Book excerpt: Excerpt from Applications of Thermography for Energy Conservation in Industry In addition to the qualitative survey, quantitative data was gathered by calibrating the temperature of the hot spots uncovered in the survey. These hot spots result from problems in the basic insulation design, flaws in the insulation and maintenance errors. However, many hot spots indicated malfunctions in the equipment such as leaking valves, leaking electrical components, failures in materials and components in invisible areas of the equipment, overheated bearings, etc. This information was very useful in developing priorities and estimating the magnitude of the heat loss due to a given defect. This approach applies the standard calibration methodology developed by equipment manufacturers for quantitative determinations of surface temperatures. Examples of this approach are featured-ih this report. A third technique has been explored with high energy consuming equipment such as furnaces. Here, the IR scan was used to survey the entire radiating surface of a furnace. Thermal mapping was combined with area measurements to determine total radiation heat losses. This information was then used as input data for a heat balance on the furnace. One experiment has indicated that approximately 30% of the heat consumed by the furnace is being lost from the surfaces by radiation. Further work is planned in this area to develop the method and will be reported in a later publication. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
