Abstract: A system for substance separation and energy recovery by thermal treatment is disclosed. The system includes a thermal treatment reactor, a circulation piping, a heat exchanger, a discharge pipeline, a latent heat recovering device, a gasifier, and a combustion furnace. The substance is fed into the thermal treatment reactor for heating the treated substance so as to produces a gaseous substance by evaporation or pyrolysis. The treated substance is separated into the gaseous substance circulating between the heat exchanger and the thermal treatment reactor and a residual substance being fed into the thermal treatment reactor. The increased gaseous substance, during the circulation process, is fed into a latent heat recovery device, wherein the gaseous substance exchanges heat with a cold fluid and condenses to release latent heat, forming a liquid condensed substance and a non-condensed substance.

Abstract: An electrostatic precipitator (ESP) intermittent energization controller is included with a CPU that adaptively controls the DC power used to energize the ESP. An opacimeter is mounted to the ESP for detecting the opacity of dust particles flowing through the same. The CPU searches through a table consisting of a predetermined number of charge-pause parameter sets until one charge-pause parameter set is found to cause the difference between the detected opacity level and the preset opacity level to be within a predetermined tolerable range.
