With sulphur capture additive, the contents of As, Se, Sb, Zn in the fine particles of CFB ash decrease, and the contents of As, Se, Li, Be, Mo, Cr, Co, Ni in the ash from chimney after dust remover and the contents of Cu, Zn, Cr, Pb, Co, Ni, F, and Se in the spraying water from chimney decrease.
This article elaborates the principle and design of the nwe-type boiling dust remover which effectively get rid the smoke and dust from fluidized boiler.
Compared with the current flue gas purification techniques using pulse corona discharge, the new technique dose not need the special dust remover, and reduces investment and occupying area while ensuing the economic value of the byproducts.
Several dust removers with doses of 100, 200, 400, 800, 1600, 3200 and 6400ppm weresprayed on wheat respectively for screening dust removers. Then, the unit weight, staticangle, germinating ability, germination, moisture content, foreign matter, fatty acid value ofgrain and repellency for insect and their difference were determined and compared. The resultshowed that phosphatide solution was the satisfactory dust remover.

Through analysing the technological processes, its equipments and the amount of dust contained in the working area of a jute mill, the author suggests that in order to decrease the concentration of dust in air, the technological processes must be innovated, the working operations shortened, the continuation of production process increased, the equipments improved, and dust remover for individual equipments installed. For the equipments and the working places where dust remover is not suitable to install, dust trap or dust sucker may be used. The author also investigates and analyses the designing parameters and the form of the dust trap and dust sucker. Finally, the author deals with the characteristics of the dust and the performance of the purifying equipments.
This paper described the sand pre-treatment and batch preparing process consisting of a sand washing line, a batch preparing line, a pulse sack dust remover and mechanical elevators etc. The operation practice showed that this production line reduced the labour intensity, controlled the siliceous dust under 2 mg/m~3, improved the glass batch so that the great benefit has been derived.
