CONTROL METHOD CONSIDERING HEATING LOAD OF BOILER

摘要

The present invention relates to a combustion control method considering a heating load of a boiler. The purpose of the present invention is to prevent durability of the boiler from being reduced in advance and prevent noise caused by frequently opening and closing a magnet valve due to on/off being frequently generated when the boiler is combusted in a house of which the heating load is relatively small in comparison to a capacity of the boiler.
