Modeling of shale semicoke combustion in cyclone furnaces

Developed a mathematical model of the combustion process of shale semicoke in a cyclone furnace, taking into account the characteristics particles, kinetics of carbon combustion, as well as the decomposition of carbonates in the bottom ash resulting from the post-combustion of coal char. Presents a flowchart of the calculation and the results of numerical experiments performed on the developed mathematical model. The effect of the carbon content of shale semicoke on the overall characteristics of the cyclone burner and flue gas temperature

The application of the regenerative heat exchanger with a moving dense layer of solid heat carrier for heat recovery ash products conversion sulfur shale. The technique of hydraulic and thermal calculation of the regenerative heat exchanger with a moving dense layer, taking into account the thermal characteristics of bottom ash

DEVELOPMENT OF ENERGY-CHEMICAL INSTALLATION WITH COMBINED PRODUCTION OF ENERGY CARRIERS AND TECHNOLOGICAL GAS

The article presents an overview of the current state of work on the integrated use of hydrocarbon raw materials for energy supply to industrial and domestic consumers, as well as generation of process gas. A thermal scheme of an energy-chemical plant with a combined production of energy carriers (thermal and electric energy) and a process gas containing H2 and CO is proposed. The software product was registered in the form of a mathematical model of a partial oxidation reactor, which made it possible to estimate the parameters of gas synthesis at an air flow coefficient of α=0,7, a pressure increase of πk=5, and a specific steam flow rate of 6,5 kg/kg (N2=35,8 %, H2O=50,2%, CO2=5,9%, CO=2,6%, H2=5,5% and temperature 1570 °C), as well as geometrical dimensions of the apparatus D=1,3 m and L=10,8 m
