Modul-Pak - Multipass Firetube Boiler

The upper furnace is an extended watertube furnace which offers water cooling of the primary combustion chamber which results in cooling the flame temperature prior to entering the multipass firetube boiler.

The Modul-Pak boiler is offered in a wide variety of fuel firing combinations. Modul-Pak firing systems include gas/oil burners, McBurney air or water-cooled stationary grates, and continuous ash discharge stokers including air and water-cooled vibrating grates.
