Title: Method and equipment for treating ceramic
Inventor: IBURAHIMU SABURI BARUBAA
IPC: F27D99/00
Filed: 1992-02-20
Abstract: PURPOSE: To provide a method and a device which can efficiently process ceramic material, by combining a conventional heating means and a microwave heating means. CONSTITUTION: This device comprises a kiln 10 which has a heating chamber 14 separated by a perforated wall 22 from a secondary chamber 24, and the secondary chamber 24 houses a conventional heating means 26. The method is to raise the temperature of material to a desired temperature by applying conventional heat or radiative heat, and apply microwave radiation to keep the material at a desired temperature for a desired period. As a result, the method can process ceramic material more effectively because the ceramic material is heated until microwave coupling increases greatly by conventional heating means.  Since the method elevates the ambient temperature of the work space in the heating stage of the conventional method, the temperature gradient between the interior and the surface of the ceramic material in the heating stage by microwaves drops, and a high-quality product can be obtained.

Abstract: PURPOSE:To enable the correct sensing of the presence or absence of a flame by a method wherein a flame ground electrode with its one end being contacted to the main body of a burner is formed and arranged, and only an electric resistance of the flame is sensed except the non-combustion part even if the non-combustion part is produced. CONSTITUTION:One end of a flame ground electrode 5 is connected to an impeller 2 by strong fixing means such as welding etc., the other end is arranged to be positioned in the flame F formed by the ignition burner 1. In this case, it is sometimes found that the non-combustion part B is formed, so that the distance L is defined to cause the extremity end of the flame ground electrode 5 to be always positioned in the flame F. Presence or absence of the flame is sensed by detecting an air resistance between the flame electrode 4 and the flame ground electrode 5. If a presence of the flame F is acknowledged, the fuel is supplied to the main burner 8 and ignited. Thereby, irrespective of a presence or absence of the non-combustion part of the fuel, it is possible to detect correctly the presence or absence of the flame.
