Analyze which factors determine the working capacity of the drum dryer equipment

The drying capacity of a drum dryer is influenced by several key factors, including the moisture content of the material being processed and the type of heat source used. When dealing with high-moisture materials, insufficient drying can result in products that are still slightly damp, which can affect the final quality. Therefore, selecting the appropriate heat source is crucial to achieving efficient and effective drying. Heat sources for drum dryers vary widely and are typically categorized based on the fuel they use—such as coal, fuel oil, gas, or electricity. They can also be classified by their heating method: direct or indirect. In indirect heating systems, for example, a boiler heats water to produce steam, which then transfers heat to the drying medium via radiators. This method is commonly used in industrial settings for centralized heating, but it has a relatively low thermal efficiency, often around 40%. On the Other hand, direct heating methods involve using combustion gases directly as the drying medium, offering higher thermal efficiency—up to 60-70%—but may introduce contaminants into the product due to smoke. Coal-fired hot blast stoves are another common option, where heat is transferred indirectly to the air, ensuring cleaner output. However, direct combustion systems, while more energy-efficient, may require careful management to prevent contamination. Oil burners have gained popularity in recent years due to their ease of operation, fast temperature rise, stable heat output, and cost-effectiveness, making them a practical choice for many applications. Choosing the right heat source not only affects the drying efficiency but also impacts the overall investment cost, product quality, operating expenses, environmental compliance, worker safety, and automation level.
