Design: The horizontal internal combustion three-pass full-wet back design, with 100% corrugated furnace tube, boasts excellent thermal expansion properties. The water包围fire overall design, with ample heating surface area and rational structural arrangement, ensures high-efficiency boiler operation. High Efficiency and Energy Saving: Steam and hot water boiler series have thermal efficiencies between 97% and 99%. The large combustion chamber, combined with rational structural arrangement, transfers more heat to the water, greatly enhancing the heat exchange capacity between fuel and steam, and fuel and hot water. Environmental Compliance: The spacious combustion chamber maximizes radiant heat exchange, and with a high-quality, reliable imported burner, ensures complete combustion of the fuel, significantly reducing harmful emissions in flue gas. Our fuel (gas) steam and hot water boilers meet national environmental standards and are ideal eco-friendly products. Excellent Configuration: Equipped with world-renowned burners, advanced control systems (main components are imported), valves, and pumps are all of national quality products. The superior boiler accessory configuration provides a strong guarantee for the safe and stable operation of the boiler. Automatic Operation: Users simply need to press the start button, and the boiler will operate according to the set program, with load regulation and water supply all being fully automatic, requiring no constant supervision. Easy Maintenance: The boiler features movable smoke box doors at the front and back, with a view fire hole and inspection holes at the rear, allowing access to the furnace for inspection and cleaning. A manhole is also provided on the boiler body, with the structural design taking into account ease of future maintenance and repair.
