Case 1

The plant has three Combustion Engineering (CE) boilers, each rated at 750 MWe capacity.All units are functionally identical, each having a double or twin furnace, in which the center water wall heat transfer surface is shared by each furnace half. The total physical height of the furnaces is in excess of 120 feet from the top of the couton slopes to the elevation of the nose archEach furnace half is approximately 42 feet deep and 42 feet wide, hence the total furnace presents a total surface area of over 40,000 square feet for heat transfer.

Case 2

The plant has three Babcock and Wilcox (B&W) design boilers, each rated at 528 MWe capacity. All units are functionally identical, each having a single furnace. The total physical height of the furnaces is in excess of 100?from the top of the couton slopes to the elevation of the nose arch which typically marks the highest point in effective heat transfer, and the point where the convection pass (superheater, reheater etc) starts. The furnace is approximately 55 feet deep and 60 feet wide, hence the total furnace presents a total surface area of over 25,000 square feet for heat transfer. All burners are all mounted at the front and rear of the lower furnace. All boilers on site are fueled with 100% eestern coal. This type of coal is well known for its low sulphur qualities and low cost/BTU as well as the difficulty of removing the combustion residue. More...

Case 3

The installation is a 350 Mwe Unit. The total physical height of the furnaces is in excess of 116?from the top of the couton slopes to the elevation of the nose arch which typically marks the highest point in effective heat transfer, and the point where the convection pass (superheater, reheater etc) starts. The furnace is approximately 42 feet deep and 50 feet wide, hence the total furnace presents a total surface area of over 21,300 square feet for heat transfer. More...
