IPC: F23L15/02
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To maintain continued combustion of burners by preventing the occurrence of abnormality in other heat exchangers than those in which abnormality has occurred. SOLUTION: An exhaust path 6 is provided with a stack damper 7 normally closed being allowed to control the opening or closing thereof. It is judged whether abnormality occurs in a heat exchanger of each rotary regenerative burner RRX or not based on measured values of a temperature sensor TIA for measuring the temperatures of exhaust gases discharged from the heat exchangers and a measured value of a current sensor XA for measuring current fed to a motor M used as drive source of a rotation drive mechanism of the heat exchangers. When the occurrence of the abnormality is detected, the stack damper 7 is opened while an induction blower 11 is stopped and an induction blower damper 11a is closed. Thus, the rotary regenerative burners RRX operate as normal burner requiring no preheating of an oxidizing agent with any heat exchanger.

Abstract: PURPOSE:To simplify a production process and to shorten production time by providing an exothermic layer consisting of a material which generates heat during curing and heating a recording layer by making use of the heat generated by the exothermic layer so that the recording layer can be preliminarily crystallized. CONSTITUTION:A UV-curing is coated on a substrate 1 consisting of a synthetic resin and a member which is preliminarily recorded and formed with guide racks and preaddresses is pressed thereto. UV rays are then irradiated thereon to cure the UV- curing resin. As a result, the guide tracks and preaddresses are transferred thereto and a guide track layer 2 is formed. TeO2 and Te are simultaneously formed by electron beam vapor deposition in a vacuum on the guide track layer 2. The UV-curing resin is coated on the recording layer 3 by a roll coater to form the exothermic layer 4. The UV rays are irradiated on the exothermic layer 4 to cure the same. Since the exothermic layer 4 contains a large amt. of multifunctional monomer and a relatively large amt. of reaction initiator, said layer generates heat during curing. The disk is rested in a room of an ordinary temp. after curing of the exothermic layer 4 and therefore the recording layer 3 is heated up by the heat generated by the exothermic layer 4 and is then slowly cooled.
