• Observation Equipment • Flow Indicators • Pressure Vessels/TanksTempering. Tempering greatly increases the strength of glass and helps it overcome the damaging effect of scratches and other surface defects. Glass is heated to a specified point above its annealing temperature, then quickly quenched causing the surface to shrink and harden.
A high pressure boiler plant of 51 to 500 horsepower is exempt from the high pressure attendance requirements of item A if the plant is operated at low pressure. All boilers must either be shut down or shifted to low pressure. If a boiler is shifted to low pressure, it must have the following controls, safety devices, and conditions: §
Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.

Step 1 - Pressure. Boiler pressure builds up in the system. The way to reduce it is to bleed the system by letting air escape. The boiler feeds a closed circulation system. By expressing air from the system you reduce the pressure in the system. You can then adjust the pressure level later by turning on the feed of cold water to the system.
