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
Reducing Boiler Feed Pump Oversizing
Is it possible to reduce feed pump capacity with the oversized existing pump? If so, how? (AP_BOE_2010_P_1) Yes, it is possible to reduce feed pump capacity with an oversized existing pump. There are several methods that can be used to achieve this, each with its own advantages and disadvantages. **Impeller trimming:**Read 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
Soot blowing procedure
Describe soot blowing procedure (AP_ BOE_2010_P_1) Soot blowing is a crucial process in maintaining the efficiency and lifespan of boilers. It involves using high-pressure steam or air to remove soot and ash deposits from the boiler’s heat transfer surfaces. These deposits can impede heat transfer, leading to reduced boiler efficiencyRead 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
