Adsorption properties of CFBC ash–cement -

Circulating fluidized bed combustion (CFBC) ash can be potentially used as supplementary cementitious materials for concrete production due to its desirable pozzolanic activity. The adsorption properties of CFBC ash–cement pastes were studied, and ordinary pulverized coal combustion (PCC) fly ash–cement pastes were used as control.

Appearance of Trace Elements in Co-Firing Fuel

With this method fuels are leached in three steps, i.e. leached with water, ammonium acetate and hydro chloric acid, respectively. Both solubility in different leaching agents of main ash forming matter and the trace elements Cd, Tl, Hg, Sb, As, Pb, Cr, Co, Cu, Mn, Ni, V and Zn were studied.

Emissions of Inorganic Trace Pollutants from Coal

2018-11-5 · Coal-fired power plants are a major source of emissions for a number of air pollutants including SO2, NOx, particulate matter (PM), HCl, HF, Hg, and so on. Hazardous air pollutants such as As, Be, Cd, Cr, Pb, Mn, Ni, Se, and other metals are integral components of fine PM that are also emitted directly from coal-fired power plants. The potential problem of coal-fired power plants associated to

Agglomeration and Fouling in Three Industrial

2016-11-18 · Petroleum coke is quickly becoming the fuel of choice for many FBC boiler operators, due to its low cost, high availability and high heating value. However, these inherent benefits come with a price, as the high sulfur content of coke requires limestone use as a sorbent for sulfur capture. In some cases, operational problems associated with limestone use have arisen.

A review of some operation and maintenance issues

Bed materials commonly used are retrieved bed solids from the previous boiler run, limestone and silica sand. Selection of start-up bed material plays an important role in quick and trouble free start-up of the boiler. For start up the bed material should be within the specified size spectrum and should not be …

Agglomeration in Stripper Ash Coolers and -

Abstract. The bottom ash of circulating fluidized bed (CFB) boiler contains large amounts of physical heat. When low quality coals are used in these types of boilers, the ash content is normally more than 40 % and the physical heat loss is approximately 3 % if the bottom ash is discharged without cooling.
