| 摘要 |
The steel boiler has a downwards-acting burner (5) in a combustion chamber (6), and a heat-exchanger (17) below the bottom (10) of the latter, through which vertical exhaust passages, and horizontal water passages (21) at different levels, pass. The water flows in opposite directions at successive levels. Adjacent to the combustion chamber the exchanger is purely of the contra-flow type, with its inlet (25) at the bottom on the burner axis, and an outlet (9) at the periphery.
