  • Energy and Exergy Balance in the Process of Pulverized ...

    A theoretical model of exergy balance, based on availability transfer and flow availability, in the process of pulverized coal combustion in a tubular air-coal combustor has been developed to evaluate the total thermodynamic irreversibility and second law efficiency of the process at various operating conditions.

  • System for the safe handling of pulverized coal (Patent ...

    Abstract. A system for the safe handling of pulverized coal includes conventional coal pulverizing and drying equipment, with cyclones and bag filters added, the latter serving to separate the fine coal from the conveying gas (usually air); and explosion suppression and fire suppression systems, both of which include conventional components.

    pulverized coal occurred in the brick-kiln in 1831, and fluidized-beds were invented in 1931. Nowadays, direct coal combustion is extensively utilized for industrial and domestic purposes because of the large-scale reserves and low cost of coal. Most of the world's ...

    and coal and ash particle concentrations present in practical units. The full-scale pulverized-coal boiler (Ishikawa-jima-Harima Heavy Industries [IHI]-tested facility) is an industrial boiler with a steam rating of 580 tonnes/h. This facility, operated at 510 tonnes/h of steam (coal feed rate of 63.5 tonnes/h), is equipped with a catalytic DeNO
