Modul-Pak®
The Modul-Pak® boiler is a hybrid design that combines the benefits of a watertube furnace and a multipass firetube boiler. The results are a value engineered modular package boiler that offers unique advantages for solid fuel firing.
2-Drum Bottom Supported Boiler
The McBurney 2-drum bottom-supported boiler is a 2-gas pass balanced draft, natural circulation boiler design. The boiler is designed for medium to large industrial boiler applications.
2-Drum Top Supported Boiler
The 2-drum top-supported single gas pass balanced draft, natural circulation boiler is designed with a water-cooled membrane wall furnace. The boiler is designed for large industrial boiler applications.
Modul-Pak®
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.

2-DRUM BOTTOM SUPPORTED BOILER
The 2-drum bottom-supported boiler is offered in a wide variety of fuel firing combinations including gas/oil burners, solid fuel suspension burners (for sander-dust), and continuous ash discharge stokers including traveling grate, air and water-cooled vibrating grates.
The furnace and the boiler are designed for the specific requirements of the fuels to be fired and boiler operating conditions. The furnaces are conservatively sized to improve fuel combustion and burnout, reduce particulate emissions carryover, and provide low furnace volume heat release rates.
By having two gas passes through the boiler bank, the boiler exit gas temperature is lower than a top-supported single gas pass boiler design. This results in a smaller tubular air heater and/or economizer.
For superheated steam applications, a radiant and/or convective pendant type superheater can be provided.

2-DRUM TOP SUPPORTED BOILER
The 2-drum top-supported boiler is offered in a wide variety of fuel firing combinations including gas/oil burners, solid fuel suspension burners (for rice hulls and sanderdust), and continuous ash discharge stokers including traveling grate, air and water-cooled vibrating grates.
The furnace and boiler dimensions including height, width and depth and drum centers are selected and optimized for the specific requirements of the fuels to be fired and the boiler operating conditions. The furnaces are conservatively sized to improve fuel combustion and burnout, reduce particulate emissions carryover, and provide low furnace volume heat release rates.
Radiant/convective superheaters are designed to provide the required team outlet temperature over the required load range. The superheaters are a pendant design located prior to the convection bank.
