Combustion device capable of measuring gas use amount, and method for measuring gas use amount

A combustion device capable of measuring an amount of used gas comprising:

• a burner (220) configured to burn gas;
• a blower (230) configured to supply air for combustion to the burner (220);
• a gas valve (240) configured to supply gas for combustion to the burner (220);
• an air temperature sensor (270-2) configured to measure a temperature of air supplied by the blower (230);
• and
• a control unit (260) configured to control a number of revolutions of the blower (230), calculate a first amount of used gas which is amount of used gas when burning with a present operating heat quantity according to a signal input by a user, and compensate the calculated first amount of used gas inversely proportional with a measured gas temperature measured by the gas temperature sensor (270-2) to calculate a second amount of used gas which is a real amount of used gas.

A method of measuring an amount of used gas of a combustion device including a burner (120, 220) configured to burn gas, a blower (130, 230) configured to supply air for combustion to the burner (120, 220), gas valves (140, 150, 240) configured to supply gas for combustion to the burner (120, 220), and a control unit (160, 260) configured to control the burner (120, 220), the blower (130, 230), the gas valves (140, 150, 240), the method comprising:

• an operation of (a) supplying, by the gas valves (140, 150, 240) and the blower (130, 230), gas and air, and burning, by the burner (120, 220), the gas to supply a present operating heat quantity calculated based on a signal input by a user;
• an operation of (b) calculating, by the control unit (160, 260), a first amount of used gas which is amount of used gas when burning with a present operating heat quantity;
• an operation of (c) measuring, by a gas temperature sensor (170, 270-1), a temperature of the gas, and transmitting the temperature to the control unit (160, 260);
• and
• an operation of (d) compensating, by the control unit (160, 260), the first amount of used gas inversely proportional with a measured gas temperature measured by the gas temperature sensor (170, 270-1) to calculate a second amount of used gas which is a real amount of used gas.
