CB&I E-GAS™ Gasifiers netl.doe.gov

The E-Gas™ coal gasifier is a pressurized, upflow, entrained slagging design with a unique two-stage operation. Like the GE gasifier, E-Gas™ is a slurry-feed gasifier. Wet crushers produce slurries from the raw feed coal. Coal slurry concentrations typically range from 50 to 70% depending on the inherent moisture and quality of the feed coal.

Utilization of Coal Gasification Slag Collected from IGCC

2.2 Features of EG slag The slag that has flowed from the coal gasification unit is water-cooled in the slag cooling unit, passes through the slag crusher and is collected within the slag rock hopper. The slag rock hopper has a mechanism that allows for the discharge of the slag under normal pressure from the under-high-pressure EAGLE furnace.

Shell Coal Gasification Process an overview

The Shell coal gasification process (SCGP) uses an up flow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. 8.5).The up flow arrangement allows separation of syngas and slag largely within the reactor itself. Typically, there are four side mounted burners located in the lower part of the reactor. The vessel containment uses a membrane wall, which has a

4.2. Major Gasification Solid Byproducts netl.doe.gov

Slag and Ash As discussed in the Background, solid waste from conventional pulverized coal-fired power plants is a significant environmental issue due to the large quantities produced, chiefly of coal fly ash, and the potential for leaching of toxic substances (e.g. heavy metals such as lead and arsenic) into the soil and groundwater at disposal sites, and accidental releases from coal ash ponds.

Kinetics of CO2/Coal Gasification in Molten Blast Furnace Slag

Nov 26, 2012· The coal/CO2 gasification reactions in molten BF (blast furnace) slag were studied kinetically by temperature-programmed thermogravimetry using a thermal analyzer. The effect of heating rates and molten BF slag on coal gasification were studied, and the activation energies, frequency factors, and most possibility mechanism functions were calculated. The results show that the order of

New Slag–Char Interaction Mode in the Later Stage of High

In this work, characteristics of single brown coal char particle gasification at around the ash fusion temperature was investigated. The particle size of gasification residue decreased with the increase of reaction temperature and the ultimate conversion of coal char increased with the reaction temperature. The SEM-EDS analysis was carried out to investigate the microstructure characteristics

Gasification Wikipedia

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in
