if oil is mixed with water,oil will form a layer over the
surface of the water this is because the sp.gravity of oil
is lesser than water so it floats over the surface.this
resists the formation of steam to a large extent that is it
doesnot make evaporation of water instead foaming occurs

If oil is mixed with water foaming will occur in boiler
steam drum.drum water level goes up and down it will
confusing the boiler operator .drum level trasmitter will
block because of air lock. steam purtiy will be affect.

Answer / chaitanya pithawa

this will not allow to evaporate the water properly and the

stick with surface and proper heat transfer might not be
occured,if oil evaporates then it will affect the turbine
blading.

Answer / saurabh agarwal

Oil when mixed with water- Emulsion takes place. When combustion of oil happens a micro-explosion takes place which atomizes the the water droplet. Thus, higher surface area created supports better heat transfer to the fluit in lesser time.
