Arrangement of several gas calorific burners

摘要

The gas burner arrangement for burners (11) in a common furnace (12) includes a fan (12) for each burner. The valve body of the flue-gas valve is prestressed against its locked or closed position. During the operation of the burner, the flue-gas valve is held in the open position by an electromagnet. The open position of the valve body of the flue-gas valve is monitored by a position sensor, e.g. by terminal switches. The flue-valve may be fitted in an adaptor box held against the burner, to which the flue-gas line (2) is connected at the side.
