Steam Boiler Questions and Answers

2019-12-18 · Question: Boiler pressure In tanker vessels we use boilers for cargo heating. Lets say that steam pressure to deck line adjusted to 5 bar. What will be most economical? Boiler pressure adjusted to 7 bar or to 16 bar ? Answer: The higher pressure would be advantageous if the boiler is oil-fired, but the difference is hardly measurable.
