CFD Approach for Unburned Carbon Reduction in Pulverized
· Low-NOx technologies are widely used in pulverized coal boilers but they usually produce high levels of carbon in the fly ash. High levels of unburned carbon represent fuel loss so the overall boiler efficiency is reduced. Additionally the higher carbon content affects the suitability of fly ash for cement applications. The purpose of this paper is to provide a CFD approach for unburned

The Hidden Costs of Wind PowerIER
· Thus the full cost of wind power is 140 percent higher than an advanced natural gas-fired plant and over 70 percent higher than an advanced coal or nuclear plant. Thus assertions made by the wind industry that wind power is becoming cost competitive with fossil fuel-generated power are not the case from these cost estimates.
