Abstract

Fossil fuels, coal and gas, accounts by far the basis of electricity generation and will remain playing a key role in the global energy mix. Coal is the most intensive resource use to generate electricity and heat but also use for the industry to produce chemicals and materials. This study proposes four (4) alternatives of electricity generation facility from waste coal-based feedstock, including the analysis of additional portions of another fuels and waste, like coal, urban organic solid waste and biomass, in order to define potential valuable fuels to feed the power generation facilities proposed and improve energy recovery of waste coal. Basically, two (2) processes are selected, combustion and gasification, to recover the energy content on the waste coal-based fuel feedstock. Regarding combustion, pulverised coal and circulating fluidised bed boilers are evaluated, incorporating process units to remove SO2 and CO2 content (post-combustion process), decrease NOx and also produce H2SO4 with high value in the fertiliser manufacturing industry. Regarding gasification, entrained-flow gasifier integrated in a combined cycle is selected (IGCC), incorporating process units to concentrate sulphur compounds and CO2, increase H2 production, remove H2S and CO2 content (pre-combustion process), and decrease NOx compounds. The conceptual design models are defined through the integration of different units and deployment of available technology. The evaluation of the conceptual basic design according to the power output set for a maximum waste coal or sterile contribution, establishes that rates over 95% H2S and 90% CO2 removal can be achieved. The conceptual design of the different units, the assessment and evaluation of the different configurations, will come in useful, supporting decision-making groups to select the most convenient form of using waste coal, coal and other types of organic waste, to mainly produce electricity with no emission, especially greenhouse gas emission, acid gases like carbon dioxide and sulphur compounds.
