ANALYSIS ON THE THERMODYNAMIC CALCULATION FOR 200 MW BOILER AT DOUHE POWER PLANT[J]. Thermal power generation, 2001, (1): 18-21. DOI: 10.19666/j.rlfd.2001.01.006.
A thermodynamic calculation had been carried out in Douhe Power Plant for HG 670/140-9 type boiler which hadn’t been retrofitted.Compared with the original calculation in design provided form Harbin Boiler Works
it was modified in three aspects:adopting thermodynamic calculation standard promulgated in 1973 by former Soviet Union
applying Dubskploh gas temperature calculation formula at furnace outlet
and using actually measured data of Δx
In such case
the calculation result is comparatively in conformity with the real operation status.The result has been compared with original calculation in design
and the reasons leading to over-temperature of superheated steam and insufficient temperature of reheated steam
