Fuels and Combustion Coke compared to the coal from which it has been made, contains All of these Less volatile matter More carbon Greater percentage of ash All of these Less volatile matter More carbon Greater percentage of ash ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion A coal having higher volatile matter content will necessarily have lower Ignition temperature Calorific value Ash fusion temperature Caking index Ignition temperature Calorific value Ash fusion temperature Caking index ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Gross and net calorific value of a fuel will be the same Ifits carbon content is very low Under no circumstances If its ash content is zero If its hydrogen/hydrogen compound content is zero Ifits carbon content is very low Under no circumstances If its ash content is zero If its hydrogen/hydrogen compound content is zero ANSWER DOWNLOAD EXAMIANS APP

Fuels and Combustion Pick out the wrong statement. 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 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 ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Stack heat losses can be minimised by Using low c.v. fuels Controlling the excess air Maintaining proper draft in the furnace Oxygen enrichment of combustion air Using low c.v. fuels Controlling the excess air Maintaining proper draft in the furnace Oxygen enrichment of combustion air ANSWER DOWNLOAD EXAMIANS APP
