The factors affecting the thermal efficiency of the furnace

According to the principle of heat balance, into the furnace heat is equal to send charging in the sum of heat absorption and heat loss of the material. Among them, into the furnace chamber of a stove or furnace heat including chemical and physical heat of fuel and air and material physical heat; All kinds of heat loss mainly including smoke heat loss, incomplete combustion loss, furnace wall heat loss, etc. ; If it is also includes a solid fuel ash heat loss, etc. In view of the natural gas heating furnace, the main measures to improve the thermal efficiency is to reduce fume temperature, reduce the furnace wall heat loss, The factors affecting the thermal efficiency of the melting furnace and reduce the excess air coefficient can effectively improve the flame temperature, reduce the oxidation burning loss; Improve the uniformity of furnace temperature, can improve the quality of heating, to reduce the oxidation burning loss material, so as to improve the yield of melting furnace per unit time, reducing energy consumption. Then the influence factors of the heat loss is the points: 1, the smoke temperature, the heating temperature of the melting furnace generally between 1000 ℃ ~ 12 0 ℃, and the melting point of aluminum temperature is about 660 ℃, melting furnace chamber of a stove or furnace outlet exhaust temperature above 500 ℃. The waste of energy, heat pollution to the environment. 2, the furnace wall heat loss, in addition to smoke by high temperature melting furnace thermal efficiency, followed by the furnace wall heat loss. Among them, the aluminum and the discharging mouth, the place such as oven heat leak is very big, so choose the reasonable and reliable refractory furnace wall heat loss can be considerably reduced. 3, excess air coefficient, the excess air coefficient characterization of transportation into the furnace combustion-supporting air quantity and combustion theory and the ratio of the volume of air. Excess air coefficient is too large, lead to the smoke contains a lot of not involved in the combustion air, leading to low thermal efficiency. According to the weight of single piece and each weekday need the weight of the liquid iron, can determine the capacity of the medium frequency induction melting furnace. And then determine the power and frequency of the medium frequency power supply.
