Boiler Construction: Watertube Boilers

In the boiler shown above, the furnace is fully water-cooled and of monowall construction, it is produced from finned tubes welded together to form a gastight casing. With monowall construction no refractory material is necessary in the furnace. The furnace side, floor and roof tubes are welded into the steam and water drums.
