Engineering Thermodynamics Mond gas is obtained by Partial combustion of coal, coke, anthracite coal or charcoal in a mixed air steam blast Carbonisation of bituminous coal Passing air and a large amount of steam over waste coal at about 650°C Passing steam over incandescent coke Partial combustion of coal, coke, anthracite coal or charcoal in a mixed air steam blast Carbonisation of bituminous coal Passing air and a large amount of steam over waste coal at about 650°C Passing steam over incandescent coke ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The distillation carried out in such a way that the liquid with the lowest boiling point is first evaporated and re-condensed, then the liquid with the next higher boiling point is then evaporated and re-condensed, and so on until all the available liquid fuels are separately recovered in the sequence of their boiling points. Such a process is called Full distillation Cracking Carbonisation Fractional distillation Full distillation Cracking Carbonisation Fractional distillation ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics Coke is produced By heating wood with a limited supply of air to a temperature not less than 280°C When coal is strongly heated continuously for 42 to 48 hours in the absence of air in a closed vessel When coal is first dried and then crushed to a fine powder by pulverizing machine From the finely ground coal by moulding under pressure with or without a binding material By heating wood with a limited supply of air to a temperature not less than 280°C When coal is strongly heated continuously for 42 to 48 hours in the absence of air in a closed vessel When coal is first dried and then crushed to a fine powder by pulverizing machine From the finely ground coal by moulding under pressure with or without a binding material ANSWER DOWNLOAD EXAMIANS APP
