What is the purpose of a draft gauge in boiler operations?

The purpose of a draft gauge in boiler operations is primarily to measure the pressure difference that drives combustion air through the system. This pressure difference, often referred to as draft, is crucial for ensuring that the combustion process operates efficiently.

In a boiler, proper airflow is essential for maintaining combustion stability and efficiency. The draft gauge provides real-time monitoring of the pressure difference between the combustion chamber and the atmosphere. This measurement allows operators to evaluate whether there is sufficient draft to pull in adequate amounts of air for combustion while also ensuring that exhaust gases are effectively removed.

Maintaining the correct draft is vital not only for efficient operation but also for safety, as improper draft can lead to incomplete combustion or the potential for dangerous backdrafts. Thus, the draft gauge plays a pivotal role in both operational efficiency and safety management within boiler operations.
