“…The filters produced in this work present permeability values that match the group of gel cast foams, fibrous, and granular filters used for aerosol filtration (especially for hot cleaning). Cell size and permeability of the developed cellular ceramics point them as potential candidates for their use as aerosol filters ( K 1 in the range of 10 −12 m 2 ) 14,22,23 as well as temperature control membranes in ATR ( K 1 in the range of 10 −12 –10 −13 m 2 ) 15 .…”

A new processing route for high‐performance graded ceramic filters is presented. The direct foaming process is based on the transition of a surfactant‐stabilized alkane dispersion in a stabilized aqueous ceramic powder suspension into mechanically stable ceramic foams with porosities up to 90%. The cell size distribution and, consequently, the permeability of the filters could be efficiently adjusted by the control of the high alkane phase‐emulsified suspension (HAPES) microstructure during emulsification. Furthermore, open porous graded structures are produced by combining HAPES layers with different droplet sizes. The tailored microstructural features, providing controlled permeabilities as well as high compressive strength of the cellular ceramics are of special interest for applications where fluid transport through ceramic microstructures is required. These include filters, in particular for aerosol filtration, temperature control membranes in autothermal reforming, catalytic supports including supports for batteries as well as matrices for immobilized microorganisms.

“…Stationary sources, such as coal-fired power plants, emit a mixture of particles of various sizes. Controlling particle emissions from coal-fired power plants is an established technology that is continuously being enhanced by the introduction of new methods [9]. The major technologies used to control particle emissions from pulverized coal-fired power plants are mostly mechanical collectors.…”

Particulate matter emissions of filterable particulate matter (FPM), condensible PM (CPM), PM10, and PM2.5 at FGD inlet and stack in a coal-fired power plant were measured by EPA method 201A and method 202. The results indicated that emissions of total particulate matter (TPM) are 40.99mg/m 3 and 120.58mg/m 3 , and the filterable PMs are the highest emissions at both sampling locations which accounted for 76.3% and 75.4% of TPM, the PM10 are 14.73mg/m 3 and 88.23 mg/m 3 , the PM2.5 are 3.17mg/m 3 and 52.15mg/m 3 at FGD inlet and stack, respectively. The concentration of PMs in flue gas increases significantly after the flue gas passing through the FGD unit. The increase values of PM10/FPM and PM2.5/FPM ratios are 106% and 266%, respectively, but the CPM/TPM ratio is almost at the same level (23.7~24.6mg/m 3 ) after the flue gas passing through the FGD. The test indicated that FGD operation has a significant effect on particulate matters emission due to releasing finer particles and part volatile metals in FGD slurry. Some measures should be taken to control PM emissions for a utility boiler equipped with FGD unit.

The generation of energy for thermoelectric has the benefit of not relying on environmental situations, as in the case of hydropower that can be influenced by the effects of weathering on the high or low level of its water reservoirs. However, the thermoelectric plants can bring harm to the environment by the emission of particulate material into the atmosphere. Filters of various principles can be used for containment of those fly ashes, as the cyclone filter. Given the relatively low costs involved this is widely used in a industrial scale and, for having a greater scope for gains in efficiency, will be addressed during this exposed. Is this article, it’s contemplated the study of the influence of the system’s variables, such as flow velocity of the gas inlet and the diameter of the particles suspended therein. It must be said that this study aims to technical study the filter, not normally considered the economic feasibility of possible changes and implementations; as such factors may serve as a disincentive to finding new methods and technology, which, since then, must be evaluated economically.
