What are tuyeres primarily used for in stokers?

Tuyeres are primarily used to admit combustion air into the combustion chamber of stokers. This is crucial because a proper supply of air is necessary for efficient and complete combustion of the fuel being burned. When air is introduced through the tuyeres, it enhances the combustion process by providing the oxygen needed for fueling the fire, which results in better combustion efficiency and the production of more energy.

In stoker operations, ensuring that the airflow is correctly managed via the tuyeres can influence the overall performance of the boiler system, including its ability to maintain optimal temperatures and reduce emissions. This direct impact on the combustion process is the primary reason why tuyeres are focused on for air admission rather than for purposes like measuring temperature or cooling the system.
