Hi

i need help about heat loss from a storage tank.
i want to calculate the steam consumption for a 2000 tons edible oil tank
in order to maintain desired temperature.

Although there are approximations and empirical methods,
they need so many variable and i still dont trust them too much.
Because heat transfer calculations are cumbersome and not reliable.

i have two methods that i am not sure if they are reliable:

These are,

1-Collecting the condensate all day

So this is my Real steam consumption (?)

2- Cut the steam , Let the tank cool for a while , Find the Temperature drop ,

then dQ=mc dt

Thats my heat loss and also my energy input


So Do you think it works?

Hi Levent01 ,

I will use the 1st approach for several days or weeks and will confirm doing basic calculation .Both methods are subject to variation ( season , wind , day /night) . Nothing is perfect .If you have a  chance let you install a steam meter to ease your work .

What is the purpose of the work ? to improve insulation ,...

By the way you can buy an infrared thermometer or pyrometer to visualize the losses doing a mapping of the tank .

Hope this helps.

Thank you so much for your help.

My only purpose is curiosity so they will not let me buy equipments for my pleasures .

i know it depends on forced convection and weather. thats why i dont want to find heat transfer coefficient.

 

By the way Did you confirm the results with attached file?

Hi,

 

Yes , as an order of magnitude  !

 

Attached an other resource to support your work.

Good Luck .
