Answer»

Right answer is (c) Water CIRCULATION is limited inside boiler shell

To explain: Water circulation is limited inside the boiler shell. Water NEED not be that much pure and needs minimum treatment like passing through a pressure filter. Cleaning and repairing is not easy due to inaccessible parts, furnace cannot be ALTERED and is used for ONE fuel only.
