Steam blowout

Use vent breaks on high points of syphon. Include high pressure water purge or blowout for pipes with slurries include steam blowout/purge lines for pipes with edible oils, foodstuffs. 

The seawater is acidified with sulfuric acid to a pH of 3.5, 130 g of 100% sulfuric acid being necessary per t of seawater. The slight excess of chlorine necessary to oxidize the bromide is fed in at the same time as the sulfuric acid. The bromine formed is expelled by air in so-called blowout towers. The bromine (and possibly chlorine or bromine chloride)-containing air is fed into absorption towers in which it is brought into contact with a sodium carbonate solution, whereupon the bromine is disproportionated into bromide and bromate according to the above equation. The bromine in the absorption solution is then converted into elemental bromine with sulfuric acid and expelled with steam ...

The opposite problem to steam condensate backup is blowout of uncondensed steam through the reboiler and out the condensate drain line. This phenomenon causes a loss in heat transfer entirely out of proportion to what might be expected. Literally half of a reboiler s duty can be lost by an apparently small amount of steam blowing out the condensate drain line. 

The main condenser is designed to receive and condense the full-load main steamflow exhausted from the main turbine. It also receives discharges from auxiliary systems such as the feed water heater vents and drains and the gland sealing steam spillover and drains. To protect the condenser shells and turbine exhaust hoods from overpressurisation, steam relief blowout diaphragms are provided in the low-pressure turbine exhaust hoods. Two low-pressure feedwater heaters are located in the neck area of each condenser shell, adjacent to where their steam is bled from the low-pressure turbine.
