The adjustable heat exchanger provides precise control of oven temperature in a pyrolysis reaction. The heat exchanger includes two sets of hollow non-circular discs, the discs of a movable set being interleaved with the discs of a stationary set. A first working fluid circulates through a heat source oven and through the hollow stationary discs, and a second working fluid circulates through the hollow rotating discs and a pyrolysis oven. The two fluids do not mix with one another, but are always completely separate from one another. Heat transfer depends upon the relative surface area of the rotary discs interleaved between the stationary discs. Minimum heat transfer occurs when the rotary discs are rotated to a position clear of the stationary discs, and maximum heat transfer occurs when the rotary discs are completely interleaved with the stationary discs.
