Abstract:

The principle,main components and function of the fibre-optic image viewing system were described. The internal flame of combustor in different operating conditions can be observed using this system. The flame image was recorded and analyzed systematically.Some measures for improvement for test process were suggested. The viewing system can be an aid in the future design of more durable combustors.
