Influence of Ashing Temperature on Predicting Slagging

Mar 26, 2021 · Figure 6a shows the variation of bed temperature with time during circulating fluidized-bed gasification (CFBG) of TMc. (23) During the process of CFBG, the melting substances will adhere to the surface of the bed material or ash particles, resulting in a

Pyrolysis: A Sustainable Way to Generate Energy from Waste

Jul 05, 2017 · 8.2.2. Circulating fluidized bed reactors. The features of this reactor is similar to that of a bubbling fluidized bed reactor described above except the fact that the residence time for the vapours and char is shorter. This makes the gas velocity and the content of char in the bio‐oil to be higher. However, it has a large throughputs advantage.

As Low as Reasonably Practicable (Process Safety) - an

The ALARP (as low as reasonably practicable; see Figure 38.5) principle is sometimes used in the oil and gas industry (UK HSE, 1992).The use of the ALARP principle may be interpreted as, satisfying a requirement to keep the risk level as low as possible provided that the ALARP evaluations are extensively documented.

Wall-to-Bed Heat Transfer in Bubbling Fluidized Bed

Apr 27, 2021 · Measurements were carried out to investigate the wall-to-bed heat transfer in a cross-flow bubbling fluidized bed under continuous solids exchange. The experiments were performed with different tube bundle heat exchangers immersed in a lab-scale gassolid fluidized bed cold flow model 0.4 m × 0.2 m in cross section. Geldart group B particles were used, and the gas velocity, the solids

Petroleum Coke - an overview | ScienceDirect Topics

Petroleum coke can be fired in combination with coals or heavy oils in circulating fluidized bed boilers; alternatively, it can be fired as the sole fuel. Some examples of petroleum coke firing in fluidized bed boilers are shown in Table 5.16. Other examples of CFB boilers firing petroleum coke alone or in combination with other fuels include installations at the Nova Scotia Power Pt.
