Answer / atul $onawane

The reduction in excess air means higher furnace temperature
which ultimately results in clinker formation,incomplete
combuton of fuel and results in higher operating cost.

Answer / anwar ashwak hussain

if we supply theoretical air it is not sufficient to
perform complete combustion. incomplete combustion leads to
co, so, NO formation which are hazardous to environment and
we also loose co which can be used as fuel. if we supply
higher or lower amount of excess air leads to decrease in
furnace efficiency. so we should optimize the excess air
where furnace efficiency is high.

Answer / sarav

Simply we can say to ensure the complete combustion of fuel.
Which will also reduce the toxic gas emission (CO) and also
results in effective fuel utilization which reduces the
operation cost.

Answer / vinayak m. desai

excess air give complete combustion of the fuelmeans we get
higher temp and economy operation

Question 42 - According to Margules Equation, P = x(1) p(1) g(1) + x(2) p(2) g(2) for a two-component mixture where P is bubble pressure, x is mole fraction, p is saturation pressure, g is constant given by ln g(1) = x(2) A x(2). Find the value of A as a constant when P = 1.08 bar, p(1) = 0.82 bar, p(2) = 1.93 bar in a 50 : 50 mole fraction mixture. Estimate the pressure required to completely liquefy the 30 : 70 mixture using the same equation, by proving P = 1.39 bar. Take note that ln g(2) = x(1) A x(1), ln g(1) = x(2) A x(2).
