Book Description
In the spring of 1989, two separate test series were simultaneously conducted at the US Department of Energy's (DOE's) Morgantown Energy Technology Center (METC) to examine applied and fundamental behavior of dust cake filtration under high temperature and high pressure (HTHP) conditions. The purpose was to provide information on dust-cake filtration properties to gas stream cleanup researchers associated with the Tidd 70 megawatt (MW) pressurized fluidized-bed combustor (PFBC). The two test facilities included (1) a high-pressure natural-gas combustor with injected particulate, which was fed to two full-size candle filters; and (2) an atmospheric fluidized-bed combustor (AFBC) with coal and limestone sorbent to generate a particulate-laden combustion exhaust gas, which was sent to a single full-size candle filter and a small-scale disc filter. Several major conclusions from these studies are noted below. On average reducing the mean particulate size by 33% and the associated loading carried in the filtrate will increase the dust cake specific flow resistance (K2) by 498%. High-temperature and high-pressure filtration can be successfully performed with ceramic candle filters at moderate filtration face velocities and reasonable system pressure drops. Off-line filter cleaning can produce a filter system with a higher apparent permeability than that produced from on-line filter cleaning at the same face velocity. 19 refs., 89 figs., 13 tabs.

Dust Cake Behavior in Filters with High Surface Area to Volume Ratios

Languages : en
Pages : 8
Book Description
High-temperature particulate control devices are an integral part of advanced coal-fired power systems. By efficiently removing minute particles from high-temperature gas streams, environmentally clean and efficient power systems can be realized. In recent years, economic incentives have prompted developers of high-temperature and high-pressure (HTHP) particulate filtration systems to pursue filter element designs with more filter surface area for a given volume. Although higher surface-to-volume (SV) ratio filter designs are driven by economic incentives, physical constraints and the fundamental behavior of dust cake formation and removal will limit the maximum SV ratio. In an attempt to improve the understanding of dust cake behavior in a well controlled environment, a two-dimensional cold flow filter module is being tested. This filter module can be used to investigate dust cake formation, removal, and re-entrainment over a range of operating conditions. Preliminary results suggest that the cohesive strength of the particulate media has a strong influence on how the dust cake is removed during reverse pulse cleaning. Furthermore, the properties of the particulate media play an important role in forming non-uniform dust cakes. In the following paragraphs, the experimental apparatus, preliminary results, and future plans will be discussed.
