Yellow phosphor is a high energy-consuming product.The temperature distribution inside and outside of the furnace is shown through calculations using heat transfer formula based on softening temperature and melting temperature of material in the furnace recommended by related reference and temperature measurement on the inside and outside of a phosphor furnace.The heat distribution on the inside and outside of the phosphor furnace is discussed based on analysis of factors influencing the size of the electrode bath.Phosphor practitioners must compound the appropriate materials according to the chemical composition of the phosphate ore,the dosage of coke and silica,and shall adjust the 'coke ratio' and I/E value of the materials at any time when needed,and control the material particle size to maintain long-term safety operation of the phosphor furnace at the optimal condition so as to reduce energy consumption.
