FIRETUBE

Completely ASME code compliant, a firetube boiler is made up of a cylindrical package containing a series of longitudinal tubes in which flue gas passes through in order to heat the water located in the boiler’s shell. “Fire” inside the tubes, water outside, allowing in turn for heat to be conducted directly through the system. Steam pressure wise, a firetube boiler can reach between 15 and 150 psig, depending on the applications.
