What is the temperature limit for preheated air when operating a stoker-fired boiler?

The temperature limit for preheated air when operating a stoker-fired boiler is set at 350°F. This limit is important to ensure the safe and efficient operation of the boiler. Preheating the air helps to improve combustion efficiency by ensuring that the fuel burns more completely, which can enhance the overall thermal efficiency of the system and reduce emissions.

Operating with preheated air at temperatures exceeding 350°F could potentially lead to safety hazards, including the risk of flashback or overheating components of the boiler system. High temperatures can also damage equipment or create an environment that may lead to combustion issues.

In the context of boiler operation, adhering to the temperature limit for preheated air is essential for maintaining the integrity of the boiler, ensuring safe operations, and optimizing combustion processes. This understanding emphasizes the importance of following manufacturer specifications and safety guidelines for boiler operation.
