Abstract
A reactor chamber is positioned between a top array of heat lamps and a bottom array of heat lamps. At least one of the heat lamps forming the top and bottom arrays features a segmented filament such that power output along the length of the heat lamp differs. In one configuration, the heat lamp has a pair of high energy output regions spaced from each other by a lower energy output region. In some configurations, at least one of the heat lamps forming the top and bottom arrays is non-linear, such as U-shaped. In further configurations, a non-linear heat lamp has a segmented filament with segments or areas of different winding density.
