Title: Innovations of John E Bohan, Jr: A Flame Sensor Pioneer
Introduction
John E Bohan, Jr is a notable innovator based in Minneapolis, MN, known for his significant contributions to flame detection technology. With a remarkable portfolio of 19 patents, Bohan has consistently displayed a passion for advancing safety and efficiency in combustion systems.
Latest Patents
Among his latest inventions are two groundbreaking patents. The first, titled "Flame rectification sensor employing pulsed excitation," introduces a flame sensor circuit and method in which a generator injects periodic pulses of alternating voltage into the flame region. The voltage across the flame region is processed by a filter/amplifier, producing a non-zero output signal only when a flame is present during the excitation. This innovative approach enhances the reliability of flame detection, as it indicates failure of electrical components if unintended signals occur.
The second patent, "Burner control system with continuous check of hot surface ignitor," describes an advanced fuel valve and ignitor control system. This system utilizes a relay mechanism to ensure that the hot surface ignitor and fuel valve operate correctly by providing pull-in current through a series of relays. This design reinforces safety in burner operations by maintaining consistent control over ignition sources.
