This work investigates heat transfer characteristics in a bubbling fluidized bed with a
submerged superheater tube bundles under conditions of an integrated fluidized bed heat …

A U-type reduction chamber (URC) is developed as the key component of the novel iron ore
suspension roaster. It consists of a fluidization chamber (FC) and a supply chamber (SC) …

A loop seal is used to control a solid circulation rate and loop seal aeration ratios at the
supply and recycle chambers are another factor that affects its efficiency and circulating …

The external heat exchanger (EHE) plays an essential role in the adequate control of the
heat balance in large-scale oxy-fuel circulating fluidized bed (CFB) boilers. However, the …

On the basis of measurements on the fluidized bed heat exchanger (FBHE) of a 300 MW
lean-coal-fired circulating fluidized bed (CFB) boiler under different thermal loads and …

A pressure drop model for a U-typed reduction chamber was proposed from the pressure
balance law to predict pressure in the bottom of fluidization chamber under its stable …

This research aimed to investigate the effect of modified aeration scheme of U-type loop seal
on flow behaviors of solid particles that has influence on solid circulation rate. Two types of …

Fly ash is a by-product of coal-fired power plants, whose production is huge. As the coal
resources are in short supply in recent years, most circulating fluidized bed (CFB) boilers in …

A mathematical model for predicting the flow behavior through a conventional U type loop-
seal was developed by considering the loop-seal as a lumped system. The change rate of …

A loop-seal having a horizontal immersed tube bundle in the recycle chamber with aeration
at the bottom of the supply and return chambers or a conventional loop seal with heat …
