Coal type adaptability for CFB boilers is of great importance because it influences whether the unit can operate safely, economically and environmentally when the coal type is changed. Research is carried out on a 300 MW CFB boiler located in Longyan power plant, Fujian province by burning three types of coal, i.e. Fujian anthracite, Shenhua bituminous coal and Indonesia lignite.

15/12/2006 · The bottom ashes used for test came from the discharged bottom ashes in a 100 MW CFB boiler in which the anthracite and limestone designed for the 300 MW CFB project was burned. The results of this study showed that the bottom ash could be used for cementitious material, road concrete, and road base material.

The unknown NOx distributions inside large-scale CFB (circulating fluidized bed) boilers have always hindered the economy of the SNCR (selective non-catalytic reduction) process. In this study, field tests were carried out on a typical 300 MW CFB boiler, where multi-level 316 L-made probe and Ecom-J2KN/Testo 350 analyzers were used to perform detailed two-dimensional distributions of flue gas

31/12/1997 · The SOPROLIF 250 Mwe CFB boiler, installed in the Provence Power Plant located near Gardanne in the south of France, has been the largest CFB boiler in operation since April 1996. The purpose of the project was to repower with a CFB boiler 250 Mwe the existing unit 4 of pulverized coal in order to keep on burning the local high sulfur coal while ensuring an environmentally friendly operation.

23/9/2019 · However, compared with the pulverised coal boiler, the combustion process of CFB boiler is more complicated because of the larger time delay, significant uncertainty and more coupled variables. In this study, a data-driven proportional–integral-derivative (DD-PID) control strategy is presented for the combustion control of CFB boiler to improve the operating performance under full operating

1/4/2020 · For CFB boilers, k boiler type = 5.25, and for GF boilers, k boiler type = 9.24 (CNPSS, 2011). In addition, in order to investigate the partitioning behavior of trace elements from the feed coal into the bottom ash, the term "relative enrichment factors" was introduced to describe the behavior of trace elements remaining in the bottom ash (Meij, 1994), as shown in Eq.

When the load of Circulating Fluidized Bed (CFB) boiler changes dynamically, the accumulation and consumption of residual char causes a large inertia and hysteresis in the boiler combustion system. Therefore, accurate estimation of the residual char in the boiler is of great significance to the control system and improve the combustion efficiency. Based on the Computational Particles Fluid
