Quantity of steam necesary to heat a water tank
(OP)
How can I calculate the quantity of steam to heat in 1 hour, 6000 kg of water in a simple jacket tank, the inlet pipe of the tank is 1". I need this because I want to select a firetube boiler to replace the one we have now and prevent a future, plant growth.
Thanks in advance for your help.

RE: Quantity of steam necesary to heat a water tank
The amount of heat you need is essentially set by the mass of water, its heat capacity and the temperature change. Divide that by 1 hour (your heat up time) and you know the rate you need to add duty to the system.
Condensing steam to do this releases about 970 BTU/lb at atmospheric pressure (as the condensing pressure increases, you get less heat out of a pound of steam, or kg or whatever mass units you want to use).
Divide the heat rate by the latent heat of steam and that's the flow rate of steam you need (actually, the average flow rate over the 1 hour period). You also need to determine if you have enough area in your jacketted tank to transfer that much heat in your desired period of time.

I need to heat te water from 20°C to 90°C
