We are sending steam to bladder (steam may be wet) but we are maintaining required temperature . If we send dry steam also we can maintain that temperature but what about the heat transfer to the bladder in the first case and the second case.
You got me at the concept of wet and dry steam. The only thing I've ever heard referred as dry steam was the moisture cloud generated when filling a liquid nitrogen or helium dewar. Could you elaborate about what the two types of water vapor (wet and dry steam) you are talking about?

Given that the heat available for transfer is the sum of the latent heat available in the steam plus the heat represented by the temperature of the condensate above the medium being heated then, clearly, sending dry steam to the load will achieve better heat transfer than sending wet steam.
The principle is used to justify steam traps in the lines between the boiler and the load, and also to justify insulating the steam line.

I would suggest that in most cases steam traps and insulation are more easily justified as a level of protection against the potential peronel injury/loss of life, damage to equipment and plant downtime that may result from failures due to wet steam errosion corrosion and drop impingement.
