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
What steps precede internal inspection of boilers
Before conducting an internal inspection of boilers, several important preparatory steps need to be taken to ensure safety and thoroughness: 1. Isolation and Shutdown: Safely isolate the boiler from the rest of the system and shut down the boiler, including all fuel and ignition sources. 2. Cooling Period: Allow theRead More
