AIR PRESSURE SENSOR ERROR DETECTING METHOD IN AIR PROPORTIONALITY TYPE BOILER

摘要

PURPOSE: A method for detecting an error of an air pressure sensor in an air-proportional type boiler is provided to control the operation of a boiler by detecting the correction of revolution per minute. CONSTITUTION: A method for detecting an error of an air pressure sensor in an air-proportional type boiler is as follows. The RPM of a blower is measured at in ignition and combustion of a boiler(S10). If the blower RPM decreases lower than a standard value, the operation error is not immediately marked, but the RPM of blower is compulsorily increased(S20). It is detected that the output value of the wind pressure sensor is proportionally increased relate to the forced increase of the RPM of blower(S30).
