Thermodynamic Properties Of Alkali Species In Coal Based Combined Cycle Power Systems

Description: The aim of this project is to support the development of a concept for a successful alkali removal. Two strategies are possible: optimizing the alkali retention potential of the coal ash slag in the combustion chamber and the liquid slag separators and separate alkali removal with solid sorbents (getters) at temperatures below 1450 C. Therefore in a first step the alkali partial pressure over coal ash slag should be determined in order to get information about the retention potential of the sla… more

Radiative Properties of Ash and Slag

Description: Thermal radiation plays a key role in the operation and efficiency of combustion systems, accounting for over 90% of the heat transfer. The analysis of radiative heat transfer in coal-fired boilers, combustion chambers and other energy systems requires accounting for the effects of inorganic deposits on bounding surfaces and of entrained particulates, such as pulverized coal, char, and fly-ash. These effects can be predicted; however, the accuracy in predicting the radiative properties of entra… more

Small-scale, joule-heated melting of Savannah River Plant waste glass. I. Factors affecting large-scale vitrification tests

Description: A promising method of immobilizing SRP radioactive waste solids is incorporation in borosilicate glass. In the reference vitrification process, called joule-heated melting, a mixture of glass frit and calcined waste is heated by passage of an electric current. Two problems observed in large-scale tests are foaming and formation of an insoluble slag. A small joule-heated melter was designed and built to study problems such as these. This report describes the melter, identifies factors involved i… more

Advanced coal-fueled gas turbine systems

Description: Westinghouse's Advanced Coal-Fueled Gas Turbine System Program (DE-AC2l-86MC23167) was originally split into two major phases - a Basic Program and an Option. The Basic Program also contained two phases. The development of a 6 atm, 7 lb/s, 12 MMBtu/hr slagging combustor with an extended period of testing of the subscale combustor, was the first part of the Basic Program. In the second phase of the Basic Program, the combustor was to be operated over a 3-month period with a stationary cascade to… more

Optical properties of flyash

Description: In this research program, we have adopted the approach that by measuring fundamental properties (i.e, the complex refractive index, m) of the fly ash which participates in the radiation transfer, we can use well established theoretical principles (Mie theory) to compute the radiative properties of dispersions of fly ash as found in coal combustors. With this approach one can, understand the underlying principles that affect the radiative properties of an ash dispersion and more confidently pred… more

Coal ash behavior in reducing environments

Description: A key factor in the successful design and operation of coal gasification systems is the ability to control and mitigate ash-related problems. Some of the major ash-related problems are slag flow control, slag attack on the refractory, ash deposition on heat-transfer surfaces, corrosion and erosion of equipment materials, and emissions control. Such problems are closely tied to the abundance and association of the inorganic components in coal and the gasification conditions. The CABRE project is… more

Glassy slags for minimum additive waste stabilization. Interim progress report, May 1993--February 1994

Description: Glassy slag waste forms are being developed to complement glass waste forms in implementing Minimum Additive Waste Stabilization (MAWS) for supporting DOE`s environmental restoration efforts. The glassy slag waste form is composed of various crystalline and metal oxide phases embedded in a silicate glass phase. The MAWS approach was adopted by blending multiple waste streams to achieve up to 100% waste loadings. The crystalline phases, such as spinels, are very durable and contain hazardous and… more

Refractory failure in IGCC fossil fuel power systems

Description: Current generation refractory materials used in slagging gasifiers employed in Integrated Gasification Combined Cycle (IGCC) fossil fuel power systems have unacceptably short service lives, limiting the reliability and cost effectiveness of gasification as a means to generate power. The short service life of the refractory lining results from exposure to the extreme environment inside the operating gasifier, where the materials challenges include temperatures to 1650 C, thermal cycling, alterna… more

Rate of coal devolatilization in iron and steelmaking processes

Description: The devolatilization of coal particles under ironmaking and steelmaking conditions was studied. A new experimental technique was developed to measure the rates of devolatilization. A unique method was used to prepare coal particles based on thick coal bands rich in a given maceral group. Experiments with these single particles gave good reproducibility. The rates of devolatilization for all coal types from low to high rank coals were measured in the gaseous atmosphere and within the slag phase.… more

Evaluation of refractory materials for a nuclear waste incinerator

Description: An experiment to find a suitable refractory lining for a nuclear waste incinerator has been completed. Eleven brick and six castable products were analyzed by optical and scanning microscopy. All the materials were fashioned into cup shapes and subjected to temperatures ranging from 800 to 1200/sup 0/C for as long as six weeks. Some of the cups were charged weekly with pellets made from ash materials that would contact an incinerator liner. Refractory products containing a high percentage of al… more

Electronics system for transuranic waste assays

Description: A slagging pyrolysis incinerator has been proposed to reduce the volume of stored transuranic (TRU) waste material. This report describes the electronics developed for a fast TRU waste assay system using photon interrogation. The system uses a pulsed electron beam from a linear accelerator to produce a high-energy photon burst, termed the gamma flash, from a metallic converter. The photons induce fission in the TRU. A high-rate counting system is used to relate the production rate of photon ind… more
