What is the recommended method to prevent a fire in your pulverizer?

The recommended method to prevent a fire in a pulverizer involves increasing fuel and cold air. This practice helps to ensure that there is a proper balance of fuel and air, which aids in effective combustion without allowing for excessive heat buildup that could lead to a fire.

In a pulverizer, materials such as coal are ground into a fine powder to improve their efficiency during combustion. However, if the pulverized fuel is not adequately mixed with cold air, the temperatures can rise too high, creating an environment where fires can ignite. By increasing cold air flow along with the fuel, you dilute the combustion mixture and lower the overall temperature, significantly reducing the possibility of fire.

Ensuring that there is an ample supply of cold air during the processing phase is crucial since it assists in cooling the pulverized material, maintaining safe operating conditions. This method not only enhances safety but also optimizes the combustion process.

Other options, while they may relate to boiler safety in different contexts, do not effectively prevent fires in the specific environment of a pulverizer. Decreasing air flow would limit oxygen availability, potentially leading to incomplete combustion and increased temperatures. Using fireproof materials is generally a good practice for structural safety but doesn't directly address the internal processes of the pulverizer. Maintaining
