ERROR CORRECTION METHOD OF AIR PRESSURE SENSOR IN AIR PROPORTIONALITY TYPE BOILER

摘要

A method of compensating error of a wind pressure sensor in an air proportion control boiler is provided to prevent decrease of combustion efficiency of the boiler smoothly controlling a blower. A method of compensating error of a wind pressure sensor in an air proportion control boiler includes the steps of measuring a temperature in the boiler during a normal operation of the boiler(S1), determining whether an inner temperature of the boiler is increased more than a reference temperature(S2), determining whether an output value of the wind pressure sensor is within a compensation value range(S3), and compensating the output value of the wind pressure sensor when the inner temperature is in the compensation value range and outputting an abnormal signal when being higher than the compensation value(S6).
