Computational modeling of pulverized coal fired boilers

Jan 15, 2019 Computational modeling of pulverized coal fired boilers has made considerable advances in the past 5 decades. Modeling the furnace of a coal-fired boiler is a complex task. Even though bulk of the heat transfer to the furnace water walls is by radiation, it is complicated by the presence of ash and other tri-atomic gases that participate in

Modeling of Pulverized Coal Combustion in Cement Rotary

In this paper, based on analysis of the chemical and physical processes of clinker formation, a heat flux function was introduced to take account of the thermal effect of clinker formation. Combining the models of gas−solid flow, heat and mass transfer, and pulverized coal combustion, a set of mathematical models for a full-scale cement rotary kiln were established.

Modeling Soot Derived from Pulverized Coal Energy & Fuels

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

Measurements and CFD modeling of a pulverized coal flame

Mar 01, 2016 Measurements of fly ash deposition in a 15 kW pulverized coal jet flame and CFD-based mathematical modeling have been performed. The deposits have been collected at two ports at particle Stokes numbers in the 0.02–0.34 range and particle kinetic energies not larger than 2 × 10-9 J. Inertial impaction and thermophoresis have been identified as main mechanisms of particle transport towards

A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel, with abrasion-resistant alloy fan blades, transports the pulverized coal from the pulverizer section through the coal pipes to the burners. A typical arrangement of an ATRITA pulverizer system is shown in Figure 3.
