Liquid heating
Liquid heating is a common way of heating and is applied mainly to the heating of liquids such as water, oil, and chemical drugs.
1. Direct heating: The heating element of the heater is inserted directly into the container or storage tank where the liquid is. The current enables the heating element to generate thermal energy and to accordingly heat the liquid directly. This approach is indicated for small containers or occasions where local heating is needed.
2. External heating: The sheathed heater is installed in the external surroundings of the liquid storage tank and sends thermal energy to the surface of the liquid to heat it. This approach is indicated for large liquid storage tanks and helps realize even heating effects.
3. Keep-warm: Upon external heating, the sheathed heater also exercises the keep-warm function to ensure that the liquids remain stable once the target temperature is reached. This is crucial to applications where maintaining a specific temperature over an extended period of time is needed.
4. Flow rate, flow, and target temperature: While suitable equipment for sheathed heaters is being designed, one needs to consider the flow rate, flows, and the required target temperature of the liquid. Based on changes to these parameters, the power and configuration of sheathed heaters can be adjusted to ensure that the optimal heating results are reached.
5. Scope of application: Liquid heating is widely applied in respective industries, including food processing, chemical engineering, pharmaceuticals, and cooling systems, among others. Choosing a suitable sheathed heater and heating approach depends on the substantial requirements of the specific application.
Solid heating
Solid heating plays an important role in respective manufacturing processes. Manufacturers usually choose suitable heating approaches and equipment according to their substantial demand in order to ensure the high performance of the specific process and high quality of products.
1. Melting: It is a process where raw materials are dissolved into the liquid state to facilitate subsequent processing. This is very common in the manufacturing of metals and plastics.
2. Pressing: It is a process where the material is made into the required shape. The material is usually softened under high temperatures and pressed into shape. This can be applied to processes such as metal forging and rolling.
3. Welding: It is a process where metal components are heated and melted and then solidly combined. This is common in the manufacturing of metal structures.
4. Assembly: It is a process that involves the combination of different components. Usually heating makes it easier to combine components.
5. Importance of temperature control: In these solid heating processes, precise temperature control is essential. Incorrect temperature control can impact quality of the products undesirably. Proper temperature management is particularly needed for different processes and materials.
Gas heating
Gas heating involves the heating of gas to a specific temperature in order to meet the demand of a manufacturing process. It is widely applied, can meet the needs in different fields, and ensures proper heating and control of gas in the manufacturing sector and in daily life.
1. Drying and treatment in the manufacturing of products: While products are being manufactured, it is often needed to dry coated or plated items. Sheathed heaters heat the gas inside the container directly or indirectly to the surroundings of the container when placed outside the container to accordingly accomplish drying and treatment of the gas.
2. Indoor heating and food heating in daily life: Heating technology is widely applied in daily life, too, to heating inside a vehicle and a building and to heating and keeping food warm. For such applications, it is required to ensure that the required comfort or food safety is fulfilled with the gas at specific temperature.
3. Bakery and food heating: In bakery and food production, sheathed heaters are applied to ovens and other equipment for baking pastries and cookies, among others. By controlling the temperature of gas, it ensures that the food reaches its ideal state during the heating process.
4. Construction and industrial heating: In construction and industrial fields, sheathed heaters are used in the heating systems of buildings and some unique industrial processes to ensure that the gas reaches a suitable temperature when needed.
