• A. Arches
• B. Rectangles
• C. Tiers
• D. Circles

Answer: (C)

In a rectangular furnace, the grates are typically arranged in tiers. This arrangement allows for efficient space utilization and optimal airflow, which is important for the combustion process. Tiers create multiple layers that facilitate the distribution of fuel and help maintain an even burning temperature throughout the furnace. The tiered design also aids in ash removal and enhances the overall efficiency of the furnace by promoting better heat exchange. This is particularly important in industrial applications where maximizing combustion efficiency can significantly impact operational costs and emissions. Other arrangements, such as arches, rectangles, or circles, may not provide the same level of efficiency or could complicate the airflow and heat distribution, which are critical elements in the operation of a furnace. Thus, the tiered arrangement is specifically suited to meet the thermal and operational demands of a rectangular furnace.
