Describe The Natural Circulation On The Water Tube Boilers

Boiler Types, Parts, Operation, Applicatio

According to the method of circulation of water and steam, the steam boilers are divided into natural circulation boilers and forced circulation boilers. (i). Natural Circulation Boilers: In natural circulation boilers, the circulation of water takes place naturally by the convection currents that set ups during the heating of water.

Natural circulation may be either free or accelerate

Natural circulation may be either free or accelerated. In a boiler with free natural circulation, the generating tubes are installed almost horizontally, with only a slight incline toward the vertical. When the generating tubes are installed at a much greater angle of inclination, the rate of water circulation is definitely increased. Therefore, boilers in which the tubes slope quite steeply

2019-11-13 · Natural circulation may either be free or accelerated depending upon the steepness of the angle of inclination of the generating tubes and the location of the tubes carrying the cooler water downward. Accelerated natural circulation boilers have very steeply inclined generating tubes. Forced circulation is a boiler configuration in which a pump
