Water Handbook - Boiler System Failures | SUEZ

Departure from nucleate boiling (DNB) occurs when the bubbles of steam forming on the hot tube surface begin to interfere with the flow of water to the inside tube surface, and eventually coalesce to form a film of superheated steam over part or all of the heating surface. Consequently, the tube wall may be subjected to local overheating and eventual rupture. Ribbed tubing was developed to inhibit the …
