Fouling Effects of Turbine Exhaust Gases on Heat Exchanger Tubes for Heat Recovery Systems.

Abstract

The use of heat recovery with shipboard gas turbine engine exhausts has generated a need to examine operational problem areas of waste heat boilers (WHB's). To ensure dependable boiler operation, it is necessary to minimize gas-side fouling of boiler tubes if the fouling cannot be eliminated. This fouling of a waste heat boiler will produce increased boiler core gas pressure drop which increases back pressure on the gas turbine propulsion engine, resulting in loss of power output and higher fuel consumption. Gas-side fouling also produces films which act as resistances to heat transfer and as media for corrosion of boiler tubes. This report summarizes work done at this Center on the subject of gas-side fouling of boiler tubes. Some of the goals of this effort are to: 1. Establish fouling film build-up rates under simulated WHB economizer tube conditions. 2. Study fouling effects on heat transfer. 3. Characterize fouling film chemistry in relation to properties of the fuel, combustion, and exhaust conditions. 4. Obtain data base of WHB design guidelines concerning fouling from several gas turbine engine exhausts.
