As thermal expansion takes place, the pressure builds up to the relief valve's set point, leading to the discharge of a small quantity of water. In case any operating controls fail, causing an overfiring situation, the pressure relief valve will open to discharge steam faster than the boiler can generate it, thus bringing the system's pressure down to a significantly safer level.
