Feedstock flexibility could include, but is not limited to: 1) ability to accept variations in composition of the design coal feedstock, 2) ability to utilize different types/ranks of coals or coal wastes, 3) ability to co-feed coal with a non-coal feedstock such as natural gas, biomass or wastes from petroleum-based synthetic materials (e.g ...
How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

· Despite Pledges to Cut Emissions, China Goes on a Coal Spree. China is building large numbers of coal-fired power plants to drive its post-pandemic economy. The government has promised a CO2 emissions peak by 2030, but the new coal binge jeopardizes both China''s decarbonization plans and global efforts to tackle climate change.
The coal feed particle size (~ 1–3 mm) is smaller than fixed-bed gasifiers (10–50 mm), but significantly larger than entrained flow gasifiers (< 200 μm), and the temperatures of operation are lower than entrained flow gasifiers, typically 850–900 °C. This low temperature is required to ensure that the mineral matter in the feed remains ...
