Fuels and Combustion A coal gasifier opearating at 20 atm. (e.g. Lugri gasifier) as compared to one operating at atmospheric pressure (e.g. Kopper-Totzek or Winkler gasifier) will produce a gas having Lower carbon dioxide content None of these Higher methane content and thus higher calorific value Higher carbon monoxide content Lower carbon dioxide content None of these Higher methane content and thus higher calorific value Higher carbon monoxide content ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion The main advantage of forced draft over natural draft is that Smaller height chimney can be used Combustion of fuel is complete All of these Furnace control is easier Smaller height chimney can be used Combustion of fuel is complete All of these Furnace control is easier ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Fuel gases containing hydrocarbons (ie.g. coke oven gas) are not preheated before burning, mainly because There are chances of explosion during preheating It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its calorific value tremendously There are chances of explosion during preheating It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its calorific value tremendously ANSWER DOWNLOAD EXAMIANS APP
