Combustion of Fuels - Carbon Dioxide Emission

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]

Carbon Dioxide Separation from Flue Gases: A Technological

CO 2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in recent decade (26 to 30 percent of all CO 2 emissions). Main anthropogenic emissions of CO 2 come from the combustion of fossil fuels. CO 2 concentration in flue gases depends on the fuel such as coal (1215 mol-% CO 2) and natural gas (3-4 mol-% CO 2).

Oxyfuel Combustion - an overview | ScienceDirect Topics

The flue gas with a high concentration of CO 2 discharged from the tail of the boiler is purified by a flue gas cleaning system (FGCD) and then enters the compression and purification unit (CPU) to obtain high purity liquid CO 2 for transportation, utilization, and storage.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Miscanthus x giganteus - Wikipedia

Miscanthus × giganteus, the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of more than 4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.

CHAPTER 3 COMBUSTION CALCULATION

CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC. The flue gas leaves the boiler at 300oC (all the water formed will be vapour). In addition, a substantial amount of heat is also lost through the boiler wall and other uncounted sources.

The fan sucks the flue gas from the furnace creating a partial vacuum inside the furnace. Thus atmospheric air is induced to flow through the furnace to aid the combustion of fuel. The flue gases drawn by the fan passes through chimney, to the atmosphere.

A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.
