    Steam is passed through the tubes. Any air or gas moved over the tubes is heated. The condensing steam transfers heat more effectively than gases, so fins are fitted to the tubes to correct the imbalance and improve the heat transfer to the air or gas. Large steam air heaters are usually made of …
