where, qF is the filter quality factor, P is the particle
penetration,and Δp is the pressure drop across the filter
media. In terms of quality factor,the ceramic filters sintered at
1350 C and 1400 C achieved better filtration performance
than other filters due to their high collection efficiency and low
pressure drop as shown in the Fig. 10. However,mechanical
strength must be considered for thermal resistance and filter
cleaning durability in hot gas filtration.The ceramic filters
sintered at 1350 C and 1400 C showed lower mechanical
strength than other filters,which might result in a reduced filter
life time.Therefore,both mechanical strength and filter quality
factor should be considered to choose a better ceramic filter.
