Title: Innovations of James J. Hamill

Introduction

James J. Hamill is a notable inventor based in San Jose, California. He has made significant contributions to the field of power generation, particularly through his innovative patents. With a total of four patents to his name, Hamill has focused on improving the efficiency and functionality of dual fluid engines and boiler systems.

Latest Patents

One of Hamill's latest patents is titled "Method and apparatus for bypassing the superheater in a dual fluid engine." This invention presents an improved configuration for dual fluid steam-injected power generators. It incorporates a means to bypass the steam generated by the heat recovery steam generator (HRSG) around the superheater. This bypass allows for variation in the amount of superheat added to the injection steam used by the gas turbine. In an alternative configuration, the bypass means is placed between the turbine gas outlet and the superheater gas inlet. This design enables the hot turbine exhaust gases to be switched between the HRSG gas inlet and the superheater gas inlet. Additionally, Hamill describes a method for controlling the power output and the amount of steam generated by a steam-injected power generator.

Another significant patent is "Method and apparatus for improved start-up procedures in conventional systems." This invention provides an improved procedure for the cold start-up of closed-loop boiler sets and Cheng cycle systems. By utilizing an external pressure source to increase the operating pressure in the evaporator section, Hamill's method minimizes premature phase change and the accompanying volume increase, effectively eliminating the venting step, boiler swelling problem, and blowdown step of conventional start-up procedures.
