High Temperature and Pressure Recovery Boiler
Development of recovery boiler main steam pressure and temperature was rapid at the beginning. By 1955, not even 20 years from birth of recovery boiler highest steam pressures were 10.0 MPa and 480oC. The pressures and temperatures used then backed downward somewhat due to safety. By 1980 there were about 700 recovery boilers in the world.

Famous quotes containing the words high, temperature, pressure and/or recovery:
“Like other high subjects, the Law gives no ground to common sense.”
—Mason Cooley (b. 1927)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
“Much of the pressure contemporary parents feel with respect to dressing children in designer clothes, teaching young children academics, and giving them instruction in sports derives directly from our need to use our children to impress others with our economic surplus. We find “good” rather than real reasons for letting our children go along with the crowd.”
—David Elkind (20th century)
“It’s even pleasant to be sick when you know that there are people who await your recovery as they might await a holiday.”
—Anton Pavlovich Chekhov (1860–1904)
