Abstract: A fluid latent heat absorption electric induction heater is provided for raising the temperature of a fluid supplied to a fluid-driven turbine in a turbine-driven electric power generation system. The fluid latent heat absorption electric induction heater alternatively transfers heat to the fluid by induced susceptor heating, or a combination of inductor Joule heating and induced susceptor heating. The fluid may be water-steam for powering a steam-driven turbine or another fluid used in a phase change system for driving a fluid-driven turbine in a turbine-driven electric power generation system.

Abstract: Large steel ingot casting is accomplished with a top suspended induction heating device supplied with variable power and variable frequency from a power source. By the induction heating and stirring provided by the top suspended induction heating device, metal solidification advances progressively upwards from bottom to top, and the upper molten metal in a riser part compensates for shrinkage of the lower solidified metal in the main part. Inclusions are selectively moved out of the molten metal by a variable electromagnetic stirring force and the formation of casting defects is suppressed.
