Model H.E. Steam Boilers

Reheater safety valves prevent excess pressure in the reheater. When the valve opens, the hot reheater steam is blown off via the connected rising pipe and attached silencer through the roof into the atmosphere. The valves thus interrupt the otherwise closed water-steam cycle. Unlike the HP/IP/LP bypass valves, there is no steam cooling.
