LIQUID FUEL BURNER

PURPOSE:To make it possible to heat the air by the high temperature exhaust gas that is formed at the combustion section after combustion is started and reduce electric power consumption due to the use of an electric heater by providing an exhaust gas circulation means which mixes part of the high temperature exhaust gas produced in the combustion section with the air that is taken in and circulates the mixture. CONSTITUTION:When the operation is started and the combustion is started, the high temperature exhaust gas that is formed in a combustion section 50 is mixed with air in an exhaust gas circulation means (consisting of an exhaust gas channel 71 and a control valve 72) and the mixture gas is circulated, and the air that is sent to an evaporation chamber 20 is suitably heated by the high temperature exhaust gas. With this arrangement in the steady combustion except the initial stage of ignition right after starting the operation it can be continued without using an electric heating means 30 or with a small consumption of electric power. And, since the heating of the air by mixing the high temperature exhaust gas is direct, it is possible to heat the air by following without delay a rapid increase of fuel.
