The steam generator often goes out

Water Handbook - Boiler System Failures | SUEZ

Superheater tubes often show the same swelling or enlargement effect. In such instances, steam flow has been restricted for some reason, leading to overheating and eventually to failure. Acidic Attack. Acid attack of boiler tubes and drums is usually in the form of general thinning of all surfaces. This results in a visually irregular surface

The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In large utility boilers water-filled tubes form the walls of the furnace to generate steam and saturated steam coming out of the boiler drum re-enter the furnace through a superheater to become superheated.

Common Steam Boiler Problems & How to Troubleshoot Repairs

Corrosion can transpire anywhere in the boiler. In fact, this boiler problem often happens starting on the inside and eventually works its way out. Therefore, signs of corrosion may not be evident until a pipe or tank leaks. Typically, corrosion stems from a chemical reaction of …

Boiler blowdown - Wikipedia

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of
