Cold gas efficiency definition

WebHigh operating temperature and pressure (up to 5 MPa) in the case of EFGs leads to higher throughput in comparison with other types of gasifiers; however, the thermal efficiency is quite lesser because the produced syngas needs to be cool down to a greater extent before used for the applications. WebTo sustain fluidization, or suspension of coal particles within the gasifier, coal of small particles sizes (<6 mm) is normally used. Coal enters at the side of the reactor, while steam and oxidant enter near the …
