Furnace Technology Temperature of a furnace fired with low calorific value fuel gas (i.e. lean gas) can be increased by Preheating the combustion air Oxygen enrichment of combustion air All of these Preheating the fuel gas Preheating the combustion air Oxygen enrichment of combustion air All of these Preheating the fuel gas ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology In practical operation of any furnace, zero oxygen percentage or theoretical CO₂ percentage in flue gas is rarely achieved, because of Imperfect mixing of fuel & air and infiltration of air Use of non-preheated combustion air Use of pulverised solid fuels Use of excessive positive draft in the furnace Imperfect mixing of fuel & air and infiltration of air Use of non-preheated combustion air Use of pulverised solid fuels Use of excessive positive draft in the furnace ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology Which of the following accentuates clinker-ing troubles on furnace grate burning coal? All of these Thick firebed and preheated primary air Low reactivity of carbonised residue containing high proportion of iron & sulphur Low forced draft & fuel bed temperature All of these Thick firebed and preheated primary air Low reactivity of carbonised residue containing high proportion of iron & sulphur Low forced draft & fuel bed temperature ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology Overfire burning in a furnace is a phenomenon characterised by None of these Burning carbon monoxide and other incombustible in upper zone of furnace by supplying more air Supply of excess fuel Supply of excess air None of these Burning carbon monoxide and other incombustible in upper zone of furnace by supplying more air Supply of excess fuel Supply of excess air ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology Higher furnace temperature can not be achieved by use of a lean fuel gas in the furnace by Preheating the fuel gas Increasing the draft in the furnace Preheating the combustion air Oxygen enrichment of combustion air Preheating the fuel gas Increasing the draft in the furnace Preheating the combustion air Oxygen enrichment of combustion air ANSWER DOWNLOAD EXAMIANS APP
