Latest Patents

One of his recent inventions is focused on **steam generator control systems**. These control systems, designed for once-through, unfired steam generators, meticulously regulate the feedwater flow based on an energy balance between the hot gases provided to the boiler and the steam produced. This invention includes a predictive mode of feedwater control and an operator-selectable feedback mode to address any deviations in the predictive system. Moreover, the systems can incorporate predictive and corrective flow adjustments to ensure maximum efficiency, particularly beneficial in managing dual pressure boiler operations.

In addition, Campbell developed a **combined cycle power plant** boiler. This compact, unfired, staggered tube steam generator is specifically intended for use in combined cycle power plants, harnessing thermal energy from gas turbine exhaust gases. This advanced boiler design achieves steam generation at two pressure levels to optimize thermal energy recovery. The incorporation of corrosion-resistant materials in its construction reduces the maintenance burden by eliminating the need for pH control of feedwater and managing dissolved oxygen levels, allowing for automatic and unattended remote operation. Notably, the design mitigates flow instability commonly associated with once-through boilers, enhancing their operational reliability.
