AI summary

A stable liquefied gas supply and heating apparatus includes an electromagnetic heating device installed at an outer bottom side of a gas storage tank to enable quick gasification of a liquefied gas in the gas storage tank into a target gas; a pressure control module and a temperature control module for monitoring the pressure and the temperature of the gas; and a heating control system for controlling the electromagnetic heating device to stably supply the target gas. The electromagnetic heating device includes an ON/OFF switch controllable by a gas supply system, the heating control system, and a gas monitoring system. Therefore, an operator can monitor and control the electromagnetic heating device from different independent spaces to avoid dangerous situations during gas supply, such as losing control of gas temperature and/or pressure or having an abnormal gas temperature.
