Hi Everyone, I am currently working on a new project and I got some problems and really need your advice and help.  I need to determine the capacity of a Heavy Fuel oil Tank.  The Factory that will be using this tank will produce 700 tons of steam per month.  I have this only as data, can you please help me to determine what calculations should I proceed with to come up with a tank capacity that will prevent the factory from running out of fuel.  Another info is that the factory work 5 days per week, 24/7

 

Thanks a lot and hope to hear from you very soon.

 

Schematic:

 

X Litres of HFO Tank -----> Burner ------> Boiler -------> 700 tons Vapor/month

First let us get the 7000 tons vapor / month unit into something everyone is familiar with:

 

I am assuming the ton  is metric ton

 

700 tons = 700 tons * 1000kg/tons=7e5kg

 

1 month~ 4 week*5 days/week*24hr/ day=480 hours

 

700 ton/month= 7e5 kg/480 hr= 1458 kg/hr

 

So the design question will be in order this amount of steam what is the fuel oil requirement in the burner

A burner is supposed to be part of a boiler.

 

the fuel oil is what keeps the fire going in the burner

 

So in order to know how much fuel oil needed

 

you need to know the fuel oil requirement for the burner.

 

After that you can then determine how much is needed in a week, a month, in a quarter or a year.

 

Let say you want to refuel every month and the burner requires x kg/hr of fuel oil,

 

then in a month you need x kg/hr* 1 month*4weeks/month*5 days/week*24 hr/day=480x kg

 

if the density of the fuel oil is y kg/m3 then volume of fuel oil in a month is 480x/y m3

 

using L/D =3 for the tank you can determine  what the lenght and diameter of your tank should be.

Hi Edu,

 

Thanks a lot for those info, it is very useful indeed, but I am confused about the length to diameter ration, what is it exactly, i try to researcha bit on that but still do not get it why it is equal to 3.

 

Thanks again

Roy

 To give you an idea where i will be placing the tank here here is a sketch:
