In addition, sometimes the evaporated liquid flowing down from the perforated plate does not flow down onto each tube of the heat exchanger tube group installed below the perforated plate due to pressure fluctuations above the perforated plate or clogging with foreign matter, etc., and instead flows sideways or diagonally. As a result, the evaporated liquid flows down the heat exchanger tube group without exchanging heat, resulting in poor evaporation efficiency and the formation of scale on the heat exchanger tube surface where the evaporated liquid is not exposed, which often impedes long-term safe operation. It was done.
