Abstract:
The invention is a system for detecting the level of slag in a solid fuels gasification reactor. In this invention a pokerod is extended into the quench chamber of the reactor, and pulled back to a retract position, in a timed sequence. The timed sequence is initiated by an electronic controller unit, in combination with an air pressure regulator, a solenoid valve, a double chamber air cylinder, and two sensor switches. The end of the pokerod that moves into the quench chamber is designed to contact the solid slag without penetrating the material itself. If the pokerod makes contact with the slag material, the controller sets off an alarm to warn the operator of slag build up in the reactor.
