VFS series of vertical fire tube oil/gas fired steam boiler adopts corrugated furnace and thread pipes structure, which not only improves the strength but also meets the needs about the heat expansion of various parts. The boiler has a large water volume and steam space, and has a strong ability to adapt to heat load. It is slightly positive pressure combustion, the heat load is low during combustion, and the emissions of the harmful substances such as NOX is few. The high temperature flue gas comes into the first tube bundles from the furnace. After 180 degrees reentry, it enters the second tube bundles, and is discharged into the atmosphere after the heat is absorbed. There is an openable ash cleaning port at the bottom of the boiler, which is convenient for cleaning ash and prolonging the service life of boiler. The boilers equip with imported burner and fully controlled, so that it can achieve the best combustion effect.
