monitoredseal air;b) one shut-off device with double seal and seal-air space between the two seals supplied with reliably1) moni-tored seal air;c) two shut-off devices arranged in series with an intermediate opening to atmosphere and monitoring equipmentto detect leaking flue gas;d) readily visible, tight blanking disc;e) one shut-off device situated between the section to be inspected and the induced-draught fan withreliably1) monitored sub-atmospheric pressure between the shut-off device and the induced-draught fan. In thiscase one monitoring criteria shall become effective which directly indicates the failure of the draught, e. g. bymeans of flow or air measurements. This induced-draught fan shall not be used for boiler operation during in-spection;f) Other equivalent means.The seal air pressure shall be monitored continuously e. g. by measuring the differential pressure between seal airand flue gas. The seal air pressure shall always be higher than the respective pressure on the flue gas side.NOTEOnly the seal air pressure need be monitored if the maximum possible flue gas pressure (gauge) is known for alloperating and upset conditions2).Where the seal air pressure is less than its fixed limit value, at least one locally positioned optical and acousticalarm shall automatically be tripped. The alarm shall be tripped so as to be recognizable by all personnel working inthe respective work area.The measuring points for seal air monitoring shall be arranged so as to give representative values for the seal-airspace even under unfavourable conditions, e. g. caking, dust deposition, leaking sealing elements.The closed shut-off devices shall be safeguarded against unintentional or erroneous opening. This means mechan-ical interlocking or similar means shall be required in addition to cutting off the auxiliary energy. The interlockingdevice shall be designed so as to withstand 1.5 times the design value
