Abstract
Abstract A gas and vapor heater which is prefabricated at the shop in sections with the casing, refractory, coils and heaters all complete and unitized, whereby a plurality of such sections may be readily assembled together in the field with a minimum of welding and assembly time, and wherein each section has its heater coils disposed substantially horizontally and each section is of such a height that it can be readily transported by truck or rail to the field in the prefabricated condition.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
159 words
A gas and vapor heater, comprising: a plurality of prefabricated heater sections, each of such sections being shop fabricated and including: 1. a plurality of substantially horizontally disposed heating tubes, each of which is substantially U-shaped, and which are disposed at different elevations, one above the other, to form a vertical assembly of said tube; 2. a pair of substantially vertical headers having connection with the open ends of each of said heating tubes for circulating gas or vapor through said tubes; 3. a casing surrounding said vertical assembly of said tubes and having refractory material inwardly thereof to retain and reflect heat within the casing; and 4. heating means for supplying heat to the heater tubes within said casing; means for mounting said sections together, one above the other; and means for securing said sections together when mounted one above the other, said means for securing said sections together including welds for the adjacent edges of said headers.
Claim 2
Dependent Claim
