The Performance of a Loop Seal in a CFB Boiler | …

In order to increase the knowledge on the flow pattern and the heat transfer distribution to the tubes within a loop seal, measurements were performed in the loop seal of a 30 MW CFB boiler as well as in a 1 ∕ 3 scaled-down seal operated according to simplified scaling laws. The scale model measurements show that the solids recirculation flux

Studies on the operation of loop-seal in circulating

Downloadable (with restrictions)! Loop-seal, considered heart of a circulating fluidized bed (CFB), returns solids captured by cyclone to the base of the riser while preventing direct flow of gas from high pressure riser to the low-pressure cyclone. This non-mechanical valve is used in thousands of CFB systems yet only a limited information is available on its working.
