CFD Analysis of Temperature Imbalance in Full Scale

Tangentially fired boilers are widely used in generating electricity power due to its advantage of distributing heat evenly to all furnace walls. However, this type of boiler poses common temperature deviation at the upper furnace which may lead to temperature imbalance. This consequently may reduce the performance of the boiler which cannot be simply ignored.

Numerical Modelling of Pulverised Coal Combustion

Abstract. Many thermal power generation plants rely on combustion of pulverised coal carried out in large furnaces.
