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.

Infrared thermography has been developed as a tool to measure the temperature of various types of surfaces. Notable applications include thermal detection of buildings to detect heat losses. It was the intent of the NBS IR program to build on these technologies to assist energy conservation engineers to assess heat losses in industrial plants. Our intent in this project was to survey furnaces and heating systems in addition to electrical and mechanical systems to find areas suggesting energy conserving actions. This survey method described in this paper was carried out in fifteen industrial plants to develop a methodology and examine the feasibility of the approach. In addition to the qualitative survey quantitative data was gathered by calibrating the temperature of the 11 hot spots uncovered in the survey. This information was very useful in developing priorities and estimating the magnitude of the heat loss due to a given defect.

Excerpt from Elements of Thermography for Nondestructive Testing Thermography, the process whereby the invisible infrared thermal radiation from an object or a scene is rendered into a visible image, is known mainly for its military surveillance and remote-sensing applications. Nevertheless, thermography has great value also in a variety of non-military applications, and is being exploited in agriculture, geology, environmental control, meteorology, medicine, energy conservation, building, and manufacturing industry. In par ticular, its importance in industry for plant preventive maintenance, process control, quality control, and nondestructive testing has been recognized with the recent establishment of several independent working groups in thermography by different professional societies such as astm, asnt, and spie. This is intended to be a tutorial paper in thermography, espe cially as it relates to nondestructive testing, for program managers and scientists who are unfamiliar with thermal imaging systems and techniques, and who also may not have a background in infrared physics and technology. The material offered herein gives a simple, broad, and mainly qualitative overview which should help the reader to adjudicate the feasibility of applying thermography for his specific purpose. Notwithstanding, thermography is a highly sophis ticated and complex subject, and readers who wish to delve into the theory and the design of thermal imaging systems are referred to the books listed in the bibliography section. The bibliography includes also a listing of periodicals and reports dealing with applications of thermography to nondestructive testing.

This new up-to-date edition of the successful handbook and ready reference retains the proven concept of the first, covering basic and advanced methods and applications in infrared imaging from two leading expert authors in the field. All chapters have been completely revised and expanded and a new chapter has been added to reflect recent developments in the field and report on the progress made within the last decade. In addition there is now an even stronger focus on real-life examples, with 20% more case studies taken from science and industry. For ease of comprehension the text is backed by more than 590 images which include graphic visualizations and more than 300 infrared thermography figures. The latter include many new ones depicting, for example, spectacular views of phenomena in nature, sports, and daily life.

Infrared thermography (IRT) is a non-contact, non-invasive methodology which allows for detection of thermal energy that is radiated from objects in the infrared band of the electromagnetic spectrum, for conversion of such energy into a visible image (such as a surface temperature map). This feature represents a great potential to be exploited in a vast variety of fields from aerospace to civil engineering, to medicine, to agriculture, etc. However, IRT is still not adequately enclosed in industrial instrumentation and there are still potential users who might benefit from the use of such a technique and who are not aware of their existence. This e-book conveys information about basic IRT theory, infrared detectors, signal digitalization and applications of infrared thermography in many fields such as medicine, foodstuff conservation, fluid-dynamics, architecture, anthropology, condition monitoring, non destructive testing and evaluation of materials and structures. The volume promotes an exchange of information between the academic world and industry, and shares methodologies which were independently developed and applied in specific disciplines.
