Principles of Radio‐frequency Heating

Journal of the Society of Dyers and Colourists, 1982
The conservation of energy or the introduction of new techniques which will allow less energy to be used is an important area of activity for the Scarce Resources Committee. Accordingly, very successful half‐day symposia were held in 1980 to discuss the application of radio‐frequency techniques in textile processing.

Economic aspects of radio-frequency heating

Electrical Engineering, 1948
The importance of industrial applications of radio-frequency heating is emphasized by the growth of this field which has expanded into a business with an eight million dollar annual volume. Thus, an economic analysis of some of the problems including cost data in specific industries is of interest.

Radio-Frequency Heating in Food Processing

2004
Radio-frequency (RF) heating generally refers to dielectric heating in nonmetallic materials caused by electromagnetic energy ranging between 10 and 300 MHz (Orfeuil, 1987). An industrial heating system operating in the ISM (Industrial Scientific Medical) frequency bands at 13.56, 27.12, or 40.68 MHz (Table 1) is a well-established method for processing

Frequency-Selective Heating at Radio Frequencies

Nature, 1950
THE differential heating of the components of a heterogeneous mixture by radio-frequency fields is a well-known fact1,2, and the variation of the effect with frequency is often regarded as an important principle in various applications of radio- and micro-waves, for example, short-wave therapy and radio-heating.

Radio-Frequency Heating in the Woodworking Industry

Journal of Fluids Engineering, 1948
Abstract Radio-frequency heating is finding wide application in the woodworking industry for such processes as edge-gluing, plywood manufacture, drying, assembly-gluing. The theory of radio-frequency heating is reviewed briefly, and how this type of heat is applied in various applications is described.

Heating Wood With Radio-Frequency Power

Journal of Fluids Engineering, 1943
Abstract Radio-frequency power can advantageously be used to provide the heat required in various types of wood processing such as seasoning, drying, curing of impregnating materials, gluing, and bonding. This method is of considerable importance to the production of plastic plywood planes, boats, and housings of various types.

Dielectric heating by the radio frequency method

Journal of the British Institution of Radio Engineers, 1945
After a brief reference to some of the applications of radio-frequency energy to the heating of dielectric materials,the general theory of the method is outlined.The heat and power relations governing all such uses are discussed in some detail with special reference to sources of electrical and thermal loss in the generator and the work.

Radio-frequency heating of fusion plasmas

1998
VTT Energy co-ordinates the national FFUSION research programme and the Finnish activities in the European fusion programme. Finnish fusion research was integrated into the European programme by the contract of association between Tekes and Euratom, which defines the research areas of the Association Euratom-Tekes.
