Zibo Shengpu Chemical Equipment Co., Ltd. is here to provide you with a detailed overview of the four heating methods used in enamel reaction tanks for achieving high temperatures.
Let's dive right in!
1. **Electric Heating**: This method involves winding electric resistance wires on an insulating layer of the reactor body or placing them on special insulators at a certain distance from the vessel. This setup ensures that there is a small gap between the resistance wire and the reactor, allowing for safe and efficient heat transfer. Electric heating is ideal for precise temperature control and is widely used in various industrial applications.
2. **Water Heating**: Suitable for lower temperature requirements, water heating systems come in two types: open and closed. The open system is simpler, consisting of a circulation pump, tank, pipes, and a control valve. For higher pressure applications, a closed system using high-pressure water is preferred. In this case, a snake-shaped tube is welded onto the reactor’s outer surface, with gaps between the coil and the kettle wall to enhance heat transfer efficiency while reducing thermal resistance.
3. **Heating with Other Media**: When high temperatures are required or when avoiding high-pressure systems is necessary, alternative media can be used instead of water or steam. Common options include mineral oil (operating range: 275–300°C), diphenyl ether mixtures (boiling point: 258°C), molten salts (140–540°C), and liquid lead (melting point: 327°C). These media offer flexibility and are often chosen based on specific process needs.
4. **Steam Heating**: Steam is a popular choice for heating enamel reactors. Below 100°C, low-pressure steam is sufficient. For temperatures between 100°C and 180°C, saturated steam is typically used. When higher temperatures are needed, superheated steam under high pressure becomes the preferred option. This method is reliable and commonly used in industrial settings.
