Dowell Industrial Services has used the foam method of chemically removing deposits from utility surface condensers for approximately twenty years. Surface condensers are used to condense steam and to produce a vacuum at the turbine exhaust. Condenser tubes become fouled with scale during operation resulting in the decrease of heat transfer rate of the surface condenser. This loss in efficiency will decrease maximum power output of the generating unit and require the use of more fuel. Greater attention to improved condenser efficiency has been noted within the utility industry with increasing fuel costs and short fuel supplies.
