Read MorePart of the extracted steam is used to heat the feedwater in an open feedwater heater. The rest of the extracted steam is used for process heating, and leaves the process heater as a saturated liquid at 1.6 MPa. It is subsequently mixed with the feedwater leaving the feedwater heater, and then the mixture is pumped to the boiler pressure. Determine

Read MoreSep 19, 2014 · The microhardness of the coating ranges from 6.2 to 9.5 GPa, with an average value of 8.0 ± 1.6 GPa. This value is about 10 times that of the boiler tube AISI 1020 steel. The hardness values are quite narrowly scattered, which can be attributed to the low porosity of the coating.
