Firetube Boiler System

Modul-Pak®: The Modul-Pak® boiler is a hybrid design that combines the benefits of a watertube furnace and a 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.
