Injection of coal and waste plastics in blast furnaces
The majority of waste plastics currently produced are either landfilled or incinerated. Plastics do not readily degrade and toxic elements can be leached from the landfill. Combustion of waste plastics can generate environmentally hazardous air pollutants such as dioxins/furans, as well as undesirable carbon dioxide. Consequently, cost effective ways of recycling the increasing amounts of gener...
متن کاملBlast Furnace Coal Injection Trial Results Using Granulated and Pulverized High Volatile Coal
INTRODUCTION This report presents the results of two trials conducted with the Blast Furnace Granular Coal Injection System at Bethlehem Steel Corporation's Bums Harbor Plant. The trials were conducted using granulated and pulverized high volatile coal from Colorado. The first trial was conducted to quantify the effect that a high volatile western coal, Colorado Oxbow, has on the blast furnace ...
متن کاملStudying Peak Particle Velocity Due to Blast in Development Tunnels’ Face in Coal Stoping
The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of the development tunnel face to the stope face. Also, the quality of the rock mass wherein the whole stope face is located might pose considerable...
متن کاملOxyfuel combustion: technical and economic considerations for the development of carbon capture from pulverized coal power plants
avoidance cost of carbon capture from pulverized coal plants. To investigate this possibility, a technoeconomic oxyfuel model was constructed. The model was exercised to explore the effect on CO2 avoidance cost and LCOE from several key parameters, namely: CO2 purity, oxidant purity, CPU and ASU performance and cost, coal composition, and geographic location. Monte-Carlo techniques were then us...
متن کاملModeling Soot Derived from Pulverized Coal
A semiempirical model has been developed for predicting coal-derived soot. The main feature of the model is a transport equation for soot mass fraction. Tar prediction options include either an empirical or a transport equation approach, which directly impacts the source term for soot formation. Also, the number of soot particles per unit mass of gas may be calculated using either a transport e...
