Fuels and Combustion Correct viscosity of furnace oil at the burner tip for proper atomisation is about 25 centistokes. To reduce the viscosity of high viscosity furnace oil (250 centistokes) to the correct atomisation viscosity (i.e. 25 cst), it should be preheated to about____°C. 85 105 70 145 85 105 70 145 ANSWER DOWNLOAD EXAMIANS APP
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 Low grade coal can be used, but generally high volatile matter coals are more suitable for making pulverised fuel Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing None of these 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 Regulation of furnace temperature and atmosphere (oxidising or reducing) is easily possible with pulverised fuel firing ANSWER DOWNLOAD EXAMIANS APP
