Fuels and Combustion Pick out the wrong statement. None of these Pulverised fuel can be completely burnt with less percentage of excess air compared to lump coal Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing Low grade coal can be used, but generally high volatile matter coals are more suitable for making pulverised fuel None of these Pulverised fuel can be completely burnt with less percentage of excess air compared to lump coal Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing Low grade coal can be used, but generally high volatile matter coals are more suitable for making pulverised fuel ANSWER DOWNLOAD EXAMIANS APP
