The … Web• Carried out dimensional inspection on all the finished products like Steam Drums and HRSG Modules, and other boiler auxiliaries as economizer ,evaporator and super heater modules • Coordination with Inspection personnel, …
WebLet us refine the representation in the enthalpy chart (figure below) . The bold line represents, between points 1 and 2, the cooling of the effluent, from Tmax, maximum temperature, to Trej, exhaust temperature, and … WebMar 15, 2006 · Similar arrangements are used for HRSG components such as evaporators and economizers. But these components exhibit fewer thermal-transient problems because the water they contain absorbs …
WebSep 16, 2024 · HRSG is in principle as a pressurized steam maker, with heat media coming from gas turbine exhaust gas. Then the steam turbine and then rotate using the exhaust … WebApr 10, 2024 · The predicted performance of the HRSG expects the use of a three element drum level control system in the evaporator. This will allow a smooth control in the drum tank dynamic behavior. The configuration is based upon three process variables that are measured during the HRSG operation: output steam flow, drum liquid level and …
WebThe evaporator pressure should preferably be positive, i.e. above atmosphere pressure, to prevent the leakage of air and moisture into the refrigeration system. Table 17-1 shows evaporator pressure at −15°C (258 K) and condenser pressure at 29°C (302 K) for several refrigerants [2]. Table 17-1.
