Assessment of the Superheater Ash Fouling Using a Numerical Model of the Superheater

Heat Transfer Engineering, 2018
Superheaters are high-temperature cross-flow heat exchangers. Steam flows inside the tubes, and the flue gas outside in a direction perpendicular to the axes of the tubes. However, they differ very substantially from the other heat exchangers operating at low temperatures.

On the Limit of Superheat

Journal of Applied Physics, 1958
A new method of observing the limit of superheat was devised, in which small drops of a sample liquid are heated as they rise up in the non-soluble heating liquid with a suitable temperature gradient upward. Using the method, the limit of superheat was determined, mainly for some saturated hydrocarbons and polymethylenes.

Superheater Components

2019
Abstract Some examples of equipment failures involving high temperature operation are presented. They include some steam generator superheater components and a pump shaft that should not have been at high temperature. Metallographic analysis is used to determine the causes of failure in each case.

Modeling of Superheater Operation in a Steam Boiler

Volume 1: Fuels and Combustion, Material Handling, Emissions; Steam Generators; Heat Exchangers and Cooling Systems; Turbines, Generators and Auxiliaries; Plant Operations and Maintenance; Reliability, Availability and Maintainability (RAM); Plant Systems, Structures, Components and Materials Issues, 2014
A numerical method for modeling actual steam superheaters is presented. The finite volume method was used to determine flue gas, tube wall and steam temperature. The numerical technique presented in the paper can especially be used for modeling boiler superheaters with a complex tube arrangement when detail information on the tube wall temperature ...
