Project Description

Tech4Imaging LLC will build a functional prototype of an Adaptive Electrical Capacitance Volume Tomography (AECVT) system for mass-flow gauging of solids circulating in high-temperature (> 750 °C) environments. AECVT is a newly developed technology that can provide 3-D imaging of multiphase flow behavior in real time. Devices that can accurately measure the solid flow rate of an operating gas-solid system would be of great aid for optimizing and controlling the combustion processes in advanced reactors. Presently, the availability of such devices, particularly at high temperatures, is very limited. In this Phase II effort, a functional prototype of an AECVT system for mass-flow gauging of solids circulating at high temperatures will be built. The intrinsic high measuring speed of capacitance measuring technology and high resolution capability of AECVT technology will enable such mass flow measurements at 5% spatial resolution and 1 Hz temporal resolution. Capacitance sensors exhibit favorable features of safety, flexibility, and suitability for scale-up applications that make them a favorable solution for industrial applications. Tasks, based on logical progressions from past experience of developing imaging systems; will focus on optimizing sensors, electronic hardware, and feature extraction software for hot flow applications based on AECVT technology.

Project Benefits

Successful completion of this Phase II project will provide a prototype of an AECVT system for hot temperature applications in harsh-condition reactors that can be extended to many energy-related applications. The proposed system would also advance multi-phase flow research of hot systems by providing access to obscure locations of a flow system. It also has a very high potential of attracting commercial interests as the need for advanced instrumentation is imminent to address the increased sophistication of advanced power plants. Hopefully by spurring economic growth, the public will benefit.
