Abstract
A PAPER on the place of radiant, dielectric and eddy-current heating in the process-heating field was read recently in London before the Institution of Electrical Engineers by Messrs. L. J. C. Connell, O. W. Humphreys and J. L. Rycroft, in which the authors maintain that if the fullest advantage is to be gained from the rapid developments which have taken place in connexion with radiant and high-frequency methods of heating, care must be exercised in the selection of the applications for which they are recommended. Although many processes can be carried out more effectively by the new methods, there is still a very real place for contact and convective heating. The purpose of the paper is to facilitate this selection. The paper first reviews the various methods of heating, indicating the physical laws and practical considerations by which they are governed and the rates of heating which may be obtained. The types of application for which each process is best suited are then classified in terms of their technical requirements. Finally, several applications are considered in some detail, and it is shown that processes having superficial similarity may nevertheless possess features, not at first apparent, which are of sufficient importance to warrant the use of different methods of heating.
