Abstract (en)
[origin: EP1962017A2] The backflow prevention device comes into effect when the boiler is in excess pressure mode with several boilers using a common exhaust gas line, and each boiler has its own locking device for its input air line. This blocking device is in the form of a no-return valve (1) with at least one valve part (4) pivoted to a holding frame (3).
