Thermal oil boilers are nothing more than hot oil heaters, which heat circulating oil to very high temperatures, such as 250 degrees. Celsius is like a water/steam boiler, not water, but hot fluid or oil. Heat-conducting oil boilers usually have fuel oil gas heat-conducting oil furnaces, electric heating heat-conducting oil furnaces, etc. Under the premise of promoting energy saving and environmental protection, it has gradually replaced the traditional high-pollution and high-energy boilers and has become an indispensable thermal energy equipment in all walks of life.
The heat-conducting oil furnace is a new type of special boiler using heat conduction fluid as the heating medium. With low pressure and high temperature working characteristics. Coal, heavy oil, light oil, combustible gas and other combustible materials are used as fuel, and heat-conducting oil furnace as heat carrier. The circulating oil pump is used to force the liquid phase circulation, and the heat energy is sent to the heating equipment, and then returned to the reheated DC special industrial furnace. Boiler widely used in petrochemical, textile, printing and dyeing, plastic, rubber, food processing, wood processing, asphalt heating, carton production, vegetable dehydration, baking paint, casting sand mold drying, etc. With the development of industrial production and the advancement of science and technology, the thermal oil furnace has been continuously developed and applied.
The advantages of heat conduction oil boiler compared with traditional boiler
1. Closed circulation system, less heat dissipation, energy-saving energy, lower energy consumption
2. Low voltage operation, high temperature, safe and reliable
In the heat conduction oil heating system, the heat conduction oil is liquid phase forced circulation to transfer heat, the vapor pressure is very low, the transport pressure is generally around 0.5Mpa, but the heating temperature can reach 300 ℃, and the general steam boiler heating temperature is 170 ℃ , The steam pressure has reached 0.8Mpa. To further increase the temperature, the steam pressure should increase accordingly, and the pressure rating of the entire system should be increased. Not only the cost is to be high, but also the unsafe factors are also very large.
3. The temperature is stable and controllable to meet users with different temperature requirements
4. Less equipment and cost saving:
The heat conduction oil heating system has few equipment, no water treatment equipment such as boiler water softening or deionization is required for the steam boiler heating system, no boiler water blowdown equipment is required during operation, and huge water storage equipment and high pressure inlet are not required Water pumps, etc., can save a lot of manpower and material resources.
5. It can be used for cooling system, and waste heat can be used:
When thermal oil is used for cooling system, unlike water cooling, it is limited by temperature because the boiling point of water is 100℃, and scale will be generated when operating at high temperature, and the initial boiling point of thermal oil is above 300℃, which can improve the cooling. At the same time, it will not produce scale, because of the high temperature; the use of waste heat also brings convenience.
