The high capital charge has negated the cost benefits associated with using coal as the primary fuel source. The following table provides an approximate breakdown of the cost inputs to produce DRI, utilizing a coal gasification unit as the synthesis gas source.
JSPL started up the country's only coal gasification technology at its Angul plant in January 2020. According to The Hindu BusinessLine, JSPL's managing director VR Sharma said the coal gasification plants will allow the company to use coal while lowering its carbon company's longterm plan is to have 50% of its total steel production via the DRIelectric arc furnace ...
Of total DRI the production in 2008, 74 percent was produced from coal and 26 percent from natural gas. India is now the world's largest producer of DRI. Currently, there are two primary means of DRI production in India: smallscale rotary kilns using coal and iron ore lump, and largelocal scale shaft furnace plants using
Based on the result of the work, the proposed biosyngas DRI route has comparable energy demand compared to other DRI routes, such as the wellestablished coal gasification and natural gas DRI route.

Coal Gasification OptionAn alternative option generating significantinterest in India is the use of a coal gasificationplant in combination with a Direct Reductionplant. The coal gasification plant would uselocal Indian coals to generate a synthesis gas (orsyngas) that can be an acceptable reducing gassource for producing DRI in a shaft furnace.
Steam/coke ratio is an essential parameter in the gasification process to improve the quality of gasification gas (used in the DRI process), and further affects the. Conclusions. A system of lowrank coal pyrolysis coupled with gasification on the basis of pilot test to hydrogenrich gas for direct reduced iron was proposed and modeled.
The gasification reaction supplies the energy required for the metallurgical reactions and for the melting of compacted DRI and coal ash to produce hot metal and slag. The exit gas consists mainly of CO and H 2 at a temperature of 1000 °C, the gas is subsequently cooled and dedusted.
"We are targeting an additional production runrate of million tonnes per year of steel in FY2021 through CGP (coal gasification process) and DRI route," Sharma said.

gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.
Fig. 1 shows that the coal gasification technology route based on concentrated solardriven is comprehensively in line with the global demand for carbon neutrality. This route has a broad prospect and essential strategic value. Thermodynamic analysis of solar catalytic gasification is an important part of the chemical process.
6% in 2000 and nearly 8% in 2019. Global DRI production rose by ~8% to 108 Million tonnes (Mt) in 2019 compared to 2018, representing the fourth consecutive record year for DRI production (see Figure 1). In 2020 DRI production numbers slightly declined due to the COVID19 pandemic, but DRI processes are currently again winning strong support due to

The 75% of DRI or HBI is produced with processes based on natural gas as energy resource, which has to be converted by gas reforming technology to reducing gases (CO and H 2) for the reduction of iron oxide to metallic iron. In the present chapter, the different plant layouts are described.
Jindal Steel and Power Ltd (JSPL) on Tuesday said its coal gasificationbased DRI plant at Angul district in Odisha has resumed operation. "JSPL's MTPA DRI (direct reduced iron) plant based on coal gasification process has resumed operations in Odisha's Angul district," the company said in a filing to BSE. The plant was not operational for long due to the scarcity of coal.
Based on the result of the work, the proposed biosyngas DRI route has comparable energy demand compared to other DRI routes, such as the wellestablished coal gasification and natural gas DRI route. The proposed process can also capture t of CO 2 per t DRI depending on the integration scenarios, which indicates a promising route to ...
The optimization results show that only 3 large centralized coal gasification (CG) hydrogen plants without CCS units are selected (see Table 4). The CG hydrogen plants considered the least expensive feedstock fuel (, coal). Coal is and times cheaper than natural gas and biomass, respectively (see Table 3). In addition, CG plants ...
