2019-5-3 · the boiler, the flue gases make 1, 2 or 3 passes through the water stored in the pressure vessel. For a 2-pass boiler, there is only one bank of tubes, for a 3-pass boiler there are 2 tube passes and for a 4-pass boiler there are 3 tube passes. After leaving the convective section of the boiler, the flue gases exit the pressure vessel at the stack.
