Combustion Experiments On A Solid Fuel With Low Sulphur Content

Grate Furnace Combustion: A Submodel for the Solid Fuel Layer

The reduction of NOx-formation in biomass fired grate furnaces requires the development of numerical models. To represent the variety in scales and physical processes playing a role in the conversion, newly developed submodels are required. Here, a submodel for the reverse combustion process in the solid fuel layer on the grate is described. The submodel is shown to give good predictions for th...

Effects of nitrogen content in fuel on NOX emissions under oxy-fuel coal combustion

Oxy-fuel coal combustion with flue gas re-circulation is known to be one of the most promising methods for reducing CO2 emissions from coal combustion power plants. In the oxy-fuel system, the combustion atmosphere consists of only O2 separated from air and flue gas re-circulated from a stack. Therefore, the flue gas is dominated by CO2 without any nitrogen gas. The most attractive potential as...

Biomass Characterization and its Use as Solid Fuel for Combustion

(Received: January 8, 2012; Accepted: Februray 8, 2012) Abstract: The power industry is confronting challenges with seemingly conflicting goals. They provide the economy of scale needed to minimize the cost of production. Consumers, including industry, rely on affordable, dependable electrical energy. It’s an important part of our economy and our daily lifestyle. However, reducing emission leve...

Sulfur Release from Cement Raw Materials during Solid Fuel Combustion

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...
