Mar 21, 2018 · In case of water tube boilers, hot gases will provide the required temperature to produce superheated steam and superheater may be an additional part of the furnace area. In other cases, separately fired superheater may be required because gas turbine produced gases are relatively cool.
The SuperHeater Overheat Protection (SHOP) system is a proprietary technology that helps mitigate the risk of superheater tube failure due to short-term overheat during boiler start-ups. SHOP assists operators in the management of boiler start-ups by enabling the detection of superheater tube clear events (TCE’s).
The boiler tubes are under high pressure and/or high-temperature conditions. They are subject to potential degradation by a variety of mechanical and thermal stresses and environmental attack on both the fluid and fireside. Mechanical components can fail due to creep, fatigue, erosion, and corrosion
For example, in a super-heater of SA192 tubes, with a designed metal temperature of 800 o F, the ASME Boiler and Pressure Vessel Code gives the allowable stress at 800 o F as 9,000 psi. If the tube-metal temperature should rise to a temperature of around 1300 o F, the hoop stress would be equal to or slightly greater than the tensile strength at 1300 o F, and failure would occur in a few minutes.

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
Nov 22, 2019 · In steam automobiles and power plant boilers alike, the superheater tubes — sometimes known as vaporizer coils — were located directly on top of the burner. Steam usually is run through the superheater after it has been admitted through the throttle. Convection superheaters are most commonly found on locomotives.
