Abstract: An improved apparatus and method is provided for removing microfouling from the tube side of a shell-and-tube heat exchanger on a more effective and efficient basis. The tube side of the heat exchanger is isolated and drained completely of surface water while it is still on-line. A source of low relative humidity air which is dry is provided. The low relative humidity air is passed through the tube side of the heat exchanger while there is still a heat load on the shell side of the heat exchanger. The surface water is re-introduced to the heat exchanger after the tube side of the heat exchanger has been dried so as to wash away and remove the dried out microfouling from the tube side of the heat exchanger.

Abstract: A method of blanketing a boiler with nitrogen to reduce the level of oxygen dissolved in water in the boiler. The method includes the steps of creating a nitrogen blanket in the boiler, then preserving the nitrogen blanket during the subsequent filling of the boiler, and providing sufficient contact in the boiler between the water and the nitrogen to maximize the reduction of the level of oxygen dissolved in the water.
