Reducing Ash Agglomeration in JEA’s CFB Boilers

In CFB boilers, the agglomeration potential is naturally high due to the presence of a large quantity of ash circulating in the hot loop (see the sidebar for a description of NGS’s CFB boilers

Agglomeration Detection in Circulating Fluidized Bed

2018-12-5 · The schematic illustrated in Figure1is that of a CFB. Its a type of boiler that uses sand as the fluidizing me-dian, where a degree of solid reflux is achieved allow-ing for a more uniform temperature throughout the boiler. Major advantages include stable combustion at low tem-peratures (750-900 C), uniform temperature distribution,

2010-5-4 · Agglomeration of a fluidised bed is the most typical problem and a very aggravating one since it can appear suddenly (Brus et al., 2005; Zevenhoven–Onderwater et al., 2001). In bed agglomeration the ash in the fluidised bed reaches a state where individual ash particles start to stick to each other and sand particles. The lumps formed do not

The size of a CFB increases more slowly than a BFB when the steam capacity is scaled up (see Figure 9). A modern biomass CFB boiler can be operated with NO x emissions of less than 150 mg Nm −3, less than 200 mg SO x and CO Nm −3, and less than 20 mg dust Nm −3.
