Calculation of energy consumption in rotary kilns
Thread Content
For a rotary kiln with a power of 55 KW and an effective volume of 142 cubic meters, where the preheating temperature is raised from 20 degrees to 800 degrees before 2 tons of material are added and baked for 1 hour, how much energy is required in this process?
If there is power, then multiplying it by time gives energy, right?
Power multiplied by time gives only the energy expended by the kiln motor in doing work; I want to know how to determine the amount of fuel consumed
Isn’t the heat value of fuel multiplied by its weight equal to the heat?
The problem is that I don’t know the amount of fuel required. What I really want to ask is how to determine the amount of fuel needed to maintain the temperature for 1 hour once preheating has reached the target temperature
