Title:
METHOD AND DEVICE FOR HEATING TO-BE-HEATED OBJECT
Document Type and Number:
WIPO Patent Application WO/2018/168160
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method and a device for heating a to-be-heated object, said method and device making it possible to uniformly heat the to-be-heated object in a short time, greatly reduce the generation of carbon dioxide, nitrogen oxides, etc., and allow drying and heating to be carried out efficiently in consideration of the environment. Provided are: a method for heating a to-be-heated object by supplying a fuel fluid (M1, M2) and a burn-supporting gas (G3) and using, as a heat source, a flame (2) obtained by combusting these, the method comprising gradually increasing the oxygen concentration in the burn-supporting gas (G3) supplied to the burner (3) and thereby increasing the rate of temperature increase of the to-be-heated object; and a device (1) for heating a to-be-heated object, the device (1) being provided with a burner (3) for heating the to-be-heated object, a flow rate control unit (4) for controlling the flow rates of the fuel fluid (M1, M2) and the burn-supporting gas (G3), and a computation unit (5) for transmitting combustion information about the burner (3) to the flow rate control unit (4). The flow rate control unit (4) gradually increases the oxygen concentration in the burn-supporting gas (G3) supplied to the burner (3) and increases the rate of temperature increase of the to-be-heated object.
