BURNER
Document Type and Number:
WIPO Patent Application WO/2014/167737
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a proportionally controlled burner that omits as many mechanical components as possible, reducing power consumption, and minimizes the amount of heat lost via a flue. To that end, in the present invention, a high-speed solenoid valve (11) is provided in a fuel-supply system (Lf); said high-speed solenoid valve (11) has the ability to open when an inputted pulse signal is on and close when said pulse signal is off; an oxygen-concentration sensor (80) that is located on the combustion-exhaust side and measures the oxygen concentration of a flue gas is provided, as is a control device (60) to which measurement results from said oxygen-concentration sensor (80) are sent; and said control device (60) has the ability to change the frequency of an inverter (50) and regulate the amount of combustion air such that the flue-gas oxygen concentration detected by the oxygen-concentration sensor (80) approaches zero.
