Future Fuel Use in U.S. Plants

We surveyed a number of industrial and commercial establishments in the U.S. for future changes in fuel usage. These establishments included metal, plastic and pharmaceutical plants. The study covered efficiency improvements, cogeneration and fuel switching.

Energy Consumption and Process Economics at Textile Mills

For DOE, we evaluated the energy consumption and process economics at four textile mills of foam finishing and conventional wet finishing. In a parallel study in the polypropylene industry, we compared the new technology of converting waste atactic polypropylene into oil and fuel oils by fluidized bed cracking with conventional disposal of waste plastics in landfills.

Energy Conservation in the International Steel Industry

For the Office of Technology Assessment, we evaluated the steel industry in the U.S. and abroad to identify the factors influencing the rate of adoption of various energy saving options such as continuous castings, basic oxygen furnaces, argon-oxygen decarbonization, and use of formed coke.

Demonstration Program for Energy Technologies

We assisted the Government of Egypt and aided in planning a five-year, nationwide field test demonstration program of energy technologies such as waste heat recovery, solar process heat, small wind energy conversion, and photovoltaics. A variety of industries were surveyed. For each technology, candidate sites and conceptual designs of energy systems were identified to prepare specifications for a tender offer.  We also participated in a bi-national committee to evaluate the bids and select a contractor to implement this project.

Utilization of Rejected Heat from a Nuclear Reactor

We evaluated the feasibility of various options for utilizing the heat rejected from a 2,400 MW nuclear reactor. These included piping reactors’ effluents off-site to near-by industry; on-site options such as Rankine-cycle power generation, heat pump augmentation and direct uses; as well as cooling towers. Technical, economic and institutional factors were considered for each option.

Slurrying Coal in Liquid CO₂

For a private company, we participated in developing an innovative technology for slurrying coal in liquid carbon dioxide. The project involved preliminary and detailed design of a 1 tpd pilot plant, its construction and operation, and system studies of potential applications.

Coal-Water Slurry Fuel in Low-Speed Diesel Engine

We analyzed the burning of coal-water slurry fuel in a low-speed diesel engine. The analysis included atomization, droplet evaporation, transport and chemical reactions in the gas and solid phases. The times for these processes were calculated to determine rate-limiting steps.

Biomass Fuels

We evaluated the potential of a number of biomass fuels and related combustion systems. These included the burning of agricultural wastes in a fluidized bed furnace, bagasse in a suspension-fired boiler, and wood chips and pellets in novel designs of wood stoves and central heating furnaces with automatic feeding systems.

Potential for New Technologies in Electric Utility Plants

For a number of electric utilities, we evaluated plant heat rates and the potential of emerging technologies. Such technologies included fluidized bed boilers, combined cycle coal gasification, cleaning, micronization and slurrying of coal, and microprocessor-based controls.

Energy Audits in Food, Chemical, and Petroleum Industries

In Egypt and Bangladesh, we conducted energy audits of numerous plants in the food, chemical and petroleum industries. We conducted walk-through inspections; collected data using our own instruments; and recommended improvements such as boiler tune-up, cogeneration, etc.

Industrial Energy Conservation

In Egypt and Bangladesh, we conducted energy audits of numerous plants in the food, chemical and petroleum industries. We conducted walk-through inspections; collected data using plant instruments and portable instruments that we brought to the plants; and carried out cost/benefit analyses. We recommended energy conservation measures such as cogeneration, burner controls, fuel switching, waste heat recovery and insulation.
