The drying of materials is inseparable from heat sources. Different materials have different requirements for heat source equipment. To choose a suitable heat source, the operating costs and production costs of the equipment should be considered, and the operability of the drying equipment should be considered.
Next, I will introduce you to several different heat sources of drying equipment. The commonly used fuels for drying materials include solid fuel, liquid fuel, gas fuel, heat carrier and electricity. Specifically, there are various combustion materials (coal, natural gas, liquefied petroleum, gas, combustible chemical gas) and air combustion products, water vapor, hot water, electricity.
The selection of different heat sources for drying equipment should meet the following aspects:
- Meet the requirements of product quality: The heating temperature and the cleanliness of the heat source have a great influence on the product quality;
- Meet environmental protection requirements: Some combustion heat sources will produce peculiar smell or smoke during the combustion process, and will produce pollution after being discharged into the atmosphere. Such heat sources should be used with caution.
- Economically and easily available: The selected heat source should be tailored to the location, not only considering the cost of various heat sources, but also considering easy availability.
- Safe and reliable: This is more important for direct-fired heat sources. Some drying equipment is flammable, explosive or oxidized. It is best to use indirect heat exchange heat sources to process such materials. Direct-fired heat sources must have special resistance. Fire or explosion-proof measures.
- Easy to operate: The selected heat source is as easy to operate and automatically control as possible to ensure stable product quality.
If you want to know how to choose a suitable heat source for the dryer, this article tells you through several following aspects.
