Explain the other types of tube failure that may occur during long term operation of the boilers.
During long-term operation of boilers, tube failures become more complex and can arise from prolonged exposure to thermal, mechanical, and chemical stresses. These failures often develop gradually and can be due to issues like material degradation, operational inefficiencies, or water chemistry problems. Below are the common types of tube failuresRead 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
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
