WSN series gas / oil fired industrial horizontal steam boiler is a kind of safety and high efficiency heating equipment with fully automatic intelligent control system. It’s a boiler shell type 3 passes wetback oil/gas fired boiler. Usually, the WNS series steam boilers widely used for industry production and processing, such as textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc.

Superheater and Reheater (SH and RH)

Lower tube thickness is permitted because the fins help to add to the strength of the tube. Also since the HRSGs experience no erosion or corrosion, the sacrificial material for such effects can be saved. Superheater and reheater tubes in conventional boilers are nearly always plain tubes to facilitate cleaning and avoid fouling.

Failure Analysis of Superheater Tu

2017-9-7 · The failure analysis of a ruptured superheater tube after 20 years service in the oil-fueled boiler, as the typical problems in power plants, was investigated. A thin-lipped rupture at failed region was observed in superheater tube. By measuring the tube's wall thicknesses far from failed region, non-uniformity was seen.

Failure analysis of high temperature superheater tube

The boiler tubes used by Manjung Power Station are classified as high temperature superheater (HTS) tubes. Table 2 shows the details and operating conditions of high temperature superheater tube. The material used for this HTS tube is A213-T91 which is similar to modified 9Cr-1Mo steel.

Superheater Tube From Boiler - Metallurgical

Metallurgical Technologies, Inc. examined a failed superheater tube from XXXXXX X XXX Boiler #7. The ASME SA-213 Grade T11 tube had been in service for 6 to 8 years until failure. The mode of failure was short-term stress rupture due to significant overheating.

Boiler superheater tubes in secondary creep stage -

2006-11-13 · Typically, steam circuit boiler tubing should be monitored every 5 years or sooner (if, tube failures begin to occur). We have Cr-Mo superheater and reheater tube circuits along with low temperature primary superheater carbon steel tubes that have accumulated over 300,000 operating hours, and are still going strong.

Engineer's Guide to Boiler Tube Inspections

Engineer's Guide to Boiler Tube Inspections is often the first to observe issues such as increasing boiler make-up water levels or the characteristic sounds of superheater or reheater tube leaks. Occasionally, tube leaks can be seen via boiler observation ports or high-temperature thermography cameras. is the most widespread and

Failure Analysis Study of a Cracked Superheater Outlet

2018-2-2 · boiler. In September of 1992, Unit 1 was forced out of service due to a failed terminal tube on the East radiant superheater outlet header. This was the first known creep related terminal tube failure on Unit 1. During this forced outage, more bulged and swollen tubes were discovered. In addition, several minor cracks in the tube
