Selection and advantages of materials or air heating

How to choose a good method to maximize efficiency in the heating process of materials or air. Firstly, we are familiar with three common types of heating methods in this field:

1. Heating materials or air through combustion;

2. Heating materials or air through electricity;

3. Heating through other sources of energy;

By comparison, electric heating still has significant advantages over combustion heating and other energy sources of heating.

1. The electric heating process is clean and hygienic, and does not pollute the heated materials or the environment;

2. High thermal efficiency of electric heating: In terms of the thermal efficiency of material heating process, coal-fired heating is about 12-20%, fuel heating is about 20-40%, gas heating is about 50-60%, steam heating is about 45-60%, and electric heating can reach 85-95%;

3. Safety: There is an open flame for combustion heating, which can be carried out in environments with flammable and explosive objects. The danger of combustion heating is high, and electric heating is generally necessary. At the same time, there are high requirements for the explosion-proof performance of electric heaters;

4. The electric heating power can be easily adjusted, making it easy to adjust the temperature and achieve automatic control;

5. There is no need for supporting facilities such as combustion support, smoke exhaust, slag removal, and dust removal. The system is simple, compact, and easy to maintain, so it can be installed and operated under various special environmental conditions.

The temperature control and thermal efficiency of materials or air in electric heating are quite high. In fact, choosing a high-quality electric heating element equipment is also an essential step. In a large number of practical applications, electric heating element series can be divided into single end heating tubes, U-shaped heating tubes, fin heating tubes, flange heating tubes, titanium heating tubes, PTFE heating tubes, etc. according to different customer needs
