LSS Series Gas-fired Condensing Steam Boiler

Zhejiang XianChuang Energy Technology Co., Ltd. stands as a premier Class A certified boiler producer in China, holding public listing status along with ASME and CE accreditations while possessing over 30 patented technologies. Notably, its groundbreaking ultra-low NOx water-cooled premix combustion system has been effectively implemented in gas-powered steam generators and thermal fluid heaters, receiving recognition as Zhejiang Province's Pioneering (Innovative) Equipment.

The water-cooled premixed condensing steam boiler adopts self-developed water-cooled premixed combustion technology, featuring short flame, no furnace in the conventional boiler structure, single-pass flue gas, and a supporting flue gas condenser to fully recover and utilize the waste heat of flue gas. It not only has a large evaporation heating surface of fire-tube boilers but also the heat transfer surface of water-tube boilers. Through the unique structural design and the adoption of a closed-loop condensing water recovery system, high-temperature condensing water is directly sent back to the boiler for reuse. By comprehensively utilizing the sensible heat and latent heat in flue gas, and recovering and utilizing the heat of high-temperature condensing water from the source, it can not only save fuel costs and operation expenses, improve the comprehensive operation efficiency of the boiler, but also meet the requirements of ultra-low nitrogen emissions, ensuring safer, more energy-efficient, and more environmentally friendly operation.
