PILOTLESS, UNPLUGGED COMBUSTION CONTROL SYSTEM

Номер: US20140165927A1
Автор: KALENSKY David C., Saveliev Alexei V., ZELEPOUGA Serguei
Принадлежит:

A self-powered combustion control system having a burner and a fuel supply control valve connected with the burner. The fuel supply control valve includes ignition and hold solenoids arranged whereby energizing the ignition solenoid causes the hold solenoid to transform from a closed disposition in which no fuel passes to the burner to an open disposition in which fuel flow to the burner is initiated for igniting the burner and subsequently maintained during heating of the material to be heated. An electronic system controller is provided for controlling the ignition solenoid and an unpowered rechargeable energy storage device is provided for all of the power required to operate the combustion control system. 1. A self-powered combustion control system comprising:a burner;a fuel supply control valve having a fuel outlet in fluid communication with said burner and having an ignition solenoid and a hold solenoid, said ignition solenoid and said hold solenoid operably linked, whereby energizing said ignition solenoid causes said hold solenoid to transform from a closed disposition to an open disposition;an electronic system controller for controlling said ignition solenoid operably connected with said ignition solenoid; andan unpowered energy storage device providing all power required to operate said combustion control system.2. The system of claim 1 , wherein said unpowered energy storage device is rechargeable.3. The system of claim 2 , wherein said unpowered energy storage device is a supercapacitor.4. The system of claim 2 , wherein said unpowered energy storage device is a battery.5. The system of further comprising an igniter for igniting said burner operably connected with said electronic system controller.6. The system of further comprising a flame presence sensor proximate said burner operably connected with said hold solenoid claim 1 , whereby heating of said flame presence sensor maintains said hold solenoid in said open disposition.7. The system of further ...

An exemplary embodiment can be an apparatus for real-time, in situ measurement of gas compositions and heating values. The apparatus includes a near infrared sensor for measuring concentrations of hydrocarbons and carbon dioxide, a mid infrared sensor for measuring concentrations of carbon monoxide and a semiconductor based sensor for measuring concentrations of hydrogen gas. A data processor having a computer program for reducing the effects of cross-sensitivities of the sensors to components other than target components of the sensors is also included. Also provided are corresponding or associated methods for real-time, in situ determination of a composition and heating value of a fuel gas. 1. An apparatus for real-time , in situ measurement of gas compositions and heating values comprising:a near infrared sensor for measuring concentrations of hydrocarbons and carbon dioxide;a mid infrared sensor for measuring concentrations of carbon monoxide;a semiconductor based sensor for measuring concentrations of hydrogen gas; anda data processor having a computer program for reducing the effects of cross-sensitivities of said sensors to components other than target components of said sensors.2. The apparatus of claim 1 , wherein said near infrared sensor comprises a first light source claim 1 , a first flow cell claim 1 , and a spectrometer.3. The apparatus of claim 2 , wherein said mid infrared sensor comprises a second light source and a second flow cell claim 2 , with said second flow cell positioned in a line with said first flow cell.4.
