What term refers to a wall that deflects gases downward in a crematory structure?

The term that refers to a wall designed to deflect gases downward in a crematory structure is known as a drop arch. This architectural feature is specifically engineered to manage the flow of gases produced during the cremation process. By directing these gases downward, drop arches help to enhance the efficiency of the cremation chamber and improve the overall combustion process. This design minimizes the potential for the escape of harmful emissions and assists in maintaining an optimal internal environment within the crematory, which is essential for effective and compliant cremation operations.

Understanding the role of a drop arch within the crematory context is crucial, as it plays a significant role in both operational efficiency and regulatory compliance regarding air quality and emissions management.
