Low-NOx burners from Stiefel (Guangdong) Energy Environmental Protection Engineering Co., Ltd. aim to slash nitrogen-oxide emissions and still burn fuel pretty well. That balance helps plant operators stay on the right side of tough pollution rules. The engineering team folded in tricks like staged combustion and flue-gas recirculation; both methods cool the flame just enough to keep NOx from sky-high levels. A hardened alloy skeleton stands up to the daily grind of heat and pressure, so operators can count on years of trouble-free service. These burners slip into boilers, furnaces, or any heavy-duty heater you can name, making them a natural fit for factories that want green credibility without sacrificing steam or heat output.
