What is an important precaution before burning coal in a combustion system?

Before burning coal in a combustion system, an important precaution is to measure the quantity of coal accurately. This step is critical as it ensures the right fuel-to-air ratio is achieved for efficient and safe combustion. Accurate measurement helps maintain optimal performance of the system, preventing inefficiencies like incomplete combustion or excessive pollutants being released into the environment.

Furthermore, ensuring that the quantity of coal used is suitable for the design of the combustion system aids in achieving the desired output while minimizing the risk of operational issues such as clinkering or excessive heat generation which can lead to equipment damage or safety hazards. This practice promotes not just operational efficiency, but also compliance with environmental regulations related to emissions.
