Natural Circulation. In this circulation, the water flowing from upper drums through downcomers which is located in the boiler is relatively cold, flow down to mud drum. From mud drum, water flow back into the steam drum after passing through the evaporator tubes. Forced circulation. In this forced circulation, fluid is pumped through the
