2013-9-18 · ST.37.8, to DIN 17177. The normal test pressure of the tube is 40 bar and the coil is stress-relieved at 600 0C. The number of sections used is dependant on the heat output requirements of the boiler. The staggered (zigzag) configuration of the pancakes, one above the other, improves heat transfer from the exhaust gases to the tubes.

Thermoeconomic Analysis of a One-Pressure Leve

Using Roosen et al. correlation the pressure that minimize COE is about 25bar. This value is smaller than the thermodynamic optimum pressure (28 bar) because when the pressure rises, the heat recovery steam generator HRSG cost grow down, too. Thus, the power plant is little less efficient, but also the capital cost is smaller.

Waste Heat Recovery Research Papers - Academia.e

In this paper, we analysed the relation between heat transfer rate and entropy generation for single pressure and dual pressure waste heat recovery boiler. The entropy generation per heat transfer is less in dual pressure boilers than in single pressure boilers because the temperature difference of heat transfer is less in dual pressure boilers

Condensate Recovery - beta.spiraxsarco.c

If the return line were connected to a vessel at a pressure of 1 bar g, then it could be seen from steam tables that the maximum heat in the condensate at the trap discharge would be 505 kJ/kg and the enthalpy of evaporation at 1 bar g would be 2201 kJ/kg. within the boiler. Continuous blowdown lends itself to the recovery of the heat
