Radiating lamp fluid heating system

A system for heating a process fluid, including:

• a housing;
• a set of lamps mounted within the housing, for emitting radiation having a wavelength at least as long as infrared radiation;
• and
• chemically inert tubing mounted within the housing in a position separated from the lamps, for containing the process fluid while the process fluid absorbs radiation from the lamps, wherein the housing includes an end assembly having a spiral duct extending therethrough, each of the lamps has an end mounted in the end assembly, a chemically inert liner is positioned within the spiral duct, and the liner has a first end connected in fluid communication with the chemically inert tubing so that unheated process fluid flowing through the liner will absorb heat conducted from the lamp ends to the end assembly.

• chemically inert tubing mounted within the housing in a position separated from the lamps, for containing the process fluid while the process fluid absorbs radiation from the lamps, wherein the housing includes an end assembly, each of the lamps has an end mounted in the end assembly, and the end assembly includes a gas nozzles through which pressurized coolant gas may flow into the housing in order to cool the lamps, and wherein the end assembly includes:
• a plate through which the duct extends;
• and
• a chemically inert liner positioned within the duct, the liner having a first end connected in fluid communication with the chemically inert tubing so that unheated process fluid flowing through the liner will absorb heat conducted from the lamps to the end assembly.

A fluid heating system, including:

• a first end assembly, including a first end plate, wherein a duct extends through the first end plate;
• a second end assembly, including a second end plate;
• a set of lamps, each of the lamps having a first end attached to the first end plate and a second end attached to the second end plate, wherein each of the lamps emits radiation having infrared or longer wavelength;
• chemically inert tubing having a first end attached to the first end plate and a second end attached to the second end plate, wherein said tubing is positioned adjacent to but separated from the lamps, and wherein the tubing is dimensioned to contain process fluid so that the process fluid may flow through the tubing while absorbing radiation from the lamps;
• radiation reflecting material surrounding the tubing, for reflecting back into the tubing radiation that has propagated through the tubing from the lamps;
• and
• a thermally conductive, chemically inert liner positioned within the duct, the liner having a first end connected in fluid communication with the tubing so that unheated process fluid flowing through the liner will absorb heat from the first end plate before entering the tubing.
