For the question of circulation wind emerged in the process of using long compression and short pumping ventilation dust removal system, a new model of air volume matching was proposed, and the empirical formula of the key process parameters such as axial and radial air volume, axial and radial air out distance were derived according to the relevant theories of air jet in the confined space. Then the 20106 return roadway of fully mechanized working face in Wang Jia Ling coal mine was selected to conduct field verification tests. The result showed that the new air volume catching model had good adaptability, and the key process parameters obtained by theoretical calculation and field test were basically identical. Under the condition of optimum technological parameters, the total dust and respiratory dust concentration of the driver’s place can be reduced 91.98% and 89.53% respectively.

Removal System

The deposition of lunar dust on the surface of solar panels and optical elements is one of the most important problems need to be solved in lunar exploration. This paper will propose an initiative lunar dust removal system based on the photovoltaic effect of PbLaZrTi (PLZT), which is activated by the ultraviolet light extracted from sun light at the lunar surface. When ultraviolet light with a wavelength near 365nm illuminates on polarized PLZT materials, high voltages of several kilovolt per centimeter can be generated between two electrodes of PLZT. When two electrodes of PLZT are connected to a lunar dust collector (LDC) and the ITO film of protected surface respectively, an electrostatic field forms between LDC and the protected surface. Coulomb forces over particles will overcome gravitational force and surface forces, so the particles can be absorbed to LDC and removed by LDC finally. Based on the equivalent electrical model, mathematical model of electrostatic force is derived when the lunar removal electric field is acted either by single piece PLZT or by multi-pieces PLZT which are connected in parallel. Experimental platform is set up to prove the feasibility of this lunar dust removal system. In order to improve the removal efficiency, a novel configuration design of LDC based on multi-PLZT patched is proposed and its removal efficiency is evaluated by experiments.

Solar Turbines Incorporated, a subsidiary of Caterpillar Inc., is currently developing under DOE sponsorship a coal-fueled version of its industrial Centaur Model H gas turbine for cogeneration applications. A critical sub-system component is the coal-fueled combustor island consisting of a Two-Stage Slagging Combustor (TSSC) with an integrated Particulate Rejection Impact Separator (PRIS). Earlier development of the TSSC consisted of basic feasibility demonstrations and emissions evaluations and has been reported previously together with preliminary system design and assessment data. This paper reports on the continued bench-scale development of the combustor island with the objective of developing a data base suitable for use in scaling-up the design by an order of magnitude to a rating consistent with application to the 3.8 MW Centaur Model H gas turbine. Development activities have included analytical and flow visualization modeling; sorbent injection tests for control of sulfur oxides; and baseline evaluations of a continuous slag removal system. A preliminary engine-size combustor island design is also presented.
