FBC Steam Boilers

Product Description

Ultra Boilers ( Ultra Boiler) requires minimum site work as they are factory assembled units and is mounted on a skid base frame. Their working is same as our Combitherm model in a way that they too are the combination of water tube design and smoke tube design. Combitherm Ultra model is also a 3 pass design with 1 pass of flue gases in external furnace or membrane which is surrounded by water tubes and 2 passes of flue gases in shell tubes just like the Ultra Model.

The only difference is that it is a compact design and requires less space as compared to the Ultra design. In this water, tube membrane is many compacts thus allowing minimum or no radiation losses to the surroundings. The shell in the case of the Ultra model is placed just above the membrane thereby reducing the time for water to reach the membrane through downcomers thereby allowing easy and faster water circulation. This mainly prevents the overheating of radiation tubes and eventually increases the operating life of your boiler. In this downcomers are provided on the sides of the shell membrane assembly and riser headers and pipes are provided in between the shell and the membrane.
