Convection - answer-is the transfer of heat through space by heat ray. expanded tube joint - answer-is the tube-to-tube sheetjoint achieved by mechanical of explosive expansion of the tube into the tube hole in the tube sheat. conduction - answer-is the transfer of heat within a fluid material by actual movement of hotter molecules from one place to another. double tube sheet - answer-is a type of construction in which two (2) spaced tube sheets, or equivalent, are employed in lieu of the single tube sheet at one or both ends of the heat exchanger. tube sheet ligament - answer-is the shortest distance between adjacent tube holes in the tube pattern water - answer-is usually used when a heat exchanger is test cross bolt - answer-When flanging up heads, attention should be given to ------------- tightening to ensure even draw-up on the flange. outside diameter - answer-Tube OD refers to the measured ---------- of a tube downcomer - answer-is a part of the tray that is the vertical position which connects the tray to another, or the tower shell. draw off - answer-is a trough or depressed section of a tray which collects the liquid Straight Tube Heat Exchanger - answer- The convection section of a heater is located - answer-Above the radiant tube section Why do some tubes have fins - answer-to allow more heat transfer surface area ------ is a type of construction in which 2 spaced tube sheets or equivalent are employed in lieu of the single tube sheet art one or both ends of the heat exchanger - answer-double tube sheet construction what is the max percentage you can plug into a tube sheet? - answer-10% when flanging up heads, attention should be given to ------ lightening to ensure even draw up on the flange - answer-cross bolt ------ is a drought or depressed section of a tray which collects the liquid - answer-draw off Name them - IN ORDER NOT WITH THE LETTERS - answer-HandWheel Stem Gland Follower Gland packing bonnet body wedge seat ring blinding a furnace or a boiler is required before doin work on or inside the furnace. if the work assignment requires entering the furnace, then only certain lines coming into the furnace need to be blanked or plugged (T/F) - answer-FALSE Before beginning any work on an exchanger make sure that you have the proper work permit (T/F) - answer-TRUE Bolts, washers, nuts, clips and other items used to date trays together are called hardware (T/F) - answer-TRUE Make sure all parts are aligned before tightening, are the steps that should be taken to
