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
