Progress is reported in research designed to evaluate benefits associated with control of the surface energetic properties of materials used in heat exchangers; and to identify preferred ranges of these surface conditions that minimize deposits of biological fouling known to deteriorate heat exchange efficiencies in seawater, brackish water and freshwater systems. The technical approach employed uses special diagnostic plates in novel flow cells where fluid flow conditions can be well-controlled, modifying the surface chemistry and surface energy of the plates with very thin coatings and examining the earliest events of biofouling caused by macromolecules and microbial organisms. An aquarium system described previously was equilibrated and some initial exposure experiments were carried out. Six silane compounds were used to coat germanium plates for coating viability experiments.

The results are reported of a technical evaluation of alternate fuels for the proposed oil and natural gas fired No. 3 boiler at the Minnegasco Energy Center (MEC) located in Minneapolis, Minnesota. This report has been prepared for the Department of Energy, Office of Fuels Conversion for their use in considering an alternate fuel exemption petition submitted by MEC. The fuels considered for the proposed boiler include oil, natural gas, bituminous coal, petroleum coke/coal mixture, refuse-derived fuel (RDF), coal-oil mixtures, and coal/oil dual fuel fired. The purchase of steam from the Northern States Power Company (NSPCo) was also considered as an alternative to construction of another boiler at MEC. Evaluation of each fuel included review of the overall plant design, estimates of capital and O and M costs, salvage value, useful life, and quantities of solid waste produced. The MEC supplies steam and chilled water to the downtown Minneapolis area for building heating and cooling using two presently owned and operated 200,000 lb/h oil/natural gas fired boilers. If the proposed boiler is permitted to burn oil and natural gas, it will be identical in design to the existing boilers. The evaluation showed that the use of oil, natural gas, coal, …
