Download or read book Chlorine in Coal written by John Stringer and published by Elsevier Publishing Company. This book was released on 1991 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Illinois basin coals have a chlorine content which varies from 0.1% to values in excess of 0.5%. The mean chlorine content of the coal being mined is steadily rising. Customers are already expressing some unease and contracts limiting the chlorine content of coal have been reported. This has potentially significant implications for the industry. The object of this Conference was to attempt to quantify the impact of coal chlorine content on a variety of coal-using technologies, and to identify new research which is necessary to allow a rational definition of the limits of chlorine content required for each technology. The distribution of chlorine in the Illinois Basin coals was considered, and the current state of knowledge of the forms in which the chlorine is present in the coal was reviewed. The release of the chlorine from the coal during its processing, and the forms in which it is present in the products was examined. This information permits an assessment of the viability of methods of removing chlorine, either in coal preparation or from the post-processing products.The effect of chlorine on the coal conversion and combustion processes, and on the balance of the plant was reviewed. The most important effects are on the corrosion of construction materials at both high and low temperatures. These proceedings should be of interest to power plant, corrosion, and chemical engineers, and to coal cleaning technologists and researchers.

Download or read book High Temperature Corrosion During Use of Chlorine written by and published by . This book was released on 1992 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to characterize the role of chlorine in coal on the high temperature corrosion processes which can occur in coal combustion and conversion processes. The experience include laboratory tests performed in well-controlled high temperature environments and field tests in industrial coal fired boilers. Evaluation of samples of boiler tubes which have been recovered from boilers which used both high and low chlorine coals does not indicate that the higher chlorine levels are associated with accelerated corrosion of either water wall tubes or superheater tubes in pulverized coal boilers. Laboratory testing of metal coupons in combustion gas environments produced from low sulfur, high chlorine coal IBC-109 and high sulfur-low chlorine coal IBC-101 has been performed at 700 and 800°C. Initial results indicate that more overall corrosion is produced in the high sulfur environment than in the high chlorine environment. Internal attack in the highly alloyed metals alloy 800 and 310 stainless steel is accelerated by the presence of chlorine in the environment, but the level of chlorine required to produce this attack has not yet been determined. Further testing at other temperatures and gas compositions is in progress.
Download or read book High Temperature Chlorine Corrosion during Co Utilisation of Coal with Biomass or Waste written by Xiaoyang Gaus-Liu and published by Cuvillier Verlag. This book was released on 2008-04-16 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass and waste materials are regarded as renewable energy sources which can reduce CO2 production and prevent environment pollution when they are co-utilized with coal in power plant facilities. A great fraction of biomass or waste is characterized with high chlorine content. Fuel chlorine can induce fast material oxidation on superheater or waterwall surface in power plant boiler. However, the mechanisms of chlorine corrosion are different in oxidizing atmosphere and in reducing environment, and the corrosion rate is influenced by deposit ash characteristics and flue gas composition. Based on experimental researches, this work gives a comprehensive explanation of the morphologies and mechanisms of chlorine corrosion in reducing and in oxidizing atmosphere under the interaction of flue gas and deposit ash. The behaviour of a wide spectrum of boiler materials on the chlorine corrosion is described. Furthermore, the influence of fuel characteristics on the chlorine deposition during combustion process is discussed and predicated. Practical guidance for the material selection and for the fuel combination is suggested.

Download or read book Behavior of Sulfur and Chlorine in Coal During Combustion and Boiler Corrosion written by and published by . This book was released on 1991 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to conduct laboratory experiments to clarify the mechanism of boiler corrosion, which may lead to solving the corrosion problem associated with the utilization of Illinois' high-sulfur and high-chlorine coal. The kinetics of the release of sulfur and chlorine species during coal combustion is being determined in the laboratories using temperature-programmed pyrolysis coupled with quadrupole gas analysis (QGA) and thermogravimetric analysis in conjunction with Fourier transform infrared spectroscopy (FTIR). Samples of boiler deposits and ashes from different locations in boilers using Illinois coal will be analyzed for mineralogical and chemical compositions to understand the relations among deposit compositions, coal compositions, and the gaseous species in combustion gases. The relationship between the level of chlorine in Illinois coal and boiler corrosion will be studied by experiments with simulated combustion gases under combustion conditions. Reduction of sulfur and chloride concentrations in the flue gas using additives will also be evaluated.
