Finite-Difference Thermal Analysis of an Insulation System on a Precipitator Building in a Power Plant

Source

Little attention has been given in the literature to the analysis of thermal energy losses of large fabric filter houses and precipitator buildings. Either a fabric filter house or precipitator building is a major part of most coal-fired power plants. The function of the structure is to remove particulate matter from the hot flue gas and to maintain the temperature of the flue gas. Special insulation systems are designed to cover the structures and to meet the owner's requirements for thermal performance, long-term durability, and cost. One such system is described and thermally analyzed by using a finite-difference computer program. It should be noted that the analysis requires a large-capacity, high-speed computer. Selection of the thermal analysis procedure is discussed for determining the input values for the thermal analyses. Proposals are made for improving future thermal analyses.
