Zhengzhou Yishang Machinery Equipment Co., Ltd. provides a professional calculation method for matching natural gas burners with sand dryers to ensure optimal drying efficiency and energy utilization. The following formula is used to determine the appropriate burner model, demonstrated here with a 15-ton sand dryer as an example.

Formula:
15 × 0.1 = 1.5 × 60 = 90 ÷ 0.6 (or adjusted by +0.8 factor)

Step-by-Step Explanation:

• 15: Refers to the 15-ton capacity of the sand dryer.

• 0.1: Assumes the average moisture content of the sand is 10%.

• 0.15: Represents the total water content (in tons) to be removed from 15 tons of sand.

• 60: Denotes the heat energy required to evaporate 1 ton of water, equivalent to 600,000 kilocalories.

• 90: Indicates the preliminary theoretical heat load (in 10,000 kcal/h) required for the dryer.

• ÷ 0.6 or + 0.8: Adjustment factors applied to align the theoretical value with practical operating conditions, ensuring the burner selected meets real-world efficiency and safety standards.

Operational Insight:
During operation, the sand flows through the inner drum of the dryer with a retention time of approximately 0.3 seconds per fall, ensuring rapid and uniform heat exchange.

This formula reflects Zhengzhou Yishang’s engineering approach to combining theoretical calculations with practical adjustments, providing customers with reliable and efficient burner matching solutions for their sand drying systems.
