Fuels and Combustion Sometimes water is sprayed during coal charging in the coke oven, which helps in Reducing the cracking of hydrocarbons in the gas and increasing the percentage of CO & H₂ in the gas (due to the endothermic reaction represented by C + H₂O = CO + H₂) All of these Controlling the dust nuisance while charging the coal Prevention of clinker formation in the oven Reducing the cracking of hydrocarbons in the gas and increasing the percentage of CO & H₂ in the gas (due to the endothermic reaction represented by C + H₂O = CO + H₂) All of these Controlling the dust nuisance while charging the coal Prevention of clinker formation in the oven ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Gasification of the solid fuel converts its organic part into combustible by interaction with air/oxygen and steam so as to obtain a secondary gaseous fuel of high calorific value having no ash. Gasification reactions are normally carried out at about __________ °C. 1700-1800 1400-1500 400-500 900-1000 1700-1800 1400-1500 400-500 900-1000 ANSWER DOWNLOAD EXAMIANS APP
