Trace metals are usually inevitably contained in wastes, coals and so forth. When the wastes and/or coals are burnt, pollutants like NOx, SOx, soot, particulates, dioxins and heavy metal compounds are emitted from the furnaces. Some of the heavy trace metal compounds condense on the particle surface and/or form fine particulates during the combustion/incineration processes. Owing to the difficulties in capturing those fine particulates by means of conventional dust collection systems, those particulates tend to be exhausted into the atmosphere. In this study, fundamental behavior of the vaporization of Pb, Cd and Cr compounds was studied at relatively low temperature. In this experiment the effects of temperature and reaction atmosphere on the vaporization behavior of Pb, Cd and Cr compounds were studied using a thermobalance. The chemical thermoequilibrium calculation for each compound was also carried out in order to validate the experimental results obtained. As a result, the vaporization behavior of the metal compounds appears dependent on their respective melting points. Most of chlorides were easily vaporized at relatively low temperatures. This suggests that the presence of HCl enhances the vaporization of metal compounds, while coexistence of SO2 shows inhibition of the vaporization tendencies of Pb and Cd compounds. All of the Cd compounds vaporized in the reducing conditions. The results of chemical thermoequilibrium calculation agreed closely with the experimental results obtained.

Publishing type：Research paper (scientific journal) Publisher：The Japan Society of Mechanical Engineers

Particle size and composition distributions of ash particles in both reacting coal and depositing layer are analyzed, using CCSEM (Computer Controlled Scanning Microscope), to study behaviors of ash particles included in the reacting coal and deposition phenomena. For the behaviors of ash particles in the reacting coal, fraction of the coarse particles gradually increases due to coagulation, so that the composition of the coarse particles also changes during evolution and combustion processes of volatile matter. For structure of the deposit layer, on the other hand, fine particles of size less than 3μm mainly consist of the initial layer for three types of coal, and the thickness was about 30μm. Growth behavior of the deposit at the stagnation depended on the coal type. The deposition phenomena take place due to preference of both particle size and composition.

52 Coal Type Dependence of Formation Behavior of Fine Particulate Containing Alkali Metal Compounds

Some metal compounds in coal vaporize and form fumes during the combustion. The fumes are usually contained in the exhaust gas. For coal-fired combined power generation systems such as pressurized fluidized bed combustion, hot metallic vapors are introduced in a gas turbine. As this phenomenon causes corrosion problem of the turbine blades, it is necessary to control the formation of those fumes, which include alkali metal compounds. In this paper, the evolution behavior of alkali metal compounds, especially for sodium compounds, has been studied, using a drop tube furnace with a low-pressure impactor. As a result, concentration profile of sodium in the fine particles has dependence on coal type. On the other hand, the condensation mechanism of sodium seems to be similar in each coal.

In order to enhance the overall thermal efficiency in blast furnace system as well as coal gasifiers, it is necessary to elucidate fundamental reaction characteristics of pulverized coal at high temperature. The experiments were carried out using a horizontal pulverized coal reactor with a pre-combustor to produce vitiated air at high temperature and high-oxygen concentration. The reaction behavior of coal during combustion and/or gasification are elucidated by means of sampling and analyzing both reacting particles and reaction gases as well as optical measurement of the instantaneous particle temperature. Evolution rate of the volatile matter for various types of coal at high temperature is obtained from the Arrhenius plots. As a result, the volatile matter is rapidly evolved as soon as coal particles are introduced into the furnace since temperature of the vitiated air increases sufficiently. Result shows that the evolution rate of volatile matter does not depend on coal types. Activation energy and frequency factor of the evolution rate of volatile matter for various types of coal remain almost constant in the particle temperature range of 2 200 to 2 700 K, even when other experimental conditions were varied. In the char combustion region, char structure was found to affect the reaction rate of fixed carbon. It is observed that coal, which forms a network-type of char, indicated reaction rate of fixed carbon which did not always increase even when the vitiated air temperature was high enough. For a balloon-type char, on the other hand, the reaction rate of fixed carbon decreased with an increase of the vitiated air temperature.

Precise and quantitative behaviors on ash deposition phenomena in high-temperature coal gasification were studied, using a horizontal pulverized coal gasifier with a pre-combustor. The deposition experiment was carried out by inserting a water-cooled tube into the gasifier. The deposition phenomena were quantitatively and visually discussed by analyzing ash particles in the raw coal, the reacting particles and the deposition layer by means of CCSEM. As a result, particle diameter and chemical composition of ash particles rapidly change in the initial stage. The included mineral particles tend to agglomerate inside a coal particle during volatile matter combustion.

K-2233 Co-combustion Characteristics of Coal with Biomass

Morishita Keiju, Naruse Ichiro

The proceedings of the JSME annual meeting Vol. 1 ( 0 ) page： 603 - 604 2001

Publishing type：Research paper (scientific journal) Publisher：The Japan Society of Mechanical Engineers

In order to utilize low-grade coals efficiently and cleanly, co-combustion of coal with biomass was proposed since the biomass had the function to enhance the overall reaction characteristics. In this study, co-combustion of coal with biomass was tested by an electrically heated drop tube furnace to elucidate effect of the biomass on the combustion characteristics of coal. As a result, the biomass can enhance ignition of the low-grade coal during the co-combustion. Formation of NO under the co-combustion condition tended to relatively increase.

K-2223 Combustion and De-chlorination Characteristics of Refuse Derived Fuels

Fundamentals on de-chlorination characteristics with Refuse Derived Fuels (RDF), which had been developed to utilize as source for thermal energy, were studied by using both the practical RDF and the simulated RDF. For the simulated RDF polyvinyl chloride (PVC) or NaCl was added as a chlorine source. In the experiment single pellet of RDF was burned in an electrically heated batch furnace. The de-chlorination efficiency was calculated by means of analysis of Cl in the residue after combustion. The efficiency obtained was compared with that obtained by chemical equilibrium calculation. As a result, HCl is almost emitted during the volatile matter combustion. The de-chlorination characteristics for PVC addition differ from that for NaCl addition. For the RDF adding the de-chlorination reaction depends on the furnace temperature, and the optimum temperature is about 923 K. The phenomena are caused by the following reasons. At low temperature the de-chlorination rate is slower than the evolution rate of HCl gas. At high temperature, on the other hand, CaCl_2, which is produced by the de-chlorination reaction, is decomposed during the char combustion. For the NaCl addition, Ca compound does not absorb Cl in NaCl. According to chemical equilibrium calculation, NaCl is evaporated as a form of NaCl and Na_2Cl_2 vapors. HCl is not produced either.
