Mathematical Modeling and Experimental Study o

2008-2-23·Grate boilers are widely used to fire biomass for heat and power production. However, grate-firing systems are often reported to have relatively high unburnout, low efficiency, and high emissions and need to be optimized and modernized. This paper presents the efforts toward a reliable baseline computational fluid dynamics (CFD) model for an industrial biomass-fired grate boiler, which can be

A mathematical model of a 200 MW boiler

2018-6-4·Abstract A mathematical model is developed for a 200 MW coal-fired, drum-type natural circulation boiler with reheat. The complete unit is divided, for the convenience of the analysis, into several sections, viz. the economizer, the drum, the downcomer, etc. The dynamic behaviour of each section is described in mathematical terms. The equations are linearized and manipulated into state
