fbc desulfurization process using coal with low sulfur . - CiteSeerX

molar ratio, desulfurization efficiency decreased in relation to the increased Ca/S. Thus, it must be highlighted that the efficiency of desulfurization is strongly dependent on the initial SO2 concentration in the bed (Fig. 1). The addition of line at Ca/S = 1 promoted a reduction of the SO2 emission from 900 ppm to ~450.

PROCESS DESCRIPTION

(B) MATHEMATICAL MODEL OF LINE DISSOLUTION. As CaCO3 dissolves from the line contactor media, particle size, bed depth, bed porosity, flow velocity and pressure drop change with time. It is important to make design choices for these variables since they affect the dissolution rate and recharge.

The influence of air staging in the reduction of SO2 by line in a .

A recent technique for reducing NOx emissions combines staged combustion with ammonia injection. However, concern has arisen about the effect of low primary air:coal ratio (PACR), and hence low bed oxygen levels, on the rate of reaction between calcined line and SO2. This paper reports on the significance of.

Low temperature production of wollastonite from line and .

The ratios of line/sand used were 1:1, 2:1 and 3:1 with various firing temperatures, namely 1100, 1200, 1300, 1400 and 1450 °C. The raw materials and fired products were characterised for mineral phases, chemical composition of content such as CaO, SiO2 and loss on ignition (LOI), density and microstructure.

What happens to concrete which is mixed using coarse aggregate composed of a high percentage of line dust? . strength can be considerably reduced, and the dust material increases the water requirement of the concrete so that the water-cement ratio is increased, thereby increasing shrinkage and.

Portland Line Cement Part I - Preparation of Cements†1

line replacement ratio of 5% is faster than samples prepared with only Portland cement. Similar results are also reported from the view point of total heat of hydration. However, heat of hydration tends to decrease at higher replacement ratios due to reduction in total cement content [6]. Until a definite ratio, finely ground.
