Therefore natural circulation is limited to boiler with drum operating pressure around 175 kg/cm2. #2.Controlled Circulation In Boiler: If the Operating pressure of boiler is between 180 kg/cm2 to 200 kg/cm2 then circulation in boiler is to be assisted with mechanical pumps, to overcome frictional losses.
High Pressure Boiler | Water Tube Boiler High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell.During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.
