Title: Gas burner with fan and swirl vane - has air pressure monitor detecting blockage of air passage
IPC: F23D14/72
Filed: 1975-07-26
Abstract: Gas burner comprises a burner housing (1) containing a fan (2) which feeds combustion air to the burner via a swirl vane (4) which is located between the fan and the burner nozzle. A pressure monitor (8) responsive to partial pressure is connected to the chamber (7) of the burner housing which is located between the air inlet and the fan, for monitoring the quantity of air supplied. When the swirl vane is blocked, obstructing flow of air, pressure builds up at the fan output until conveying pressure of the fan is reached, but then further conveyance ends and the partial pressure in the air intake chamber is lost. Absence of a blockage by dirt at the valve which partially closes the inlet opening can be detected, as the free cross-section of the air inlet is not divided into smaller individual slots like that of the swirl vane.
