Learn MoreEric Jeffs, in Generating Power At High Efficiency, 2008. The pilot plant was built indoors in the same format as a standard vertical boiler. The steam mass flow rate was 13.8 t/h at full load. The steam produced by the boiler was throttled down to 50 bar and condensed in a small air condenser formed by two cells of a typical lubrication-oil fin fan cooler.

Learn MoreMultiply the cubic volume of the room by the number of times you want the air to turn over or exchange in an hour. For example, if you expect the air to be exchanged twice per hour, multiply 2 times 640 to get 1,440. Divide your answer from step 3 by 60 to calculate CFM. In this example, you would divide 1,440 by 60 to get a CFM of 24.
