Latest Patents: Among his latest innovations, McDonald has introduced a vapor generating technique that outlines a method of operating a vapor generating system. This system, featuring a once-through vapor generator, operates by generating wet vapor in the upper portion of the load range and superheated vapor in the lower portion. The innovation involves passing the generated vapor through an external and remote moisture separator, ensuring optimal vapor quality. Additionally, the superheated vapor is desuperheated by liquid injection as it travels from the vapor generator to the moisture separator.

Another notable invention is his blowdown apparatus, designed for the efficient removal of contaminants entrained within the boiler water of a vapor generator. This apparatus features a perforated blowdown pipe that is vertically oriented within the generator. A blowdown and drain connection is strategically placed near the lower end of the pipe, allowing for the expulsion of contaminant-laden blowdown fluid from the generator.
