A Study On Design Optimization Of Direct-Fired Sco2 Combustors

Abstract

This work provides optimized guidelines for the development of direct-fired sCO2 combustors. The combustor is modelled by coupling perfectly stirred reactor (PSR) and plug flow reactor (PFR) models with real-gas chemistry. The high pressure Aramco 2.0 mechanism is used to estimate the kinetic behavior of sCO2 combustion under various operating conditions. Initially, the feasible CO2 dilution levels in the primary zone and corresponding inlet temperatures are investigated for the design of sCO2 combustor. The results show that the high temperature conditions such as, 1000 K under 45% CO2 dilution level, and all temperature conditions under 30% CO2 dilution level are practically possible for sCO2 combustor design.
