Jan 25, 2008 · The terms "boiler shock" and "thermal shock" describe a type of heat-stress in greenhouse boilers that can lead to damage and serious structural failure of the boiler vessel. Boiler shock, in essence, is caused when cold water is pumped back into a hot boiler.
Hydraulic Shock Absorbers. All hydraulic shock absorbers work by the principle of converting kinetic energy (movement) into thermic energy (heat). For that purpose, fluid in the shock absorber is forced to flow through restricted outlets and valve systems, thus generating hydraulic resistance. A telescopic shock absorber (damper) can be compressed and extended; the so called bump stroke and rebound stroke.Telescopic shock absorbers …

Boiler feedwater being introduced into the steam drum. Cooler water sinking through tubes called "downcomers." Water absorbing heat from the tubes, then the heated water rising to the steam drum. Due to the critical need for water, modern boilers are equipped with automatic low-water trip switches.
Mar 21, 2019 · Thermal shock occurs when cold water enters a hot boiler. When a boiler is running at or near full power, it is full of boiling water, so the sudden introduction of cold water will cause a serious reaction with the hot water currently in the boiler. This potentially powerful reaction is called thermal shock.
