Book excerpt: To burn coal most efficiently and cleanly, much smaller particle sizes are needed than can now be ground economically. This project was performed to demonstrate the technical feasibility of using ultrasonics to enhance grinding below the standard plant grind of 75 microns, and to extrapolate from this laboratory work the ultrasonic energy requirements for production use. Successively improved laboratory arrays demonstrated a repeatable production of particulates from 2000-micron coal to the desired size ranges (approximately 35% below 7 microns, 95% below 44 microns) with selective liberation of ash and pyrite inclusions to facilitate removal, with equipment translatable to production use, and the possibility of only 37 kwh/ton energy input requirement.

Book excerpt: Experimental work was conducted in the following areas: (1) moist grinding with and without ultrasonics; (2) tests of pyrite selective liberation; and (3) fabrication and assembly of the dual-roller apparatus. Using a water spray as a moistening agent, grinding was performed with the cylinder-segment apparatus. A 13:1 increase in -7 micron fines resulted. A more accurate iron determination method (ASTM D2492-68) was applied to two samples of well-characterized coals, enabling an expansion of the data on the degree of preferential liberation of inclusions attributable to ultrasonic comminution. A 5:1 reduction in pyritic iron occurred with ultrasonic grinding of the two coals tested. The dual-roll apparatus was completely assembled and aligned. Preliminary grinding was begun to determine basic parameters and to check out the equipment.

Book excerpt: Work focused on establishing experimentally determined parameters for ultrasonic comminution and their translation into the design of an ultrasonic comminution array for Phase I testing. Early work indicated that continuous removal of fines during communition could significantly increase the production of -10 micron particles. Similarly, varying the mechanical gain of the ultrasonic comminution apparatus and thereby increasing the strain amplitude of the system was shown to enhance fines production. A gain of 3:1 (i.e., a three-fold increase in strain amplitude) produced the best results. These features used with an ultrasonic cylinder segment apparatus resulted in 276% increase in the production of -10 micron fines over that generated by passing coal through a non-activated control. Thus influenced, the design of the Phase I ultrasonic comminution apparatus will incorporate both a dual-roll and roller/plate capability; it will provide continuous flow of particles through the region of ultrasonic activation, thus permitting removal of fines as they are comminuted; and will function with a gain of 3:1. The Phase I apparatus also offers the flexibility of operating with either traveling or standing ultrasonic waves. Varying the physical configuration (dual-roller or roller plate) and the mode of ultrasonic activation (traveling or standing wave) allows for cost effective testing of four different techniques. Additionally, operating frequency has been reduced to 15 kHz to permit use of off-the-shelf hardware in apparatus assembly and thus expedite testing. Selection of four representative, well-characterized coals has been completed; after initial testing, 200 lb. quantities of two of the samples will be secured for Phase II experimentation.

Available in PDF, EPUB and Kindle. Book excerpt: New Trends in Coal Conversion: Combustion, Gasification, Emissions, and Coking covers the latest advancements in coal utilization, including coal conversion processes and mitigation of environmental impacts, providing an up-to-date source of information for a cleaner and more environmentally friendly use of coal, with a particular emphasis on the two biggest users of coal—utilities and the steel industry. Coverage includes recent advances in combustion co-firing, gasification, and on the minimization of trace element and CO2 emissions that is ideal for plant engineers, researchers, and quality control engineers in electric utilities and steelmaking. Other sections cover new advances in clean coal technologies for the steel industry, technological advances in conventional by-products, the heat-recovery/non-recovering cokemaking process, and the increasing use of low-quality coals in coking blends. Readers will learn how to make more effective use of coal resources, deliver higher productivity, save energy and reduce the environmental impact of their coal utilization. Provides the current state-of-the-art and ongoing activities within coal conversion processes, with an emphasis on emerging technologies for the reduction of CO2 and trace elements Discusses innovations in cokemaking for improved efficiency, energy savings and reduced environmental impact Include case studies and examples throughout the book
