The EMS Energy Institute’s Stationary Power Program builds on the Institute’s strong foundation in the study of fossil and biomass fuels and their utilization to address issues that concern those involved in the energy community: environmentally responsible development and utilization of our energy resources, efficient utilization of existing energy resources, and development of alternative fuels for the future.
We recognize that the energy community is extremely diversified and dynamic, consisting of private industries, governmental agencies, and utilities whose interests range from fuel development in the front end to flue gas cleanup at the backend. The Institute responds to the varied interests and goals of its customers by providing support in identifying and solving existing problems while providing the expertise and facilities to evaluate new technologies and fuels.
The Institute has on site a wide variety of pilot- and demonstration-scale coal preparation and cleaning equipment as well as bench-scale analytical equipment to evaluate the composition of solid and liquid fuels. The effects of various cleaning and preparation techniques on fuel quality, handleability, and combustion can be determined. The Institute has the capability to characterize selective physical properties and complete chemical composition of solid and liquid fuels using traditional and advanced methodologies. Fuels include:
The Institute has the capability to characterize and evaluate limestones as reagents in wet flue gas desulfurization systems and as sorbents in fluidized bed combustors for reducing SO2 emissions. The Institute has particular expertise in determining the qualities of limestones that make them attractive as a reagents/sorbents in a given system as well as the ability to evaluate limestones in a variety of on-site bench- to pilot-scale units.
The Institute has experience in all aspects of combustion systems from fuel storage and handling to the burner and the stack as well as total system integration. The capabilities of the Institute allow for technology development and evaluation on the demonstration scale. Specific areas of expertise include:
Determining combustion behavior is an integral part of evaluating a fuel, especially when developing new alternative fuels. The EMS Energy Institute has years of experience in conducting combustion tests firing fossil, biomass, and alternative fuels in conjunction with other fuels. Specific areas of research include:
The Institute has experience in evaluating biomass/opportunity fuels/carbon neutral feedstocks as boiler and gasifier fuels, including animal fats and proteins, vegetable oils, animal tissue, manure/litter, grasses/crop residues, wastes wood products, food processing wastes, waste seeds, refuse-derived fuels, sewage sludge, and biomass pyrolysis products.
The Institute’s stationary combustion emissions program encompasses the formation and control of pollutants from all types of boilers, firing a variety of fuels, and using multiple emissions control options. Areas of research include fluidized-bed, watertube, firetube, and stoker boiler systems; fossil and alternative fuels and waste products; wet and dry scrubbers; fabric and ceramic filters; low-NOx burner technology; selective and non-selective catalytic reduction; and CO2 capture technologies. Pollutants include SO2, NOx, fine particulate matter, trace metals including mercury, VOCs, and dioxin/furan TEQs.
Gasification studies are currently being performed in a circulating fluidized-bed gasifier and a laboratory-scale fluidized-bed reaction system (both atmospheric pressure) capable of gasifying a variety of traditional fossil fuels as well as biomass materials. The gasification systems are used to assess fuel and operating conditions on gas composition and yields and the performance of co-gasification of coal and biomass. In addition, a high-temperature entrained flow reactor is used to study pyrolysis and gasification kinetics, mineral matter transformations, and interactions of coal and biomass ash with refractory materials; and an issued batch fluidized bed reactor tests limestone samples for sulfur capture from power plant scrubber applications.
Stationary power systems research is focused on fuel characterization coupled with the utilization and emissions of these fuels in industrial and utility boilers. Research is conducted using a broad array of reactors, combustors, and boilers fully equipped with state-of-the-art-emission monitoring technologies. Stationary power systems research includes:
