A 3D grid model was established and the Discrete Particle Model (DPM) was employed to simulate the gassolid twophase flow and heat transfer behaviors in the riser. The results demonstrate that the gassolid flow within the circulating fluidized bed (CFB) heat exchanger is capable of achieving rapid heat transfer. The gas was effectively ...

Computational particle fluid dynamics (CPFD) simulation was performed to study coal pyrolysis in a circulating fluidized bed downer containing binary particles (coal particles and heat carrier particles). A suitable drag model, which considers the cluster effect by assuming dynamic equilibrium for particles in and out of the cluster, was incorporated into the CPFD model, which shows acceptable ...

CO 2 from IGCC plant as a heat transfer fluid in organic Rankine cycle in enhanced geothermal systems is found feasible.. Power generation was higher for ammonia in ORC amongst the fluids evaluated. • The lowest possible temperature at which CO 2 could be discharged from the binary heat exchanger was lowest for nButane.. Power recovered from the EGS reservoir is higher than that required to ...

Coated Aluminum. When aluminum is coated with a powder coating, it has essentially been insulated. A variety of factors influence how well the insulation is doing its job, but regardless, heat transfer is slowed. Since the plastic particles are between the aluminum and the environment, it is difficult for convection or radiation to take place ...

In addition, radiative heat transfer is neglected under general low temperature conditions such as coal powder low temperature oxidation . However, when coal is oxidized at low temperature, the radiative heat transfer of low temperature accounts for a large proportion, which has a great effect on thermal transfer [ 10 ].

Pulverized Coal Combustion. PCC technology is a widely utilized technology to generate energy from fossil fuel, especially coal [15]. In this technology, pulverized coal is injected to combust in a furnace in the presence of a controlled level of air. The heat generated is used to produce highpressure steam driving a steam turbine to ...

Every year billion tons of coal are burned in the, with 90% of that being used for electricity generation. Several years ago, a University of Illinois professor reported that to produce 109 kWh/year of power, a plant burns 14,000 tons of coal every day. He noted that the coal that goes to a typical coalfired power plant is crushed to approximately 5 cm in size before it is loaded ...

The effective thermal conductivity of the coal powder is k = W/mK. The heat transfer coefficient between the upper surface of the powder (at x = L) and the surrounding air is h= 5 W/m2K. The surrounding air is at Tamb = 20ºC. The temperature of the lower surface of the coal powder (at x = 0) is equal to the ground temperature, Tg = 22ºC ...

The heat transfer submodel involves five modes: conduction between particles, conduction between particle and wall, gasparticle convection, particlebed radiation, and chemical reaction. The developed model is first verified by comparing the predicted results with experimental data in terms of temperature and gas compositions.

Therefore, after adding pulverized coal, the heat transfer coefficient increased. However, the larger the coaltoair ratio, the temperature rise of the aircoal mixture was lower, so the heat transfer efficiency gradually decreased. ... Powder Technol, 361 (2020), pp. 782790.
