A mathematical model of a 200 MW boiler:

2007-3-27 · 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

System Identification and Controller Design for Boiler

Mathematical modeling of Boiler and heat exchanger set-up is done by System Identification method. System Identification method is better option to predict mathematical model of a complex system as well as it takes much less time to estimate a model than first principle method.

A mathematical model of slagging of the furnace of

Abstract. The mathematical model of furnace slagging integrated into the Sigma-Flow program system of computational hydrodynamics has been developed; this system makes it possible to calculate aerodynamics, processes of heat-and-mass exchange, and combustion processes in complex technological facilities, including pulverized-coal-firing furnaces.

Mathematical model of a supercritical power boiler for

The developed mathematical model of the boiler considers the fact that three heating surfaces (namely, the steam superheater or economizer coils, wall steam superheater SH1, and hanger tubes) are located in parallel in the flue gas duct. All the heating surfaces are modelled using detailed data obtained from the Polish boiler manufacturer.

2008-2-23 · A baseline model is then defined on the basis of the sensitivity analysis and the measurements. The baseline results show an overall acceptable agreement with the measured data and the site observations, indicating that the baseline model is applicable in the optimization of the boiler and the design of new grate boilers.

A Mathematical Model of Biomass Briquette Fuel

2014-3-6 · The numerical simulation model is proposed according to the characteristics of the biomass briquette fuels, which involves two main areas of interest: the solid combustion model in the bed and the out-of-bed gas combustion model. The contents and characteristics of 3 kinds of biomass and coals were experimentally tested. The biomass fuels compared with the coal fuel have the following
