Get Price And Support Online; Integrated Gasification Combined Cycle IGCC. How does Integrated Gasification Combined Cycle . Coal is combined with oxygen in the gasifier to produce .
الحصول على السعرThe production of each of these gases is shown in Figure 1. Coal is first crushed and sometimes dried, then fed into gasifier, in which coal reacts with steam and either air or oxygen. The gasification reaction usually occurs at high temperatures from 800 to 1900°C and high pressure up to 10 MPa.
الحصول على السعرGASIFICATION CHAMBER. UCG Process. UCG operation is initiated by drilling two adjacent boreholes into the coal seam and injecting pressurised oxidants like hot air, oxygen or steam into the coal seam, igniting the coal seam and recovering the combustion gasses through the adjacent borehole.
الحصول على السعرCoal is gasified typically at a pressure of around 30 bar (a) in the presence of high pressure steam and pure oxygen to produce a gas suitable for a variety of applications. This technology is a reliable, mature and robust gasification technology with proven commercial success.
