Study on Powder Coke Combustion and Pollution Emission Characteristics of Fluidized Bed Boilers

A study on fluidized bed combustion characteristics of corncob in three different combustion modes.

This paper presents results obtained from corncob combustion in a pilot scale vortexing fluidized bed combustor (VFBC). Three combustion modes including direct combustion, staged combustion and flue gas recirculation (FGR) combustion were employed, and their combustion and pollutant emission characteristics were studied. In addition, the effects of combustion fraction and bed temperature on pol...

Studies on Ash Behavior during Co-Combustion Of Paper Sludge in Fluidized Bed Boilers

Cfd Analysis of Circulating Fluidized Bed Combustion

In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...

Experimental Study of Fluidized Bed Agglomeration of Acerola Powder

The aim of this work was to study the main effects of acerola powder on fluidized bed agglomeration. A 2 fractional factoring design was used to evaluate the main operating conditions (fluidizing air temperature, fluidizing air velocity, atomizing air flow and height of nozzle in the bed). The mechanical and physicochemical product changes were determined by analysis of particle diameter, moist...

Emission characteristics of co-combustion of sewage sludge with olive cake and lignite coal in a circulating fluidized bed.

In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800mm height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90, 15/85, 20/80) were tried. On-line concentrations of major compon...
