Advanced pulverized coal combustor for control of NO/sub x/ emissions. First quarterly report, September 24-December 24, 1980
The first quarter results under the Advanced Pulverized Coal Combustor for Control of NO/sub x/ Emissions Program (DOE Contract DE-AC22-80PC30296) are reported. A preliminary gas phase reaction model for predicting fuel NO/sub x/ formation during combustion of methane fuel has been constructed. Predictions of NO/sub x/ formation under stirred reactor conditions agree with existing experimental data. Thermal NO/sub x/ and coal reaction data will be developed and verified during the next reporting period. Progress has been made in formulating the changes necessary to upgrade the Acurex PROF code for use as the comprehensive data analysis tool in this program. The radiation modeling and the incorporation of the needed modifications into the PROF code will occur during the next reporting period. The idealized combustor was designed, and requests for bids to fabricate the combustor were submitted. Combustor fabrication will be completed during the next reporting period.

Appraisal of the use of geothermal energy in state-owned buildings in Colorado
An appraisal of the use of geothermal energy for space heating requirements for selected state-owned buildings in six communities in Colorado is presented. The appraisal addresses several components of a feasibility study for geothermal applications, including resource assessment, pipeline rights-of-way, well design and drilling program, conceptual engineering designs for retrofits of building heating systems, evaluations of economic feasibility, institutional requirements, and environmental considerations. Economic feasibility is determined from evaluation of four economic measures: a simple payback period in years; twenty-year annualized system costs (geothermal system versus conventional system); total twenty-year undiscounted energy savings; and total twenty-year present value energy savings. The results of the analyses of each feasibility component are finally ranked, using a weighting system, to arrive at an order ranking of the eleven state-owned buildings for overall feasibility. The relative total feasibility rankings and the absolute evaluations of economic competitiveness with the existing conventional-fuel heating systems show that several of the state facilities are likely candidates for conversion to geothermal hot water heating systems. The best candidate by far is the Colorado State Reformatory at Buena Vista. The geothermal resource at Buena Vista (Cottonwood Canyon and Chalk Creek) is a high quality resource with high water temperatures and …

CaO interactions in the staged combustion of coal. First quarterly technical progress report for the period September 23-December 31, 1980
It is widely recognized that alkaline oxides, especially CaO, can be most effective in capturing sulfur in-situ. It is equally well recognized that NO/sub x/ emissions due to fuel-bound nitrogen in coal can be effectively minimized with staged combustion. Both these aspects have been demonstrated separately at Battelle and other laboratories. It is the overall objective of this program to develop the basis for optimizing sulfur capture by CaO under staged combustion. Our approach to accomplishing this goal is via an experimental and interpretative study of the chemistry and interactions of CaO under simulated and actual staged combustion conditions. In staged combustion one fires first under reducing (fuel rich) conditions prior to oxidation in the second stage. Our studies wherein coals were treated with CaO, i.e., impregnated with CaO for pulverized coal firing, or mixed and pelletized with CaO for stoker firing, suggest that conditions prevail under which CaO is first converted to CaS prior to being oxidized to CaSO/sub 4/. Since CaS has a greater thermal stability than CaSO/sub 4/, it is therefore possible to fire at temperatures above 900/sup 0/C (1650/sup 0/F) and retain sulfur under proper stoichiometric conditions. The program is aimed at defining the chemistry and …

Corrosion Research Center of the University of Minnesota. Progress report, July 1, 1980-December 31, 1980
At present, the research ranges from the quantum mechanics of the corrosion unit reactions, organic and inorganic coatings, surface reactions on polymers, metals and semiconductors to high-temperature chemistry of interest to solar-energy conversion. A second objective of the Center is to increase the utilization of corrosion data by the technical community through education and through the dissemination of appropriately formatted information. At present, two projects are in the planning stage for the near future. One is a pedagogical symposium on corrosion in microelectronic components and systems; the other is a series of lectures and videotapes, as well as a workshop on cathodic protection.

Extended rate equations
The equations of motion are discussed which describe time dependent population flows in an N-level system, reviewing the relationship between incoherent (rate) equations, coherent (Schrodinger) equations, and more general partially coherent (Bloch) equations. Approximations are discussed which replace the elaborate Bloch equations by simpler rate equations whose coefficients incorporate long-time consequences of coherence.

GRPAUT: a program for Pu isotopic analysis (a user's guide). ISPO task A. 76
GRPAUT is a modular program for performing automated Pu isotopic analysis supplied to the International Atomic Energy Agency (IAEA) per ISPO Task A.76. Section I of this user's guide for GRPAUT presents an overview of the various programs and disk files that are used in performing a Pu isotopic analysis. Section II describes the program GRFEDT which is used in creating and editing the analysis parameter file that contains all the spectroscopic information needed at runtime by GRPAUT. An example of the dialog and output of GRFEDT is shown in Appendix B. Section III describes the operation of the various GRPAUT modules: GRPNL2, the peak stripping module; EFFCH2, the efficiency calculation module; and ISOAUT, the isotopic calculation module. (A description of the peak fitting methodology employed by GRPNL2 is presented in Appendix A.) Finally, Section IV outlines the procedure for determining the peak shape constants for a detector system and describes the operation of the program used to create and edit the peak shape parameter files. An output of GRPAUT, showing an example of a complete isotopic analysis, is presented in Appendix C. Source listings of all the Fortran programs supplied to the Agency under ISPO Task A.76 are contained …

Kinetics of NO/sub x/ formation during early stages of pulverized coal combustion. First quarterly report, 26 September 1980-28 December 1980
The first quarter results under the Department of Energy Contract DE-AC22-80PC-30295 are reported. A stirred reactor technique to simulate the early combustion environment of coal particles has been devised. An existing cold flow model has been modified to develop the operating conditions required for combustion experiments. A test matrix for the cold flow tests has been developed and the system readied for testing. The anticipated analytical measurement approaches to the combustion test phases of the program are also discussed. An initial reported set of gas phase reactions has been incorporated into the PROF code. Predictions of NO/sub x/ formation to date have exhibited good agreement with existing combustion data. Experimental data of thermal NO/sub x/ formation in the stirred reactor will be integrated with the kinetic model.
