Evaluation of direct quadrature method of moment for the internally circulating fluidized bed simulation with ultrafine particles

Combustion Characteristic Prediction of a Supercritical CO2 Circulating Fluidized Bed Boiler Based on Adaptive GWO-SVM

“…Specific steps are performed as listed below: 6) C′ is updated according to eq 6, and A′ is updated according to eqs 8 and 9. (7) The fitness values of all gray wolves in the population and sort are counted. Compared with the last iteration, the three optimal values are found.…”

“…The supercritical CO 2 (S-CO 2 ) power cycle has received extensive attention and research in the fields of nuclear energy, fossil, concentrated solar energy, waste heat recovery, and ship propulsion system due to its advantages, such as simple system structure, high cycle efficiency, compact components, and environmental friendliness. − In the coal-fired power generation field, circulating fluidized bed (CFB) coal-fired power generation technology, as the most industrialized clean coal combustion technology, has advantages of low NO x emission, simple desulfurization process, high combustion efficiency, and wide coal applicability compared with the pulverized boiler. − The combination of CFB coal-fired power generation technology with the S-CO 2 power cycle has attracted wide attention from scholars all over the world. − The heat transfer temperature of S-CO 2 working fluid ranging from 530 to 650 °C is about 150 °C higher than that of the conventional steam (330–600 °C), which improves the boundary temperature of the furnace, enhances the furnace combustion process and the heat transfer of the heating surfaces, and improves the combustion efficiency and carbon conversion rate of the boiler. , …”
