It is very important to know the temperature when using drum heaters.
The required temperature of the heated material in the oil drum heater equipment determines the working temperature of the thermal oil. The temperature of the thermal oil is higher than the temperature of the heated material. The larger the temperature difference, the smaller the heating area required, and the temperature difference will make the thermal oil The temperature is high, and some chemical materials are easily cracked and cooked at high temperatures, so the size of the temperature difference should be confirmed according to the specific situation, so as not to make the heat transfer oil higher than the limited use temperature or damage the heated material.
The oil drum heater is the key equipment of the heating system. In order to prevent coking above the temperature, the flow rate of the heat transfer oil in the furnace tube should not be too low, but too high a flow rate will increase the flow resistance and consume the circulating pump head and power. The exhaust temperature of the oil drum heater is high, generally 300-400 ℃. An auxiliary heating surface such as an air preheater or an energy-saving water heater should be added to the tail to reduce the temperature of exhaust gas, so as to increase thermal efficiency and save energy consumption.
