Hongguang new type water fire tube boiler shell boiler is under the domestic well-known experts in boiler Li Zhiguang the professor personally guided, after years from combustion, heat transfer, water power and other innovative research and development, the development of suitable for a variety of quality of energy efficient products, its outstanding characteristic is technical content high, the high efficient heat transfer screw thread smoke tube, arched tube plate, backwater ejection and technology to solve the traditional pot shell type boiler tube plate crack. At the lower part of drum drum kits, low thermal efficiency, insufficient output, coal adaptability poor problem. The thread smoke pipe is arranged in the boiler barrel, which effectively reduces the size of the boiler, and ensures the safety and performance of the boiler.
