Abstract |
This paper describes a newly-developed prototype of an electromagnetic induction flow-through metallic package-in-nonmetallic pipeline type fluid heating appliance, which is composed of series-loaded resonant phase-shift PWM inverter using IGBT modules in addition to an auto-tuning PID controller based the feedback implementation. This inverter-fed fluid heating appliance is to be more acceptable for high-quality heat energy transfer and delivery processing under a precise temperature management, as well as heat-energy storage and heat exchange processing plants as vessel and tank fluid heating in the pipeline systems, because of clean rocessing, high-efficient, compactness in volumetric size, high-relaibility, and best-matched control ability. The remarkable salient features of this inverter-fed fluid-heating appliance are presented as compared with the conventional electric heating methods. Its operating characteristics in steady-state are illustrated and evaluated in experiment and its computer simulation results. The promising applications of this fluid heating appliance are mentioned in this paper. |
