Mathematical Model Of Boiler

Mathematical model of the CFB boiler co-fired with

Abstract: The paper presents a mathematical model of CFB (Circulating Fluidized-Bed) boiler co-fired with power coal, low-grade coal and biomass. The model based on the mass and energy balance equations. Calculation algorithm uses the method included in the European PN-EN-12952-15 Standard (applicable in Poland) and the German DIN 1942 Standard.

Mathematical Modeling of a Biomass Pellet Boiler

2017-12-14 · With a mathematical model emulating the boiler such intensive measurement work could be avoided. The efficiency of a boiler is influenced by its control unit, which regulates the combustion. As the development of new and better control algorithms by measurements take a long time, a model based control improvement should be preferred.

A mathematical model of a 200 MW boiler:

2018-6-4 · 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.

Mathematical model of a supercritical power boiler for

The developed model allows analysing the boiler operation during start-up from cold, warm, and hot states. Moreover, the model allows simulating the boiler operation when the power unit output increases by 7.5% and 5% in a specified period.To satisfy the requirement of increasing the power unit load by 5% in a set period, the live steam mass flow rate must be increased at the boiler outlet.
