Fuels and Combustion Prime coking coal is always blended with medium or non- coking coal before ear-bonisation To check against its excessive swelling during heating, which may exert high pressure and damage coke oven walls Because, it alone produces unreactive coke Neither A nor B Both A & B To check against its excessive swelling during heating, which may exert high pressure and damage coke oven walls Because, it alone produces unreactive coke Neither A nor B Both A & B ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Pick out the wrong statement. Pulverised fuel can be completely burnt with less percentage of excess air compared to lump coal Low grade coal can be used, but generally high volatile matter coals are more suitable for making pulverised fuel None of these Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing Pulverised fuel can be completely burnt with less percentage of excess air compared to lump coal Low grade coal can be used, but generally high volatile matter coals are more suitable for making pulverised fuel None of these Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing ANSWER DOWNLOAD EXAMIANS APP
