Water tube boiler

HKB boiler solutions' water-tube boilers are designed as single-drum, high-pressure steam or hot water boilers with either natural or forced circulation. The design is based on the principles of the so-called corner-tube boiler. The capacity of the water-tube boiler can range from 5 to 120 t/h of steam, with an operating pressure of between 0

Natural Circulation - an overview | ScienceDirect Topics

Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3. Heat is applied to one leg, called the raiser tube, where the water–steam mixture flows upward.

3 Types of Circulation In Boiler - Water Treatment Basics

Water-tube boilers may be classified as NATURAL CIRCULATION BOILERS or FORCED CIR- CULATION BOILERS. In natural circulation boilers, the circulation of water depends on the difference between the density of an ascending mixture of hot water and steam and a descending body of relatively cool and steam-free water.
