Use of MEKO (Methyl Ethyl Ketoxime) Instead of Hydrazine in Boiler Water Treatment
Hydrazine (N₂H₄) has been traditionally used as an oxygen scavenger in boiler feedwater to prevent corrosion. However, due to its toxicity and potential carcinogenic effects, alternative chemicals like Methyl Ethyl Ketoxime (MEKO) are being explored. MEKO as an Oxygen Scavenger Chemical Formula: C₄H₉NO Mechanism: MEKO reacts with dissolved oxygen inRead More
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
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
Impact of Humidity on Cooling Tower Performance
A cooling tower in a power plant is used to remove heat from condenser cooling water by transferring it to the atmosphere through the process of evaporation.The efficiency of this process is affected by the humidity levels in the surrounding air.Understanding how humidity affects cooling tower efficiency is vital forRead More
