In order to study the migration and transformation of SO 3 from circulating fluidized bed boiler (CFB) in air preheater flue gas treatment facilities, 10 boilers with installed capacities between 150 MW 330 were measured by controlled condensation method. Ten ranging using It is showed that removal rate was affected exit temperature, which ranged 6.7 % 36.5 %, rotary higher than tubular preheat...

nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. in this research, the powder was characterized by x-ray diffraction (xrd) and transition electron microscopy (tem) for determination of phase structure, morphology and particle size. furthermore, the specific surface area of the powder was ...

background: in the present study, histopathological effects of chronic exposure to sodium arsenate in drinkable water were studied on a quantity of organs of rat. methods: rats were divided into two groups, group i served as control group, were main-tained on deionized drinkable water for 2 months, and group ii the study group were given 60 g/ml of sodium arsenate in deionized drinkable water ...

Developments of large scale and high-purity generation technique of single-walled carbon nanotubes (SWNTs) [1] are desired for the practical applications of the fascinating new material. In addition to previously known laser-furnace [2] and arc-discharge [3] techniques, recently, the catalytic chemical vapor deposition (CCVD) method [4] has been developed for the possible larger amount producti...

In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...

The analysis of scientific publications containing information about the equipment and methods modeling process pulverized fuel combustion is carried out. basic requirements for ensuring reliability research results are formulated. conclusion made possibility expediency using installations type "vertical tubular furnace" to find ways increase completeness coal in blast furnaces raceway. Emphasi...

The combustion process of TiO2- 2Mg- C and 3TiO2-4Al-3C systems in a tubular furnace was investigated. TiC has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of TiO2, Mg and charcoal as starting materials in the presence and absence of NaCl. The effects of temperature, pressure, and the stoichiometry ratio in the reactio...
