Grain Drying

The article discusses the VisSim program, which allows simulating microwave grain drying process. Its capabilities and methods of development are shown, the structure of a mathematical model for management of the drying process and individual blocks is provided. It is noted that offered modeling of the grain drying process makes it possible to evaluate it as a technological process, as well as to show the possibility of its optimization. It should be noted that this method is environmentally friendly and less energy intensive than others.

Ash Fouling

The boiler economizer is a tube heat exchanger located in the final part of the convective duct. In the economizer, water flowing into the boiler is preheated by flue gases. The paper presents the boiler economizer mathematical model with distributed parameters, which can be used to simulate its operation. The developed mathematical model makes it possible to determine temperatures of the tube and working medium of the boiler economizer. In addition, the non-linear mathematical model of the entire boiler allows to analyze the influence of ash fouling of individual boiler heating surfaces on the economizer operation. The proposed model can also be used for monitoring heat and flow parameters of the economizer in on-line mode.

Outlet Temperature

By means of a mathematical model simulating thermal chemical processes taking place in primary reformer radiation chamber, the influence of selected parameters on main characteristic quantities in steam reforming process was investigated. The parameters were divided into inlet parameters on flue gas side, inlet parameters on reaction mixture side and those of radiation chamber geometry. As main characteristic quantities outlet temperature of reaction mixture, maximum temperature of reaction tubes outer surface, outlet temperature of flue gases, absorbed heat, methane conversion into carbon dioxide and carbon monoxide as well as temperature distance from equilibrium were chosen.
