Excuse my English.

 

Dear, I am doing my project of memory and partly it must conduct an analysis of the feasibility of putting into operation a boiler, that while I keep the approximate amount of steam that I produce, I could not find a way to estimate consumption water and fuel would be. Well, the information that is provided to me is:

 

Caldera Type: Firetube two phases

Steam production capacity of 3000 kg / h

Working pressure: 8 kg / cm2

Heating surface: 155.4 m2

 

With a burner of the following characteristics:

 

Diesel Fuel

Q: Min 95 kg / h 1127 kW - Max 285 kg / h 3380 KW

 

I have the tank capacity of the boiler, but I think it is around 6000 m3, and the temperature of water entering this is approximately 35 ° C (if, should be higher).

 

As I can calculate the consumption of water or oil that would have the boiler with the production of a certain amount of steam? there any way to know the information I have?

 

Greetings!

You should specify the steam you want to produce (Saturated or superheated) &  please attach PFD of the same.

Dear Kamikase

 

for BFW (i.e. boiler feed water) consider the amount of steam that you need + 2 ~ 5 % (for boiler blowdown + Loss)

 

for required heating energy, consider the latent heat of steam (at specified pressure) add extra heating energy for super heating the steam. LHV of fuel is used to calculate ideal amount of required fuel. consider boiler efficiency (e.g. 85~90%) and calculate actual required fuel.

 

good luck
