Induction Heating System

Introduction: the systems of thermal effects on thermo-dependent, viscous and highly viscous liquids under conditions of the Arctic and the Extreme North are considered. Low efficiency and danger of heating systems based on burned hydrocarbons, heated liquids and steam are shown. Electrothermal heating systems used to maintain thermo-dependent fluids in a fluid state are considered. The evaluation of the effectiveness of the application of the most common electrothermal system — heating cables (tapes). The most effective electrothermal system based on induction technologies has been determined. Materials and methods: considered methods of thermal exposure to maintain the fluid properties of thermo-dependent fluids at low extreme temperatures. Results: presents an induction heating system and options for its implementation in the Extreme North and the Arctic. Conclusions: induction heating system to minimize loss of product quality, improve the system performance under changing process conditions, eliminate fire product, to reduce the influence of the human factor.

High Frequency Induction

The inverter power supply system has strong nonlinearity and parameter variability, especially in the non-linear loads, conventional control technology is difficult to achieve effective control and get the ideal control effect. Aiming at the control requirements of single-phase high-frequency induction heating inverter supply power control applications, uses a novel multiple and composite control technologies to achieve rapid power modulation control of inverter. The components and design principles of proposed control system were introduced in detail. The inverter power system model based on the new control strategy has been built, and inverter prototype used for high-frequency induction heating was designed. The experimental results show that the proposed control method to obtain better dynamic characteristics than the conventional control technologies, and has good advantages of system steady-state accuracy, robustness and control qualities, which has wide range of application.
