Introduction. Steam cycles have been used for electric power generation from coal since the early 1900's. These first coalfired power units featured outputs in the range 110 MW and the steam generator already included an economizer, an evaporator, and a superheater (Harvey et al., 2020).According to the same reference, the first steam cycle had an efficiency of only % while those ...

Steam quality Steam quality is defined as the percentage of steam in the vapor phase. Poor steam quality (about 80% vapor) will decrease the conditioning temperature needed for 1% added moisture by about 5°F. Higher vapor steam, about 97% vapor, means higher quality steam. Steam quality is preserved by condensation traps that remove
