Among these activities, which are usually focused on process improvements, are services such as:

Bias testing, stockpile sampling, and as-fired sampling for coal-burning public utilities and industrial boilers.
Power plant audits with sampling and analysis of all kinds of fuels, such as lumber mill waste, agricultural wastes, tires, steer manure, coal mine refuse, sludges, etc., to determine and improve plant operating efficiency and minimize waste.
Emission testing with evaluation and development of different emission-control methods.
Evaluation of traditional coal preparation plants and new fuel enhancement plants by sampling and analysis, process modeling, and overall process flowsheet review.

Fuels Characterization

hazen-research-admin — Mon, 10 Jun 2013 21:10:26 +0000

Characterization describes what a fuel is and how it can be effectively used. Since the establishment of our Coal Services Group in the early 1970s, 91�� has developed extensive capabilities for solid-fuels analysis, characterization, research, and process development. Many of the characteristics of coal or other fuels are determined using ASTM procedures or standard analytical methods for fuels. These include proximate and ultimate analyses, trace metal content, ash, ash fusion temperature, and materials-handling Ash Fusion Furnace characteristics that may have an impact on commercial application, e.g. flowability, bulk density, bridging, dusting, etc.

We have developed many specialized characterization tests for fuels and fuel additives, such as determining the "self heating" tendency of upgraded low-rank coals, evaluating various fuels for potential fugitive emissions, and determining the effect of additives on emissions and ash properties. Our experienced staff can determine how the composition of the mineral matter in a fuel will affect combustion performance (slagging and fouling) as well as the waste-handling characteristics and leachability of the ash. 91��'s Mineralogical Laboratory has the equipment, procedures, and staff for the characterization of raw fuels, ashes, slags, and partially burned residues. We use optical microscopy, scanning electron microscopy, and QEMSCAN analyses to examine the fine structure of fuels and the nature of contaminants. A fully equipped inorganic analytical laboratory is vital for determining major elements and trace metals in fuels, and ours has performed millions of analyses. These investigative methods are also used in the study of fuels other than coal, for instance oil shale and tar sands. The reliability and usefulness of modern characterization techniques are limited more by the validity of sampling methods and sample preparation than by the accuracy of laboratory procedures. 91�� has had extensive experience in sampling all types of fuels, large and small stockpiles of coal, unit trains, and power plant feeding systems. We have also developed unique methods for sampling and characterizing unusual fuels such as stockyard animal refuse, corncobs, tar residues, municipal wastes, wood byproducts, and grasses.

Introduction Copy:

One billion tons of coal are mined in the United States each year, and all of it must be sampled and characterized to determine its value and utility.

For thousands of years, the mechanical energy used by mankind came from animals and man's own muscles, with minor contributions from wind and water. It was not until the Industrial Revolution that the utilization of fuels and the efficient production of energy contributed in a significant way to man's progress. With the maturing of new energy technologies came the need for improved conversion efficiency and cleaner emissions.

The 1970's energy crisis triggered interest in the development of alternative fuel sources, including oil shale and biomass, and processes to utilize them. Today, "fuel" can be any one of a broad range of substances, including many that were previously considered wastes from agriculture, forestry, and manufacturing. Since 1961, 91�� Research, Inc. has played a significant role in developing energy-efficient processes, enhancing fuels, and reducing emissions from energy production and utilization. What we do is make fuels more usable to provide energy for mankind. Our Energy and Fuels Services, which center around the development of new processes and improvements to existing processes, include complete fuels characterization, laboratory and pilot plant testing, engineering, and field services.

Fuels and the processes that utilize them significantly affect the quality of our lives.
