A novel suspension-floating-circulating fluidized

Feb 18, 2016 · A novel suspension-floating-circulating fluidized combustion technology is proposed for burning coal slurry fuel in traditional circulating fluidized bed boilers (CFBB). This technology can solve some existing problems in large-capacity CFBB burning coal slurry. The principles of the suspension-floating-circulating fluidized combustion technology were introduced in detail in this paper.

Experiment and Grey Relational Analysis of CWS Spheres

In order to study the combustion of coal water slurry (CWS) in fluidized bed boilers, artificial CWS droplet spheres were used for simulation of the spheres formed from CWS droplets which fall from the furnace top to the bed. The artificial spheres were introduced to a bench-scale fluidized bed furnace. Quartz sand was used as the bed material. The influence of the operation conditions (e.g
