Cfb boiler basic design, operation and maintenance

A high efficiency economical coal fired combined cycle power generation system and process is described. The system utilizes a circulating fluid bed ("CFB") coal devolatilizer which is fluidized with recycled coal volatiles. The devolatilizer is heated indirectly with hot bed material from a conventional CFB boiler burning the devolatilized coal (char).

The Role of Kaolin in Prevention of Bed Agglomeration

Kaolin addition to a 35 MW circulating fluidized-bed boiler, fired with forestry residues, was performed to study the effect on bottom and fly ash. Ash samples from a period of kaolin dosage were compared with ash samples without kaolin. The samples were analyzed for elemental composition, water solubility, and mineralogical composition.

Sep 01, 2011 · Even if the kaolin additive is very fine-grained (D 50 = 0.8 μm) it does not lead to a peaking of 1–2 μm particle size fraction in the LPI samples. Instead the larger particle size fraction concentration increases. This may be due to the adherence of kaolin on the CFB bed sand particles, or kaolin platelets (re-)forming clusters.

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 10.5.2 Cyclones. A CFB boiler typically has one or more high temperature cyclone-type solid separators. These cyclones can be built separately, Fig. 10.8, or integrated into the furnace.Small-diameter cyclones would have a higher collection efficiency, but costs favor building fewer and bigger cyclones.

Kaolin, a chemically pure standard material with a Sauter mean diameter of 7.4 μm, was used as an additive to evaluate the effects on ash deposition when ZD coal was combusted in a CFB test system. Its chemical composition is given in Table 3. The kaolin was well mixed with ZD coal at the addition ratios of 3% and 6% based on mass.
