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

Three solid objects of the same material and of equal mass – a sphere, a cylinder (length = diameter) and a cube – are at 5000C initially. These are dropped in a quenching bath containing a large volume of cooling oil each attaining the bath temperature eventually. The time required for 90% change of temperature is smallest for a) cube b) cylinder c) sphere d) equal for all the three whyyyyyyy???????

Question 61 – A biochemical trolley of mass 15 kg is towing a trailer of mass 5 kg along a straight horizontal pathway. The trailer and the trolley are connected by a light inextensible tow-bar. The engine of the trolley exerts a driving force of magnitude 100 N. The trailer and the trolley experience resistances of magnitude 10 N and 30 N respectively. (a) Form 2 equations with unknowns T and a, that represents the equilibrium for the 2 systems of the trolley and trailer. (b) Solve the simultaneous equations from the 2 equations that are obtained in part (a) of this question. T is the tension of the tow-bar and a is the acceleration.
