Fuels and Combustion Pulverised coal used in boiler firing need not have High fusion point of its ash Less moisture content Lower ash content High bulk density High fusion point of its ash Less moisture content Lower ash content High bulk density ANSWER DOWNLOAD EXAMIANS APP
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 Higher methane content and thus higher calorific value Higher carbon monoxide content None of these Lower carbon dioxide content Higher methane content and thus higher calorific value Higher carbon monoxide content None of these Lower carbon dioxide content ANSWER DOWNLOAD EXAMIANS APP
