boiler smoke tubes

Construction and Working Principle of Scotch Marine Boiler

This boiler has numbers of smoke tubes. We already know that all are tubes placed horizontally and connects each other from the combustion chamber to the chimney. After fuel combustion, burned smoke passes through smokes tubes and then it enters the chimney. Like others, boiler Chimney is used to exhaust the burned gases and smoke out of the
