Gentlemen, by utilizing waste heat to raise the original feed temperature from 40°C to 80°C, how much steam can be saved? How to calculate it?
The sensible and latent heat of steam is calculated through the specific heat capacity and flow rate of the raw materials, in order to determine the amount of steam required
Quantity of material * specific heat of material * temperature difference; this is the heat value! In terms of equivalent steam volume!
First, find the standard molar enthalpy of formation of the raw materials; then use the enthalpy method to calculate the actual heat load. Once the heat load is known, the amount of steam required can be determined based on sensible heat and latent heat.
The total heat is calculated by multiplying the temperature difference by the temperature coefficient of heat transfer efficiency and the total volume
