SMOKELESS PYROLYSIS FURNACE WITH SINGLE THERMOCOUPLE, AND RAMP AND SOAK TEMPERATURE CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE A batch-type pyrolysis furnace fired by a main heat source such as a gas burner or an electric heating coil in combination with an afterburner to burn volatiles generat- ed in the furnace's main chamber, is operated to inciner- ate high-polymer loads smokelessy, yet is effectively safeguarded from explosions. A single thermocouple (zone TC) senses the instantaneous temperature in a critical sensitive zone (CSZ) of the furnace and in cooperation with a programmable controller (PC), maintains a presel- ected ramp and soak temperature profile over the entire burn cycle. The CSZ has been found to be within about 1' (foot) from the upper edge of the throat, and not lower than about 6" (inches) from the ceiling of the main chamber. When the temperature required by the profile is exceeded, a single water spray actuated by a signal from the PC lowers the temperature below the profile. The zone TC thus maintains a fire under controlled temperature conditions in the main chamber without an explosion, using a single TC in the control system.
