Title: Preparation of char as raw material for metallurgical coke
Inventor: MIYATSU TAKASHI
IPC: C10B57/08
Filed: 1980-03-31
Abstract: PURPOSE: To obtain good char capable of giving coke having a high strength and activity even on using as a raw material for molded coke in large quantities, by heat-treating a highly volatile noncoking coal under specific conditions.  
     CONSTITUTION: A highly volatile non-coking coal pulverized to a grain size, 80% or more of which passes through a -3mm screen, is heated from room temperature to 250W350°C, dried and preheated. The coal is then heated to 600°C or below at a  heating rate ≤15°C/min slowly and decomposed thermally to give a char, which is  then cooled to room temperature to 50°C. The drying and preheating treatment  provides uniform slow dry distillation treatment, and the thermal decomposition at  600°C or below permits the residual volatile contents to remain a little and prevents  the deterioration of an AP index. The excessive heating rate deteriorates the coke strength, and the heating rate is preferably 2W8°C/min.

Abstract: PURPOSE:To prevent an accident resulting from an electric shock by providing a device detecting existence and a location of a fixed component, such as a combustion cylinder so as to constitute release of a switch when the fixed component is not available or gotten out of the fixed location. CONSTITUTION:Under condition that a combustion cylinder 7 is placed on a guide cylinder a switching knob 12 is pressed to a full line location by the side of the combustion cylinder 7 and a switch 4 is closed. Then, an electric discharge igniter 2 becomes active through an operation of a switch 3. When the combustion cylinder 7 is disconneted from the guide cylinder 6 the switching knob 12 is displaced to a dotted line location for release of the switch 4. Therefore, regardless of an operation of the switch 3 an electric discharge circuit is not formed and the electric discharge igniter 2 does not become active. Thus, there is no fear of an electric shock at a time of an inspection and maintenance even if the switch 3 is operated erroneously and safety can be improved.
