Dear all,

What is the effect of moisture in input Raw Materials like - Ore & Flux and Coke in Blast Furnace.

Some losses like - Latent heat reqd. to evaporate the water is quite visible, however can we exactly quantify the other process related losses?

Can anybody help me in calculating the above losses?

Regards

Productivity Loss In Blast Furnae Due To Moisture

Dear all,

By feeding moist Raw Matrerails like Ore, pellets & Coke, we add moisture into the BF.

For deciding the coke rate i.e. Coke MT in per Ton of Hot Metal produced, the furnace operator take care of the average moisture.

May I know the kg/THM of Coke being added for the 1% of moisture in the input RM.

Beyond latent heat you have to consider:

pressure, temperature rise, volume of container, and so on as given in the change in specific heat and given in some detail on the following website for Steam Engineering Principles and Heat Transfer :

You also have consider both surface and internal moisture of your products.
