Combustion of dense streams of coal particles (open access)

Combustion of dense streams of coal particles

Research on coal combustion continued. Activities during November 29, 1991 to February 28, 1992 includes: Further analytical results on char array combustion and internal ignition of porous char; preliminary runs using a flat flame burner have been made and a blue flat flame has been obtained; a CID camera, EPIX frame grabber and software, Sony monitor and a 486 Computer to handle image processing frame by frame have been acquired; a new coal feeder has been constructed for feeding through the flat flame burner. Coal experiments have not yet been conducted. Coal samples from Penn State Coal Bank were also acquired for use in the experiments. They include bituminous and subbituminous coals of differing VM.

Comparison of Total Cooling Provided to the Energy Released After Low Current Quenches of SSC Dipoles in MAGCOOL (open access)

Comparison of Total Cooling Provided to the Energy Released After Low Current Quenches of SSC Dipoles in MAGCOOL

The performance of the MAGCOOL cryogenic system after low current strip heater quenches of SSC dipole has been investigated. For quench currents between 2000 and 4000 amperes, the loop pressure after a quench does not exceed the set pressure for venting. Excellent agreement between total cooling and the magnetic stored energy is found for each of the several values of quench current. The results indicate that the measurements are accurate and he method of calculation appropriate.

Instrumentation of dynamic gas pulse loading system (open access)

Instrumentation of dynamic gas pulse loading system

The overall goal of this work is to further develop and field test a system of stimulating oil and gas wells, which increases the effective radius of the well bore so that more oil can flow into it, by recording pressure during the gas generation phase in real time so that fractures can be induced more predictably in the producing formation. Task 1: Complete the laboratory studies currently underway with the prototype model of the instrumentation currently being studied. Task 2: Perform field tests of the model in the Taft/Bakersfield area, utilizing operations closest to the engineers working on the project, and optimize the unit for various conditions encountered there. Task 3: Perform field test of the model in DGPL jobs which are scheduled in the mid-continent area, and optimize the unit for downhole conditions encountered there. Task 4: Analyze and summarize the results achieved during the complete test series, documenting the steps for usage of downhole instrumentation in the field, and compile data specifying use of the technology by others. Task 5: Prepare final report for DOE, and include also a report on the field tests completed. Describe and estimate the probability of the technology being commercialized and in …

An integrated bremsstrahlung safety shutter and collimator designed for the APS front end operating in the top-up mode (open access)

An integrated bremsstrahlung safety shutter and collimator designed for the APS front end operating in the top-up mode

The Bremsstrahlung safety shutter is an important device for synchrotron radiation facility personal safety. The APS front ends have double redundant safety shutter assemblies (as per PSAR requirements) that are located about 22.6 m from the source, just upstream of the ratchet wall. These assemblies are needed to guard against an accidental positron beam loss during injection and normal operation, which then can result in high energy Bremsstrahlung radiation being directed down the front end into the First Optics Enclosure (FOE) and the experimental station. In the APS top-up mode of operation, the positron injection will be continued during the normal operation. Therefore, it is necessary to have special Bremsstrahlung shielding to protect the downstream experimental area. There are many ways to do this, but the most economical way is to design a special long Bremsstrahlung collimator in the front-end area. The better the collimation in the front end, the less the shielding material needed in the beamline. The major difficulty in designing the front-end special Bremsstrahlung collimator is the space problem. In the APS, the total length available for the APS ID front end is only about 7.6 m; there is not extra space for additional collimators. To solve …
