The Integrated Steel Plant, initially envisaged as the country's first steel plant to be based on purely swadeshi raw material, involved setting up world's largest Coal Gasification Plant (CGP) for Steelmaking through the DRI route.
16.1.2. Coal gasification for power generation. Integrated Gasification Combined Cycle (IGCC) uses syngas from gasification of coal (or mixtures of coal with biomass or other hydrocarbon materials such as petroleum coke), and integrates this with a combined-cycle steam and gas turbine system for electricity generation.
The gasifier is coal-water slurry fed, oxygen-blown, refractory-lined gasifier with continuous slag removal system and dry particulate removal. The process is good …
Underground Coal Gasification. Underground coal gasification (UCG) is just an industrialised gasification process that takes place in coal seams that haven't been mined. It entails injecting a gaseous oxidising agent, often oxygen or air, and transporting the resultant product gas to the surface via production gas wells drilled from the surface.
The report will cover applications of modelling in various gasifier types such as entrained flow, fluidised bed and moving bed gasifiers as well as in commercial processes such …

Most of the entrained flow gasifiers can be operationally classified into the following categories, as also shown in Table 1: 1. Dry fed versus slurry fed: The MHI, Siemens, Shell, and PRENFLO gasifiers use dry feeding of powdered coal, whereas the GE, E-Gas, ECUST, and Tsinghua OSEF gasifiers operate on coal-water slurry (CWS) …
Gasification of biomass is a thermochemical process in which solid biomass is treated with a limited amount of gasifying medium to convert it into valuable gases such as Methane (CH 4), Carbon Dioxide (CO 2), Carbon Monoxide (CO), and Hydrogen (H 2) and a solid residue named char.The gases can be further converted to liquid fuels via …
