Latest Patents

One of Shade's latest patents is focused on an economizer recirculation system designed for low-load stability in heat recovery steam applications. This innovative recirculation apparatus is employed to recirculate a portion of the feedwater in a vertical-tube economizer. It aims to reduce the likelihood of reverse flow and steaming during startup and low load conditions. The system includes a recirculation valve that directs part of the water from the economizer outlet back to the inlet of the boiler feed pump via a deaerator. This recirculated water increases the pumping head across the economizer tube planes and reduces the temperature rise of the increased water flow rate.

Another significant patent involves the use of sidewall baffles in heat recovery steam generators. In non-contact heat exchangers, the performance efficiency is heavily reliant on the full utilization of available hot gas flow. Shade's discovery that gas flow along the heat exchanger sidewalls results in unacceptable heat loss has led to the development of sidewall baffles that correct this issue. These baffles are designed to avoid alignment difficulties, thereby enhancing the overall efficiency of the heat recovery steam generator.
