摘要

the invention of the first boiler commissioning heating pipe installed in accordance with the number of circulating heating supplements are made discloses a method to remove the air during start-up of the boiler is capable of removing effectively the foam of the air occurring. ; The main configuration of the present invention is the operation of the circulation pump for circulating a number of heating through the heating pipe, When a portion of the three-way valve to the heating operation can be supplied to the room is different from the operation mode according to the installation part is to be stored in the expansion tank of the boiler, for heating when the circulation pump is operating supplemented to make up for the number of heating in the heating pipe in the air during the start-up of the boiler As the air removal method removes sent to the expansion tank included in the number, when the replacement of the heating can be made, the operation start and stop of the three-way valve and the operation start and stop of the circulation pump With the time difference to be characterized by repeated periodically during the entire start-up time.
