...DISCUSSION The damage mechanisms observed for the Ni-P coating in the non-aerated saturated 160 °C steam and the 10% wet low pressure steam included corrosion of the external surface and penetration of the coating at internal microdefects and microcracks. There was no expansion of the formed...

...During the past, there had been some silencer incidents with catastrophic consequences from using a less-than-optimal design in an industrial steam silencer. One example, the steam jet hit the head of the diffuser with sonic speed and high temperature. This not only destroyed the diffuser, but also...

Hydrogen Hydrogen Analysis Corrosion Magnetite Passivation Boiler Steam Condensate Monitoring FAC (Flow Assisted Corrosion) UDC (Under Deposit Corrosion) INTRODUCTION Hydrogen analysis has been...

...Close internal inspection was performed at steam header and cluster pitting exactly like tube corrosion was detected. Inspection was performed after two years at same line. Corrosion was compared together which shows exactly the same mechanism of corrosion while corrosion rate was extended (Compare...

...Abstract Volatile filming corrosion inhibitors are increasingly utilized in industrial, utility and commercial boiler systems to control corrosion of low carbon steel and copper alloys throughout the steam-water cycle. This paper presents a novel approach for combining volatile filming technology...

... these laboratory tests were successful in outlining the basic mechanism for metal dusting, predictions about alloy resistance based on these academic studies have not proven to be accurate for all plant conditions. Multiple papers published at NACE and elsewhere have pointed to the important role that steam can...

...Abstract Ni-base alloys are of increasing technological interest for advanced power generation concepts including ultrasupercritical steam and supercritical carbon dioxide (sCO₂) as well as their traditional role in gas turbines. For applications at 650°-800°C, commercial precipitation...

...Abstract One future objective is to develop advanced ultrasupercritical coal-fired boilers that incorporate oxy-firing to facilitate carbon capture. The steam condition goals of 760°C/34.5 MPa will require major materials changes throughout the boiler, including Ni-base alloys in the hottest...

...-forming stainless steels and even Ni-base alloys. To illustrate the oxidation resistance of AFA steel, laboratory exposures are presented in several environments at 550°-900°C including (1) wet air to simulate exhaust gas for thin-walled heat exchangers, (2) steam for power generation applications and (3...

...geothermal power superduplex hydrogen sulphide dissolved oxygen steam INTRODUCTION Abstract Superduplex stainless steel has been used by the oil and gas industry for over twenty years because of its combination of high strength, good ductility and excellent corrosion resistance in sour brines...

... creep strength in softening zone of heat affected zone. On the other hand the creep failure of 9Cr steel tube itself has been reported also. The creep failure is due to the hot spot generated by the obstruction of heat transfer in the part where the steam oxidation scale is exfoliated (not spalling-off...

... coupled plasma analysis and combustion analysis < indicates below the detectability limit of <0.01% bainitic steel high temperature oxidation steam coating CO₂ INTRODUCTION Coal-fired power plants are a major source of CO₂ emissions in the US, especially per MWh...

...Abstract Steam-side oxidation and the resultant exfoliation of iron-based scales cause unplanned shutdowns at coal-fired power generation facilities. Exfoliation mitigation is currently limited to frequent unit cycling to minimize the volume of exfoliated scale and upgrading a plant with a “blow...

... h in steam at 800°C. Application of an aluminide coating protected the alloy from oxidation but decreased the substrate mechanical properties because of the weak coating mechanical properties. Stress was found to have an effect on the Fe-rich oxide grown on alloy T92 during oxidation in wet air...

For one mine, the relative volume flow from these streams is 100 from the recycle pond, 7 from connate, and 5 from utilities, where 0.3 is lost to bitumen and the balance is going to slurry handling to be recycled...

...Abstract The development of a new high efficient power plant generation with higher combustion and steam temperatures demands corrosion resistant steels. The environmental need to establish CO₂ capture technology influences the flue gas composition due to oxyfuel combustion. To conserve...

...Abstract Oxygen scavenger performance is a major consideration in selecting the most favorable chemical treatment program for steam plants. In the last twenty-five years alternatives to hydrazine for oxygen removal in steam generating systems have been introduced. The paper reviews the current...

... of installation of the UNS N07750 bolts, the steam bands were de-commissioned. However, during the subsequent six years of service, some minor joint leakage occurred, which resulted in steam bands around the joint being recommissioned and operated continuously for approximately five years. The precise service...
