概要

• 論文の詳細を見る

• The influences of coal properties and combustion conditions on the unburned carbon content in flyash from the modern pulverized-coal-fired boiler were predicted numerically through a one-dimensional model, in which the profiles of temperature and air-fuel ratio in the furnace were predetermined. The main factors inestigated are the percentage of two stage combustion, furnace length, heat liberation rate in the furnace, exhaust gas recirculation and fuel properties. Predicted results give useful information to reduce unburned carbon in flyash.
