Abstract
PURPOSE: To improve heat-transmitting efficiency and to enable the control of the amount of washing liquid, in a degreasing step or the like before paint- application, by supplementing a heat loss, caused by evaporation, with direct inhalation of steam and a heat loss, caused by cooling with a workpiece to be washed, with a combustion burner.
CONSTITUTION: Control valves 12a, 12b are closed or opened in response to the temperature of washing liquid, by a temperature detector 10, while other control valves 13a, 13b are closed or opened in response to the surface level of the washing liquid by a level gauge 11. Conseqently, the valves 12b, 13b are turned on to drive an in-liquid combustion burner 9 to heat the washing liquid, when the temperature of the washing liquid is below a fixed level and when the surface of the washing liquid is higher than a fixed surface level. When the liquid surface is lower than the fixed surface level, the control valves 12a, 13a are turned on, so that a steam-introducing means 8 is driven to heat the washing liquid with steam. Owing to this constitution, heat-transmitting efficiency is improved, the reduction of a transmitted heat amount derived from the adhesion of sludge or the like is inhibited, and the amount of the washing liquid can be controlled.
