Abstract
PURPOSE: To test an interrupting valve during the boiler driving by testing the opening and closing of the fuel cut-off valve when the load of the boiler assumes a value lower than a predetermined value.
CONSTITUTION: When the load of a boiler is reduced to 50% or less, the opening and closing test of a fuel cut-off valve A is first carried out. When a "valve A test closing command" 5 is issued by a push-button operation, if "valve B is fully opened" at "boiler load of 50% or less", "valve A closing test" is carried out. After the lapse of a predetermined time from the issuance of "valve A test closing command", if "valve A closed" is not confirmed, "valve A accident alarm" 6 is issued. After the lapse of a predetermined time from the issuance of the "valve A test closing command" 5, if "valve A accident alarm" 6 is not issued, a "valve A test opening command" 7 is issued to carry out the test of opening the cut-off valve A.
