ABSTRACT:
A kraft black liquor gasification system is provided with a hot flue gas generator which serves both as a means for generating a hot flue gas to warm-up the gasifier in preparation for start-up and as a means for generating an inert purge gas to purge the gasifier of flammable gases in the event of an emergency trip of the gasifier. A control system controls the operation of the burner during warm-up in response to the gasifier temperature and during the purge in response to the purge gas composition and temperature.
