What are Tuyeres also known as?

Tuyeres are often referred to as air-admitting grates on stokers. They play a crucial role in combustion systems, particularly where stoker-fired boilers are involved. Essentially, tuyeres allow air to enter the combustion zone, which is necessary for supporting the combustion of fuel and optimizing efficiency. The design and placement of tuyeres are critical because they ensure that the right amount of air mixes with the fuel, contributing to a complete and efficient burn.

While other options such as fuel hopper doors, water walls for cooling, and pressure relief valves all serve important functions in their respective applications, they do not relate to the specific function of tuyeres in allowing air to enter the combustion space. Fuel hopper doors are mechanisms for managing fuel in a stoker, while water walls refer to cooling surfaces in boilers that protect against overheating. Pressure relief valves serve to control pressures within a system, ensuring safety, but again, this is a separate function from that of tuyeres. Hence, the designation of tuyeres as air-admitting grates on stokers accurately reflects their purpose and functionality in the combustion process.
