Abstract

PURPOSE:To control the temperature for extraction without using the heat transfer coefficient alpha, by using the heat balance formula at wich it is postulated that the total amount of heat output and the total amount of heat input at each of the zones of the hating furnace are equivalent, and by controlling the flow rate by estimating and calculating the necessary amount of the fuel to be charged.
