Mar 30, 2021The morphology of FBC fly ash grains is different from that of fly ashes obtained in pulverized fuel-fired boilers. Many papers, including [1,3,4,5], demonstrate that FBC fly ashes contain more hydrated aluminosilicate substance, anhydrite, calcium oxide and quartz compared to fly ashes coming from combustion in pulverized fuel-fired boilers.. Particles of siliceous fly ash have a spherical ...

Nov 14, 2021Cofiring coal with methane gas (or LNG) has the following benefits. (4) First, emissions can be reduced in proportion to the amount of coal replaced with methane gas. In particular, NO x emissions can be potentially reduced beyond the gas cofiring rate by the reburning mechanism. Second, the method facilitates flexibility in fuel use.
