PURPOSE:To make the temperature of a gasification cylinder stables by a method wherein a heat recovery for the gasification cylinder through a combustion heat is made excessive condition and an amount of cooling air to be supplied to a space between an outer circumference of the gasification cylinder and the cover of the gasification cylinder in response to a temperature of gasification cylinder. CONSTITUTION:When a combustion fan and an oil supplying device are operated to perform a combustion with a flame holding ring 4 and a temperature of a gasification cylinder cylinder is too inreased the temperature of the gasification cylinder is detected by a thermistor 57, control circuit 58 drives a motor 55, a damper valve 56 is rotated to increased an opening area of discharging pipe 54. As a result, the amount of cooling air for the gasification cylinder from an air chamber 53 is increased to cool the gasification cylinder and to prevent a temperature of the gasification cylinder from being increased. In case that a temperature of the gasification cylinder is too decreased, an opposite operation is to be carried out, and a temperature of the gasification cylinder can always be kept at a substantial constant value. |
