The heat source of the flash dryer can be selected according to different process requirements and equipment design. Common heat sources are as follows:
1. Coal: Coal is an economical choice if environmental protection allows. Hot air is provided by adding a coal-fired hot air furnace in front of the flash dryer. However, the cost of purchasing equipment in the early stage may be slightly higher when coal is used as a heat source.
2. Liquefied gas: The cost of liquefied gas as a heat source is relatively low, but when using liquefied gas, it is supplied in bottles and needs to be frequently replaced when used in large quantities, which may bring some inconvenience.
3. Natural gas: Natural gas is a clean and efficient energy source. After the natural gas is decompressed through the pipeline and input into the burner, it can generate hot air above 300℃ in the gas hot air furnace, which is very suitable as a heat source for the flash dryer.
4. Diesel: Diesel can also be used as a heat source for the flash dryer, but the energy consumption is relatively high and the cost may be higher.
5. Steam + electric heating compensation: Steam is a commonly used heat source medium with the advantages of high temperature and high heat. In China, the combination of steam + electric heating compensation is very common, because the steam temperature is generally around 150℃, and for some materials that are not subject to temperature restrictions, electric heating can be used to supplement. This heating method is easy to operate.
6. Electricity: Electric heating is a convenient and environmentally friendly heat source method, but the cost may be relatively high. For some occasions with special requirements for heat sources, electric heating may be a suitable choice.
In summary, there are many choices of heat sources for flash dryers, and you can choose the appropriate heat source method according to actual conditions and specific needs.
