Fuels and Combustion Low temperature carbonisation Is meant for the production of 'metallurgical coke' Is mainly for producing the smokeless domestic coke Produces less quantity of tar than high temperature carbonisation Produces higher quantity of gas than high temperature carbonisation Is meant for the production of 'metallurgical coke' Is mainly for producing the smokeless domestic coke Produces less quantity of tar than high temperature carbonisation Produces higher quantity of gas than high temperature carbonisation ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Fuel gases containing hydrocarbons (ie.g. coke oven gas) are not preheated before burning, mainly because It reduces its flame temperature tremendously It reduces its calorific value tremendously There are chances of explosion during preheating The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its flame temperature tremendously It reduces its calorific value tremendously There are chances of explosion during preheating The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Preheating of combustion air is done to Reduce its requirement for effecting the complete combustion Increase the adiabatic flame temperature Complete the combustion of fuel Increase the calorific value of the fuel Reduce its requirement for effecting the complete combustion Increase the adiabatic flame temperature Complete the combustion of fuel Increase the calorific value of the fuel ANSWER DOWNLOAD EXAMIANS APP
