DESIGN OF A FAST INTERNAL CIRCULATING FLUIDIZED BED GASIFIER

cussed in a detailed study by Kaiser et al. [2]. Some studies of circulating fluidized bed loop predictions can be found in the literature. Breault and Mathur [3] analysed a high-velocity-loop fluidized bed. Bai et al. [4] investigated a dual fluidized bed system with two risers, down-com-ers and two valves.

Circulating fluidized bed gasifier for biomass

This paper introduces a circulating fluidized bed gasifier (CFBG) with a diameter of 410 mm, a height of 4000 mm and a load of 250 kg/h for wood powders. The CFBG system, including gasifier, feeding and circulating are all operated pneumatically. The design of the CFBG is presented. The main parameters which affect the gasification processes

Circulating fluidized bed gasifier - Patent JP-5417753-B2

Jul 11, 2008 · This web page summarizes information in PubChem about patent JP-5417753-B2. This includes chemicals mentioned, as reported by PubChem contributors, as well as other content, such as title, abstract, and International Patent Classification (IPC) codes.

Hydrodynamic Study of a Circulating Fluidized Bed at High

Besides, studies carried out by Bull (2008) and Detournay (2011) focused on the hydrodynamic of a circulating fluidized bed biomass gasifier at ambient temperature using olivine (dp = 250 μm) and sand particles (dp = 316 μm) as media. Results showed that gas velocity in the riser (combustor) and total inventory are the main parameters which

5.2.3. Fluidized Bed Gasifiers | netl.doe.gov

Fluidized-bed gasifiers suspend feedstock particles in an oxygen-rich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ back-mixing, and efficiently mix feed coal particles with coal particles already undergoing gasification. To sustain fluidization, or suspension of coal particles within the gasifier, coal of

Circulating Fluidized Bed Gasification - Biofuels Academy

The main difference between fluidized bed systems and circulating fluidized bed is the gas vortex created with the gasifier and the separator; this keeps solids in a long path of high temperature that will help to keep the process efficient. The fluidized nature inside of the reactor consists of the feed entering the reactor and the air/oxygen

Biomass gasification in a circulating fluidized bed

This paper presents the results from biomass gasification tests in a pilot-scale (6.5-m tall × 0.1-m diameter) air-blown circulating fluidized bed gasifier, and compares them with model predictions. The operating temperature was maintained in the range 700–850°C, while the sawdust feed rate varied from 16 to 45 kg/h.

Fluidized bed type reduction apparatus for iron ores and

The apparatus includes serially arranged a drying/preheating furnace with a first cyclone connected to it, a primary prereduction furnace with a second cyclone connected to it, a secondary high-gas-velocity reduction furnace for finally reducing only a coarse ore portion of the prereduced iron ores at a bubbling fluidized state while carrying
