The working principle of heat transfer oil furnace


2022-04-29 14:40

The heat transfer oil furnace is also called the organic heat carrier furnace, commonly known as the heat transfer oil furnace boiler, and the official name is the thermal oil furnace. It is a new type of thermal energy equipment that uses coal, oil and gas as fuel and heat-conducting oil furnace as circulating medium for heating. Thermal energy conversion equipment, usually also use "MW" (megawatt) to indicate the capacity of the furnace. The advantage lies in "high temperature and low pressure", stable operation and is widely used. The principle of the heat-conducting oil furnace: it uses coal, heavy oil, light oil, combustible gas and other combustible materials as fuel, and the heat-conducting oil furnace is the heat carrier. The circulating oil pump is used to force the liquid phase to circulate, and the heat energy is transferred to the heat-consuming equipment, and then returned to the reheated once-through special industrial furnace. Widely used in petrochemical, textile, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heating, carton production, vegetable dehydration, baking paint, casting sand mold drying, etc. The heat transfer oil furnace is a new type of special boiler with heat transfer liquid as the heating medium. With low pressure and high temperature working characteristics. With the development of industrial production and the advancement of science and technology, heat transfer oil furnaces have been continuously developed and applied. Although the working pressure of the heat transfer oil furnace is relatively low, the temperature of the heat transfer fluid in the furnace is high, and most of them are flammable and explosive. Once leakage occurs during operation, it will cause fire, explosion and other accidents, and even cause casualties and property. loss. Therefore, the safe operation and management of the organic heat carrier furnace must be highly important. Because it has the advantages of high temperature (above 320°C) and low pressure (0.3-0.5MPa), and its heating temperature can be precisely controlled, it can replace the original steam boiler for heating. At the same time, the equipment does not require water treatment equipment and has no heat loss such as running, running, dripping, and leaking from steam boilers, so it saves one-time investment and has low operating costs. It is a safe, efficient and energy-saving heating equipment. The heat-conducting oil furnace boiler is a direct-flow special heat-conducting oil furnace developed based on the design thinking of forced circulation. The closed cycle heat supply is connected to the atmosphere, which can prolong the service life of the boiler. The liquid phase transports heat energy, with small heat loss, significant energy saving effect and good environmental protection effect. Due to the coil type structure, the heating surface is sufficient, which makes it have high thermal efficiency. The heat transfer oil furnace boiler is characterized by countercurrent heat exchange, and the difference between the temperature of the combustion exhaust gas and the outlet temperature of the heat transfer oil is below 30 °C. The excellent structure of the heat transfer oil furnace mainly operates at a lower pressure and obtains a working temperature below 450 °C, which has the characteristics of low pressure and high temperature.
