Uncontrolled NO x, emissions from pulverized coal technologies typically ranges from 0.3 to 0.7 lbs/10 6 Btu, but NO x, emissions from fluidized bed technologies is several times less, typically 0.12-0.2 lbs/10 6 Btu. However, even more stringent emissions regulations are being encountered, typically on the order of 0.10 lbs/10 6 Btu.
Approximately 50 million ton of municipal waste is generated in Pakistan per annum and most of this waste does not reach final deposit sites. In this research, Silvia gas technology for municipal solid waste (MSW) steam gasification is studied to produce high energy density product gas. A detailed simulation model is developed with the help of Aspen Plus®. Catalyst …
During wastewater treatment, biofilm‐coated sand particles stratified in a fluidized bed bioreactor (FBB); particles coated by thicker biofilm segregated toward the top of the bed. Stratification was so well developed that at least two co‐existing regions of significantly different mean biofilm thickness were visually distinct within the operating FBB. The observed …

Coal gasification has been internationally accepted as one of the most viable and effective clean coal technology for power generation. Presently, the coal being produced in India is having high ash content and it is a major constraint for most of the commercial applications in process industries. The present paper deals with the variation of higher heating value (HHV) of …
The use of fluidized-bed for power generation is a rapidly growing technology in Asian countries. Recent development efforts in the worldwide energy picture have given much thought to ways of ...
Received 14 April 2008; Revised 17 Dec. 2008; Accepted 13 Jan. 2009 . Code Number: er09062. ABSTRACT. A solid – liquid –gas, multiphase reactor, called Inverse Fluidized Bed Bioreactor (IFBBR) was used in this study for the …
The performance of a magnetically stabilized fluidized bed is strongly affected by the properties of the air-fluidized dense medium, especially for the dry fine coal separation.

The absence of large-scale carbon nanotube synthesis technology (which we define as being of the order of 10 000 tonnes per plant per year) is limiting research and development activities across the sector. We contend that fluidized bed chemical vapour deposition (FBCVD) is the most promising technology for large-scale, low-cost, carbon nanotube synthesis. In this …

2 gas generation by anaerobic fluidized H granular bed bioreactors and the low solubility of H 2, the H 2 contained in the effluent would be partitioned into two components: solubilized 2 and non-solubilized HH 2. Non-solubilized H 2 would consist of H 2 molecules trapped in the liquid phase in the form of microscopic bubbles or as aggregated ...
High levels of nitrate are present in groundwater migrating from the former waste disposal ponds at the Y-12 National Security Complex in Oak Ridge, TN. A field-scale denitrifying fluidized bed reactor (FBR) was designed, constructed, and operated with ethanol as an electron donor for the removal of nitrate. After inoculation, biofilms developed on the granular activated …
Fluidized bed reactor-chemical vapor deposition (FBR-CVD) offers a cross between pack cementation and CVD processes.In addition, because of the excellent mixing and dispersion within the bed, efficient heat and mass exchange is ensured, giving uniform coatings on complex-shaped parts. 63–65 This allows uniform aluminide coatings to be produced on ferritic steels in …
15.4.2 Fluidized bed gasifiers. In fluidized bed gasifiers, the biomass is maintained in fluidized state by the gasifying agent flowing upward at an appropriate rate. Biomass is mixed with inert (or catalytic) bed material such as quartz sand, alumina, or dolomite in order to improve heat transfer.
A coupled system, an air dense medium fluidized bed (ADMFB), and a FGX separator were used by Xuliang et al. to increase the calorific value of the material by as much as 10.32 MJ/kg . Dong et al. performed a series of tests with the use of similar configuration, which allowed one to achieve an effective dry separation of coal in the 0–100 mm ...

Incineration, in spite of being a costly option, is widely used for the treatment and disposal of solid, liquid, and gaseous wastes. Use of fluidized beds paved the way for less polluting incinerators. Circulating fluidized bed systems can burn low-heat-content watery wastes without (or with minimum) auxiliary fuel.
