Experimental and numerical study on induction heating performance of quaternary nitrate‐nitrite molten salt

Abstract

Summary Induction heating technology has been extensively applied in many industrial processes. The experimental system of electromagnetic induction heating molten salt is designed and built in this study; the molten salt electromagnetic induction‐heating unit is developed. The simulation results and the experimental data are in good agreement. The effect of molten salt inlet temperature, coil current, induction heater material and molten salt velocity are comparatively studied. The results show that the molten salt outlet temperature increases with the increasing of coil current and decreases with the increasing of molten salt velocity under same heating power. The heat absorption power of molten salt increases with the increasing of molten salt inlet temperature. The maximum molten salt heat‐absorption power in carbon steel condition is significantly 23.39% higher than that of stainless steel conditions. Meanwhile, the maximum heating efficiency of molten salt in carbon steel conditions is 16.7% higher than that of stainless steel. The maximum overall heat utilizing efficiency at Ts‐i = 292°C under different working conditions is 90.12%, which is 3.38% higher than that at Ts‐i = 200°C.

Experimental study on preheating and salt circulation performance of a single receiver tube based on induction heating

“…Researchers have studied the application of electromagnetic induction heating in the field of MS heating. Zhang et al 19 designed and constructed an experimental low-melting-point MS electromagnetic induction heating system. Experiments and numerical studies were conducted to analyze the influence of various parameters on heating efficiency and heat loss rate.…”

Implementation of Boost PFC in the Induction Heating System for EMI–RFI Suppression

“…The IH principles are useful in domestic cooking purposes as it has more advantages over the conventional methods [4][5]. Induction heating equipment also attenuates the injection of current harmonics with the help of interface filters [6][7][8]. Thus, there are great prospects of the growing use of IHE which are of high frequency in the upcoming days.…”
