Document Description
The technical work of this project will first involve refining a demonstration plan and metrics. The output from this task will be used to design the package low swirl burner (LSB) for the boiler at a wastewater treatment demonstration site. The next task involves expanding the fuel sensor capability to allow for fuel switching. For use with biogas, the sensor will require modifications to the echo chamber and the emitter may also need to be changed. In addition, a thermal conductivity sensor will be added to allow the device to speciate mixtures of methane and higher hydrocarbons. A thermocouple will also be needed for the field test unit. This device will need to be then evaluated for response as a function of fuel composition and calibrated accordingly. Information from the fuel sensor provides the feedback to control the fuel air ration according to a set of control algorithm(s) so to maintain the same flame temperature in the boiler/combustor. The next task involves developing a control algorithm for fuel stock to be used in this project that is incorporated within software that utilizes a set of basic chemical kinetic reaction rate coefficients for natural gas and biogases. T he remaining tasks include: verifying the design of the components through reduced-scale prototype testing, constructing the full-scale unit, installing the unit, and conducting a demonstration.
