsive after-sales, underscoring ZOZEN Boiler’s ongoing focus on overseas markets.
