What is the object of providing baffles in between water tubes in a babcock-wilcox boiler?
To regulate water flow
To regulate steam flow
To have better contact of flue gases with water tubes
To prevent buckling of water tubes
A babcock-wilcox boiler is classified as a water tube boiler because
It has a large bank of tubes and a steam drum
