PURGE GAS SUPPLY SYSTEM FOR POWER PLANT FLUE GAS CONTINUOUS EMISSION MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/047872
Kind Code:
A1
Abstract:
A purge gas supply system for a power plant flue gas continuous emission monitoring system comprises a nitrogen generator system and a bottled nitrogen supply system. The bottled nitrogen supply system serves as a backup gas source for the nitrogen generator system. The nitrogen generator system comprises an air compressor system, a compressed air supply system, a PSA nitrogen generator (21), a nitrogen purification system and a nitrogen supply pipeline system. The bottled nitrogen supply system comprises a bottled nitrogen station (31), a gas supply pipeline nitrogen pressure transmitter primary valve (35), a gas supply pipeline nitrogen pressure transmitter (36), and a CEMS instrument purge gas inlet valve (37). The purge gas supply system prevents interruption of purge gas supply, and can continuously supply high quality purge gas to an analyzer, thereby ensuring that a lens of the analyzer is clean and dry, and accordingly ensuring that the analyzer accurately and stably monitors data.
