Abstract
Provided are a boiler and a method for stage change control of the boiler. The boiler includes a burner to generate a calorie necessary for producing hot water by burning air and gas, and a controller to perform a stage change control operation, when the number of times, in which the stage is changed, is equal to or greater than a reference number of times, for a predetermined time, based on information on occurrence of the change of the stage in the burner, while hot water is used.
Claims14
A boiler comprising:
- a burner configured to generate a calorie necessary for producing hot water by burning air and gas;
- and
- a controller configured to perform a stage change control operation, when the number of times, in which a stage in the burner is changed, is equal to or greater than a reference number of times, for a predetermined time, based on information on occurrence of the change of the stage in the burner, while hot water is used;
- wherein the burner is configured to be driven in multiple stages;
- and
- wherein the controller is configured to:
- perform the stage change control operation when the stage of the burner is changed from a first stage to a second stage;
- perform a first control operation until a reference time is elapsed from a time point at which the stage change control operation is started, and perform a second control operation after the reference time is elapsed;
- and
- change a target revolution per minute (RPM) of a blowing fan, which supplies the air to the burner, to a second stage control RPM from a first stage control RPM while maintaining the stage of the burner to the first stage, when the first control operation is performed.

A method for stage change control of a boiler, the method comprising:
- generating, by a burner driven in multiple stages, a calorie necessary for producing hot water by burning air and gas;
- and
- determining that the number of times, in which a stage in the burner is changed, is equal to or greater than a reference number of times, for a predetermined time, based on information on occurrence of the change of the stage in the burner, while hot water is used;
- determining that the stage of the burner is changed from a first stage to a second stage;
- and
- performing a stage change control operation that includes:
- performing a first control operation until a reference time is elapsed from a time point at which the stage change control operation is started;
- performing a second control operation after the reference time is elapsed;
- and
- changing a target revolution per minute (RPM) of a blowing fan, which supplies the air to the burner, to a second stage control RPM from a first stage control RPM while maintaining the stage of the burner to the first stage, when the first control operation is performed.
