This CWNS‑series horizontal atmospheric hot water boiler adopts a mature direct‑heating structure, with its main body composed of a boiler shell, furnace tank, reversal chamber, front & rear smoke boxes and fire tubes. The large‑diameter corrugated furnace tank enhances heat transfer efficiency, while the wet‑back flue gas structure effectively avoids corrosion risks caused by high‑temperature flue gas scouring, perfectly adapting to the strict working conditions of 24‑hour continuous stable heating required by coating production lines. Optional touch‑screen and PLC intelligent electronic control systems precisely regulate heating temperature, meeting high standards of water temperature and thermal stability for automobile spraying, drying and other processes.
Featuring a modular design, the boiler is easy to install with a short construction period, quickly adapting to the construction rhythm of industrial plants. Operating safely under normal atmospheric pressure, it requires no complicated pressure‑bearing inspections, with simple maintenance and high safety factors. Low‑temperature backwater inhibits low‑temperature flue gas corrosion and extends service life effectively. Equipped with an intelligent control system, it realizes fully automatic constant‑temperature regulation and real‑time monitoring, providing stable, energy‑saving and eco‑friendly thermal support for coating production lines and reducing production energy consumption and operating costs for enterprises.
Weifu Boiler specializes in thermal energy solutions for multiple fields including industrial heating, automobile manufacturing, coating chemical industry and municipal livelihood projects, with rich experience in implementing industrial production line heating projects. The FAW Huanghua coating line project serves as a vital benchmark case of Weifu’s empowerment in the automobile manufacturing sector, fully demonstrating our technical strengths in industrial‑grade continuous heating, intelligent temperature control, energy saving and low‑nitrogen emission.
In the future, Weifu Boiler will continue to focus on heating demands of the industrial manufacturing industry. With safe, efficient, low‑carbon and intelligent boiler equipment, we will empower more industrial production projects such as automobiles, chemicals and machinery, offering reliable thermal energy support for high‑quality development of the manufacturing industry.
