Abstract
A fluid heating apparatus heats fluid in a passage to a target temperature. The fluid heating apparatus includes a fluid heating unit that heats the fluid, a fluid temperature measuring unit that measures a temperature of the fluid, and a pressure control unit that controls a pressure in the passage such that the pressure becomes equal to a target pressure. While the fluid in the passage is heated to the target temperature and when a temperature estimated from the thermal conductivity and specific heat is not increased, the pressure control unit increases the target pressure. According to a fluid heating method, when the fluid is heated by the fluid heating apparatus, the pressure control unit controls the pressure of the fluid such that the pressure becomes equal to or higher than a critical pressure.
