Bubbling and Circulating Fluidized Bed Technologies are

base technologies in utility and other industries for c

(high/low rank), biomass and various residual materials (sl

Fluidized Beds represent proven and reliable technolog

reference plants and excellent emission values.

Downstream technologies for dry dedusting (Electrosta

Fabric Filter) are available with Envirotherm and are desi

with the latest environmental laws/directives.

BFBs cover the lower capacity range of steam production

Fluidized Bed Combustion:

Available Technologies


21/31

Increase in moisture content (up to 65%):

lower heating value, resulting in higher amount of flue gas

Increase in chlorine content (up to 0,05%):

high potential for High Temperature Chlorine Corrosion i

appropriate design

Increase in content of impurities/ash (up to 10%):to be considered in boiler and equipment design

Increase in sulphur content (up to 0,05%):

use of limestone required in order to meet legal SO2 emiss

New Bagasse = New Challenge


22/31

Use of primary air for fluidization and of secondarycombustion as well as for enhanced temperature and emis

Injection of fuel directly into the bed via several feeding

Proven fluidizing nozzles with low pressure drop,

but even air distribution

Bubbling Fluidized Bed (1)

24/31

Coarse ash classification and re-feed into the BFB combus

high amount of ash in the fuel and

low amount of alkalines in the fuel ash

Desulphurization is possible via limestone injection

Operable load range between 50 and 100%

Application in the lower capacity range

High reliability due to

simple and robust design

good temperature control: avoids agglomerations

Bubbling Fluidized Bed (3)


25/31

Circulating Fluidized Bed (1)

Basic Principles of CFB Combustion

Intense and turbulent mixing of solid fuel,

air and flue gas

Uniform system temperature: no peaks,no agglomerations

No HP-steam bundles in the ash stream:

no bundle erosion

Low and controlled combustion

temperature due to Fluidized Bed Heat

Exchanger technology

Generous residence time:

As a participant in Simtec 2011 ENVIROT

pleased with the introduction of our techno

Brazilian market, and we reaffirm our complethe potential and performance of the Fluidized

Our partnership with DEDINI reinforces thisguarantees that all the advantages of the

Boilers will be fully exploited to the benefit
