Air Preheaters - Foster Wheeler Italiana

Air Preheating System designed andsupplied by Foster Wheeler ItalianaThe Crude Oil price increase in the past years has rendered particularly importantthe fuel consumption reduction in the refinery processesFoster Wheeler Italiana has a long experience in designing air-preheatingsystems. The first application is dated 1962 when, despite the low fuel cost, airpreheating systems were installed on two big process heaters of a new refinery innorth Italy.The fuel saving by preheating the comburent can be performed in several modes:- Preheating air with flue gases utilising fix type, rotary type or heat-pipe typeair pre-heaters.- Preheating air with hot fluids available in refinery such as low pressuresteam, process steam, and hot water.- Utilising oxigen-rich hot streams such as gas turbine exhaust.The most convenient solution shall be selected on a case-by-case basis, after anappropriate analysis of utility cost, plot area availability and type of unit. FosterWheeler Italiana has designed all types of air preheating system and therefore isin position to provide the most convenient and reliable solution for each project.A partial list of air preheating system installation by Foster Wheeler Italiana isherewith included.Page 1 of 4
