The combustion method of the vaporization combustion device comprises the following steps:

the liquid fuel is first delivered to the electric preheating zone by means of the high-pressure pump 1, and the electric preheater 7 is raised to a high temperature by means of the electric heating elements. The liquid fuel is converted into combustible gas after passing through the electric preheating zone. When the pressure increases with the formation of combustible gas and rises to a certain combustible gas pressure, the first valve 9 is opened. The gaseous fuel is delivered to the first cooking range 11 by display and monitoring of the first flow meter 6.
