FPS VERTICAL FIRETUBE
This vertical firetube boiler has a capacity range of 330 PPH to 3,440 PPH with up to 83% efficiency. The design allows for improved efficiency resulting from a bottom fire power burner. Positive advantages include large water volume and steam chest that lowers cycling, and an internal feedwater pre-heater which improves unit efficiency and lowers the risk of thermal shock. The 4 piece design includes a combustion chamber, pressure vessel, combustion gas collector with flue and a cabinet. Single pass heat transfer area sized at 4 sq. ft per BHP provides max heat transfer.
