Title: Monitoring system for a burner - is actuated by the pressure of the combustion chamber which is directly connected to the burner
IPC: F23N5/00
Filed: 1974-06-06
Abstract: The main part of the combustion is carried out within the combustion chamber which diverges towards the outlet of the burnt gases. The combustion gases emerge at a speed 50 metres per sec. from the combustion chamber. The pressure in the combustion chamber is measured and used as a command signal for subsequent combustion. Above a certain pressure a signal is produced indicating that the burner is on. When the pressure drops below this value the burner off signal is produced. The pressure in the outlet region is kept lower than that of the combustion chamber. The system ensures that combustion takes place reliably and prevents explosions.
