Stainless Steel Plate Air Preheater for refineries and petrochemical industries
Stainless Steel Plate Preheater is an advanced high efficient & energy saving type of preheater, which has the advantages of high efficient heat transfer, low pressure drop, compact structure, corrosion resistance, long service life, low soot accumulation, easy cleaning, etc. It can avoid not only the heat transfer tube burst due to high temperature, low temperature corrosion, easy block-up and premature failure of heat pipe heat exchanger, but also big volume and short service life compared with tube heat exchanger.
Stainless Steel Plate Preheater replaces the traditional tube and heat pipe by plate sheets as heat transfer components. Gas and air (coal gas) transfer heat through the plate sheets where the hot fluid and cold fluid are completely separated. The wall surface of the flowing channel keeps changing and results in enhanced turbulence of flowing fluid so that the performance of heat transfer is improved. Moreover, the plate sheet has a smooth surface and boasts lower fouling resistance.
