nuclear analytical techniques for on-line elemental analysis in industry proceedings of an advisory group meeting organized by the international atomic energy agency and held in espoo, finland, june a technical document issued by the international atomic energy agency, vienna, Nuclear techniques for the on-line bulk analysis of carbon in coal-fired power stations May Applied radiation and isotopes: including data, instrumentation and methods for use in Author: Brian Sowerby. On-Line Nuclear Analysis of Coal based on prompt neutron activation represents a technological breakthrough for real-time process control necessary for optimum efficiency in the use of coal. These analyzers are presently being installed to solve a variety of current problems in coal by: 3. The threshold for the production of MeV neutron inelastic scatter gamma-rays from carbon is MeV and the cross-section rises to about b at about 8 MeV ().The use of MeV neutron inelastic scatter gamma-rays is the most widely reported method for the bulk determination of carbon in coal and other by:
Then the applications of PGNAA are discussed for: (1) on-line bulk coal analysis, (2) nuclear oil well logging, (3) vitrified waste, (4) the analysis of sodium and aluminum in “green liquor. On-line/in situ monitoring of coal before is fed into a boiler is a necessity. A very few analytical techniques like X-ray fluorescence and prompt gamma neutron activation analysis are available commercially with enough speed and sophistication of data collection for Cited by: 5. The general feeling among users is that XRF is good enough for off-line analyses, but only the neutron/gamma systems are useful for on-line. Secondly, the coal analytics I am concerned with are more process analytical techniques than lab versions. This means that the pulverized coal fed to commercial boilers is one of the subsets of the. use of online coal analysis in today's competitive utility market environment. Controls Analyzers Utilities MCS Help on-line analyzer manufacturers understand utility motivations and problems Promote the integration of online coal analysis into boiler controls and optimization systems Facilitate communication among industry segments through papers.
Coal mine underground environment gases gas composition is very complicated, especially coal self-ignition different oxidation stage symbol of mine gas and release of period of reckoning produce of the coal mine enterprises poisonous and harmful gas production safety, caused great harm to the mine production period and needed after the reckoning mine air composition for Author: Yong Li, Yong Sun, Lian Cong Wang. Described herein are integrated systems for generating neutrons to perform a variety of tasks including: on-line analysis of bulk material and industrial process control (as shown in FIG. 1), security interrogation (as shown in FIG. 2), soil and environmental analysis, and medical diagnostic treatment. These systems are based on novel gas-target neutron generation which Cited by: The STA Simultaneous Thermal Analyzer (STA) is able to analyze coal and coke to obtain Proximate Analysis data – volatiles, fixed carbon and ash – using 10 to milligram samples. This paper demonstrates this utility using standard coal and coke samples. Introduction Proximate analysis has long been used to determine the rank of coals byFile Size: 1MB.
