Key Features: |
Highly Integrated economizer&condenser&air preheater, minimize boiler footprint. Both combustion and water feeding VFD control, save electricity up to 30%. Split-type VFD fan, accurate air volume and pressure control, fuel burnout rate 99%, save fuel cost. Unique air cooled smoke box design without refractory cement, Lifelong maintenance-free, saving maintenance costs Bottom water return design and backwater circulation technology prevent tube sheet cracking |
Ultra-low NOX condensing pressurized hot water boiler is a two-pass fire tube boiler with wetback, high efficiency, and low stress. It is integrated with high-efficiency air preheater and economizer& condenser. An arc-shaped double-open furnace door for easy maintenance, air-cooled smoke box , and uses a large furnace for full-mixed combustion and high-efficiency threaded smoke tube heat transfer; it is the first to use low-nitrogen coupling and has a unique low-nitrogen combustion technology in the furnace to comprehensively suppress the production of nitrogen oxides (NOx); Equipped with ABB inverters, split low-nitrogen burners, 7/10-inch LCD touch screens and high-performance PLC programmable controllers, which fully meet the boiler's ultra-low NOx emission standards.
