Explain the types of tube failure that may occur innthe initial stage of boiler operation till stabilization?

During the initial stage of boiler operation, until the system reaches a stable operational phase, several types of tube failures can occur. These failures are often related to start-up conditions, improper handling, design flaws, or material weaknesses. The initial period of boiler operation is critical, as it involves high thermalRead More

Analysis of the statement on mill outlet temperature:

Points in favor of higher mill outlet temperature (up to 100 – VM): Risks and precautions for high mill outlet temperature: Overall recommendation: Running the mill at a higher outlet temperature, up to the recommended limit (100 – VM), can offer several benefits in terms of combustion efficiency, mill performance, and clinker reduction. However, careful monitoringRead More

Causing of fluctuations in working pressure of a boiler

What are the causes of fluctuations in working pressure of a boiler? (AP_BOE_2010_P_1) 1. **Fluctuation in load:** This is a common cause of boiler pressure fluctuations. When the demand for steam increases, the boiler pressure will drop as the boiler tries to generate more steam. Conversely, when the demand forRead More

Phosphate Dosing

Why phosphate dosing required in boiler ? (Central BOE-2021) Phosphate dosing is required in boilers for two main reasons: to prevent scaling and corrosion, and to maintain proper pH levels. **Scale prevention** Scale is a hard deposit that can form on the inside of boiler tubes and other components. ItRead More

Why is the safety valve of a superheater set at a lower pressure than a safety valve of a boiler drum? (Central BOE-2021)

The safety valve of a superheater is set at a lower pressure than a safety valve of a boiler drum to protect the superheater tubes from overheating and damage. When the pressure in the boiler system rises too high, the safety valve on the superheater will open first, allowing someRead More
