Circulating fluidized bed is a relatively new technology with the ability to achieve lower emission of pollutants. Extensive research has been conducted on this technology for the past 10 years because pollution in the world is getting more serious by the day and clean practice will be very crucial for the sustainability of the earth. The importance of this technology has grown recently because of tightened environmental regulations for pollutant emission.

Over the past two decades, CFB technology—including CFB boiler operation and CFB boiler design—has demonstrated its ability to efficiently utilize a wide variety of fuels while still meeting stringent stack emission limits.Our CFB boiler technology allows for a wide range of fuels to be burned efficiently. This includes low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal, and biomass within a wide range of mixing rates.Selective non-catalytic reduction (SNCR) systems can be added to our CFB boilers, leading to even lower NOx emissions.

Circulating Fluidized Bed Boiler | CFB Boiler | GE Power Ultra-Supercritical Circulating Fluidized Bed (CFB) Boilers 660 MWe for lignite B, higher for hard coal, for low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal and biomass, GE offer circulating fluidized bed technologies with different arrangements suited to fuel . Valmet CFB Boiler utilizes circulating fluidized bed … Valmet CFB Boiler (formerly CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time. APPLICATION OF HIGH-LOW BED CFB COMBUSTION TECHNOLOGY TO … igh-low bed technology The high-low bed means that there are two regions in the dense phase zone (fluidizing zone) of CFB. A typical structure of the fluidizing zone is given in Figure 1. Compared to the conventional CFB boiler, the dense phase zone in the high-low bed CFB is cross-sectionally divided into two parts which Fluidized Bed Boiler – an overview | ScienceDirect Topics The most common cause of corrosion in a CFB boiler is the chlorine-induced corrosion. This occurs mostly in the convective heat exchangers. It tends to appear together with high fouling rates due to the presence of alkali and chlorine in fuels that are high in calcium and potassium but low in silica.

Circulating Fluidized-Bed (IR-CFB) Boilers Circulating Fluidized-Bed (IR-CFB) Boilers Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. CFD simulation of hydrodynamics on the dense zone on a 65 … The 65 t/h oil shale-fired high–low bed CFB boiler mainly consists of six parts, that is, furnace containing the dense and the dilute zone, high temperature superheater, low temperature superheater, medium temperature multitubular cyclone, back vertical pass and loop seal, as given in Fig. 1.The structure of the dense phase zone (fluidizing zone) is the core of the high–low bed CFB boiler .

Ltd., Taiyuan … How Circulating Fluidized Bed Boilers Work? Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition.
