System and Process for Combusting Coal and Beneficiated Organic-Carbon-Containing Feedstock

A coal combustion process for combusting coal and processed biomass in a coal combusting apparatus with less adverse by-products, comprising the steps:

• providing coal feedstock to a first chamber of the coal combusting apparatus, the first chamber configured to pulverize coal and feed the coal into the coal combusting apparatus in a first concentration of feedstock,
• making a processed biomass pellet feedstock in a processed biomass system, comprising the steps of:
• a. inputting into the processed biomass a system comprising a first and a second subsystem an unprocessed organic-carbon-containing feedstock that includes free water, intercellular water, intracellular water, intracellular water-soluble salts, and at least some plant cells comprising cell walls that include lignin, hemicellulose, and microfibrils within fibrils;
• b. passing unprocessed organic-carbon-containing feedstock through the first subsystem, a beneficiation sub-system via a beneficiation sub-system process, to result in processed organic-carbon-containing feedstock with characteristics that include having an energy density of at least 17 MMBTU/ton (20 GJ/MT), a water content of less than 20 wt %, and a water-soluble intracellular salt content that is decreased more than 60 wt % on a dry basis from that of the unprocessed organic-carbon-containing feedstock;
• and
• c. passing the processed organic-carbon-containing feedstock through the second subsystem, a pelletizing sub-system via a pelletizing sub-system process, to result in processed biomass pellets;
• providing processed biomass pellet feedstock to a second chamber of the coal combusting apparatus, the second chamber configured to pulverize the processed biomass and feed the processed biomass into the coal combusting apparatus in a second concentration of feedstock with the ratio of the first concentration to the second concentration between 1 to 9 and 9 to 1;
• passing a gaseous waste stream of the coal combustion apparatus through at least one exhaust chamber comprising at least one gas separation sub-system configured to separate at least 50 volume % of carbon dioxide from the gaseous waste stream and create separated carbon dioxide;
• and
• passing the separated carbon dioxide through a gas consumption sub-system configured to receive the separated carbon dioxide gas and consume it in the making of useful materials.
