HIGH-PRESSURE PREHEATERS with heat transfer surface made of tubes 22 mm in diameter
So as to increase safe output of high-pressure preheaters, the construction of unified series of preheaters with heating surface made of tubes 22x3,5 mm in diameter was designed. This solution enabled to intensify heat transfer, to reduce metalconsumption and to increase preheaters compactness and reliability.
