Title: Innovations by John B Doyle

Introduction

John B Doyle is a notable inventor based in Littleton, CO (US). He has made significant contributions to the field of emissions control technology, holding a total of 7 patents. His work focuses on improving the efficiency and effectiveness of fossil fuel-fired boilers.

Latest Patents

Doyle's latest patents include a sophisticated SO.sub.x, NO.sub.x, and particulate removal system. This innovative method controls emissions from fossil fuel-fired boilers by utilizing a high-temperature fabric filter house equipped with an SCR catalyst. The system receives flue gases along with an injected ammoniacal compound and sorbent. The sorbent effectively reacts with the SO.sub.x, while the ammoniacal compound reduces the NO.sub.x in the presence of the SCR catalyst. By removing both SO.sub.x and particulates upstream of the SCR catalyst, the system mitigates issues related to SO.sub.2 or SO.sub.3 poisoning and the erosion and fouling of the catalyst caused by fly ash. This pre-treatment of sulfur oxides and particulates allows the heat recovery system to operate at a lower outlet flue gas temperature, resulting in improved energy recovery.
