- The purpose of this project is to develop an advanced coal-combustion system for industrial boilers. With the new combustion system, coal could be used to replace oil and possibly gas as fuel for many industrial boilers. The advanced combustion system is comprised of several parts: (1) A new burner-design concept for coal fuels, developed from the familiar gas turbine combustor-can designs that have proven efficient, reliable, durable, and safe for the combustion of liquid fuel oils. (2) A coal storage and dense-phase feed system for injecting clean, ultrafine pulverized coal into the burner at a low velocity. (3) An automatic control system based on feedback from low-cost automotive combustion-quality transducers. A cold flow model of an initial phase of the new burner design and the associated laser flow-visualization techniques were developed during this quarter. A series of modifications of the initial cold flow model will be tested to establish details of design for the new burner. Also a 200 hp firetube boiler has been installed and tested using number 2 oil as a fuel. This boiler will be used for future combustion testing with the new burner and ultrafine pulverized coal. Additionally an ultrafine-coal injector has been designed which will be evaluated separately as a replacement for the oil gun in the firetube boiler. Two tons of deep-cleaned, ultrafine coal were received for initial tests with the coal injector.
