Recovery boiler - Wikipedia

2019-6-29 · 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 480 o C. The pressures and temperatures used then backed downward somewhat due to safety.

Corrosion in boilers - Lenntech

Corrosion is caused principally by complex oxide-slag with low melting points. High temperature corrosion can proceed only if the corroding deposit is in the liquid phase and the liquid is in direct contact with the metal. Deposits also promote the transport of oxygen to the metal surface.
