This paper investigates the failure of superheater tubes, made of AISI 304 stainless steel, after 10 years of service in a power plant. The failure is in the form of fish mouth rupture and is mostly observed at U-bent elbows. Microstructure of the degraded samples was analyzed using optical and scanning electron microscopes. Phases were …

LPG / PROPANE POWER GENERATION. Liquefied Petroleum Gas (LPG, Propane) is fast becoming the fuel of choice for power generation in rural and other remote, off-grid locations, in lieu of its less environmentally friendly counterparts such as diesel, coal and fuel oil. For decentralized, distributed power generation models and combined heat and ...

Inspection of each piece of equipment is required as part of a power plant-reliability program. Detailed procedures and assessments are developed based on standard or best practices in the power industry. For an accurate assessment, an understanding of the damage mechanism is crucial. In this work, a study was conducted on a …

As superheater header is exposed to high pressure and temperature in power plant boilers, it is one of the most sensitive parts in a power plant.Cracks may form where tubes and main steam outlet (nozzle) are connected to reservoir. This article examines a quarter-circle crack at the corner of a nozzle junction and its propagation …

This study focuses on the optimal design of future-generation primary superheaters for a fast load-following operation. To achieve this, a detailed first …

Superheaters and Reheaters. Superheaters are one of the most important accessories of boiler that improves the thermal efficiency. In super heaters there should not be any fins as it increases the thermal stresses and carful should be taken when choosing the super-heater material that is stand for high temp and corrosion resistance.

Hence, the economiser in thermal power plants, is used to economise the process of electrical power generation, as the name of the device is suggestive of.The recovered heat is in turn used to preheat the boiler feed water, that will eventually be converted to super-heated steam.Thus, saving on fuel consumption and economising …

Abstract. A model based on a concept of "fraction of exfoliated area" as a function of oxide scale strain energy was developed to predict the extent of exfoliation of steam-side scale from boiler tube superheater loops. As compared with the Armitt diagram, which can be used to predict when scale damage and exfoliation would be likely to …
