Sentence examples for fluidized from inspiring English sources

In this gasifier, coal (usually crushed to less than 12 millimetres) is fed by a screw feeder and is fluidized by the gasifying medium (steam-air or steam-oxygen, depending on the declared calorific value of the product gas) entering through a grate at the bottom.

Methods of contacting the solid feed and the gaseous reactants in a gasifier are of four main types: fixed bed, fluidized bed, entrained flow, and molten bath.

Powdered metal is fluidized by argon in a pressure vessel and injected by a refractory-lined lance deep into the liquid steel.

Current research on alternative means for combustion (e.g., fluidized bed combustion, magnetohydrodynamics, and low nitrogen dioxide burners) is expected to provide efficient and environmentally attractive methods for extracting energy from coal.

This is especially true if the blast cloud is heavily laden with fragmental debris and becomes dense and fluidized.

Another mode of film formation closely related to water-based coalescence is the melting and fusing of solid paint particles such as occurs in what is known as "powder coating," a process in which an object is coated by a spray or fluidized bed of pigmented polymer particles and the particles are fused by heating to form a continuous film.

This is accompanied by sharp closure of the shell valves, forcing water out of the mantle cavity into the burrow, helping to fluidize the sediment, and making movement through it more efficient.

Subsequent treatment of powdered UO2 with gaseous hydrogen fluoride (HF) at 550° C (1,025° F) produces uranium tetrafluoride (UF4) and water vapour, as in the following reaction: This hydrofluorination process is usually performed in a fluidized-bed reactor.

The product-sized agglomerates of aluminum hydroxide crystals are filtered, washed to remove entrained caustic or solution, and calcined in rotary kilns or stationary fluidized-bed flash calciners at temperatures in excess of 960° C (1,750° F).

Both of the main extraction methods for the production of zinc, electrolysis and smelting, require the prior removal of sulfur in a highly exothermic oxidation reaction: For the electrolytic production of zinc, the roasting of concentrates is achieved in fluidized-bed roasters, in which finely divided and heated particles of concentrate are suspended in a rising stream of air.

The Winkler gasifier is a fluidized-bed gasification system that operates at atmospheric pressure.
