Why should boilers be fired slowly during startup?

To reduce fuel consumption
To allow for proper cleaning
To ensure uniform expansion
To optimize pressure quickly

The correct answer is: To ensure uniform expansion

Firing boilers slowly during startup is crucial for ensuring uniform expansion of the boiler components. When a boiler is heated too quickly, the rapid temperature increase can lead to uneven expansion of metal parts, which may cause stress and potential damage. Uniform expansion helps maintain the integrity of the boiler structure and prevents issues such as warping or cracking of the materials. Additionally, a gradual increase in temperature allows for better control of steam production and pressure build-up, ensuring that the boiler operates safely and efficiently as it reaches its desired operating conditions. Maintaining this careful approach during startup is essential for the longevity and reliability of the boiler system.
