Thanks it's very useful..

Thanks for feedback 🙏.

Thanks for ur efforts .It's very helpful to Bee aspirants like me..

So nice of you. Share and do subscribe the channel.

Sir which moisture should be taken for calculation , Inherent Moisture or Total moisture?

[@viralsolanki8218]

For loss due to moisture present in fuel

[@beeauditorsexam9126]

For the head (loss due to moisture present in fuel) you have to consider only the moisture present in fuel.

Sir.. specific heat of water is taken 0.45..But in mostly 1 is taken..pls explain

[@beeauditorsexam9126]

When water is in liquid phase specific heat is 1 and when in moisture/vapor phase it is 0.45 unit being kcal/Kg degC

@@beeauditorsexam9126 Thanks sir..I must appreciate your efforts..The tutorials are extremely good and easy to understand..Rather than using the formulas you are deriving them..This is the uniqueness of your channel..Pls upload videos more videos covering all topics relevant to EM / EA ..I can't find any video in you tube which has such a good explanation on boiler efficiency and other topics too..

[@viralsolanki8218]

Sir, in Heat loss due to moisture present in air considered only m*c*∆t part, latent heat part not considered due to moisture is already in vapor form, FD air pass through APH in that its temp increases around 145-160°c, so all moisture evaporates in vapor form, so it is consuming heat from West heat not from fuel combustion heat, so that part not accounted?

[@beeauditorsexam9126]

Here we are interested only in the heat loss of the fuel we are using as we are concerned with efficiency of boiler. The installation of Air Preheater is increasing the efficiency of the boiler system as a whole and not of boiler individually.

[@rishabgarg4233]

How can specific heat of water be 0.45 kcal/kg?? Isn't by definition it should be 1 kcal/kg?

[@beeauditorsexam9126]

Specific heat of water is one while that of moisture/ water vapour is 0.45.

[@rishabgarg4233]

@@beeauditorsexam9126 if water is already in vapour form then why latent heat is added in the equation?
