<strong>INTEC</strong> – <strong>Sales</strong> <strong>Meeting</strong>Date: Thursday, 26th of <strong>June</strong>, <strong>2013</strong>Venue:<strong>INTEC</strong> office building, BruchsalSpeaker:Mr. Rainer Keck, Design Director10:45-11:15 <strong>INTEC</strong> heaters and air preheaters2
Content <strong>INTEC</strong> thermal oil heaters– Different executions and special details <strong>INTEC</strong> air prehaters– Details and combinations with thermal oil heaters Examples for the arrangement3
Tube coil design codes Pressure Equipment Directive PED 97/23/EC with CE-Marking (design code AD-2000 rules) ASME B&PV code, Section VIII, Division 1 (U-stamp) Manufacture License of Special Equipment of P.R. China Marine certifications– GL, LR, BV, RINA, DNV5
Horizontal TO-Heater7
Horizontal TO-Heater Horizontal casing mounted on saddle supports Inner and outer coil anchored to casing on burner side End of combustion chamber equipped with refractorylining respectively oil-cooled turning plate Cover plate removable (optionally with door hinge) Thermal oil headers can be user-defined arranged Flue gas outlet located on rear end of casing or backwall Sight glass on cover and back side No drains and vents for tube coil8
Vertical TO-Heater(down-firing)9
Vertical TO-Heater(down-firing)10
Vertical TO-Heater (down-firing) Vertical casing mounted on a base frame Inner coil anchored to casing on top side, outer coilsupported on bottom side End of combustion chamber equipped with refractorylining respectively oil-cooled turning plate Cover plate removable (lifting tools) Thermal oil headers can be user-defined arranged Flue gas outlet located on lower end of casing Sight glass from cover side Drains for tube coil on bottom side11
Vertical TO-Heater (up-firing)12
Vertical TO-Heater(up-firing)13
Vertical TO-Heater (up-firing) Vertical casing mounted on a skirt or steel structure Inner and outer coil supported to bottom flange End of combustion chamber on top equipped with oilcooledturning plate Cover plate on bottom not removable (inspectionopening) Thermal oil headers can be user-defined arranged Flue gas outlet cone on upper end of casing Sight glass from cover side Vent system for tube coil on upper side14

Details of TO-Heater Fixing and spacer of the tube coils Oil-cooled turning plate Sight glasses on front and back side Hinged cover plate for horizontal heaters Cooling of the cover plate Inspection openings16
Fixing and spacer of the tube coils Single pipes of the coil fixedwith fillet welds Guard plates to protect thecoil pipes Spacers with short length toreduce heat stress17
Oil-cooled turning plate Defined turn-over of oil flowfrom outer to inner coil End of combustion chamber oilcooled No heat radiation reflection dueto refractory lining No risk of damages on therefractory lining Higher in price refractory lining Inefficient for small heaters18
Sight glasses Sight glass on each heater cover plate Sight glass on back side of horizontal heater All sight glasses with cooling air nozzle19
Hinged cover plate for horizontal heaters Opening without additional lifting devices 2 door hinges and adjustible heavy load supporting wheel Minimisation of internal gaps due to release mechanism Only to use for horizontal heaters (max. 4 starts coils)20
Cooling of the cover plate Reducing of head radiation for preheated air applications Cooling of the touchable surface Cooling of inner sealing plate due to air outlet into combustionchamber Reducing of cover plate weight21
Inspection openings Inspection openings on different areas of the heaters tofacilitate cleaning and maintenance work22
