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