Sentence examples for fast bed from inspiring English sources

Circulating fluidized bed combustion boiler (CFBC) is the system in which steam is produced after burning of fossil fuels in furnace which operates under special hydrodynamic condition known as Fast bed.

The configuration comprises a bottom turbulent fluidized bed, wherein the oxidative coupling reaction is conducted, followed by a reduced-diameter top fast bed for catalyst entrainment and hydrocarbon cracking.

Industrial application showed that by changing the amount of bed inventory, CFB boilers could operate at a re-constructed fast bed state, not only saving ~30% power of the draft fans, but also further reducing the erosion on water walls and improving combustion efficiency.

The model includes mass balances of oxygen and carbon, energy balances, as well as sub-models for the gas-solid flow structure, combustion, and heat transfer from the bed to both the refractory walls and to a waterwall located in the fast bed section.

The apparatus combines a fast-bed riser with a conical dipleg into a circulating fluidized bed (CFB) loop.

The micro-scale discrete ultra-fine particles gather together into meso-scale agglomerates on account of inter-particle forces, in both the fast-bed riser and the conical dipleg.

The fast-bed riser, because of its high and relatively uniform gas velocity, serves to adjust the size, especially the size distribution of the agglomerates, that is, further capture of discrete micro-scale discrete particles for the smaller agglomerates to make them larger, and attrition of over-size agglomerates to make them smaller.

In particular, in the latter, the fine particles are sufficiently entrapped because of reduced gas velocity in the top region, into the top-to-bottom and center-to-periphery mixing currents of the solids, to form agglomerates before being recycled to the bottom of the fast-bed riser.

Based on this theory and method, the decomposition of ozone at ambient temperature is calculated in a fast fluidized bed with average and local bed structure parameters and the axial and radial dimensionless concentrations of ozone and averaged mass transfer coefficients are compared to experimental data from the literature.

In the process developed model, a fast fluidized bed model and a bubbling fluidized bed model are used to respectively represent the oxidation reactor and the reduction reactor, while fluidized bed hydrodynamics and oxygen carrier redox reaction kinetics are considered to grasp the unique characteristics of CLAS process.

Modeling and simulation of circulating fast fluidized bed reactors (CFFBR) and circulating fast fluidized bed membrane reactors (CFFBMR) for hydrogen production by oxidative reforming of methane are presented in this paper.
