Corrosion in the Flue Gas Cleaning System of a Biomass

Feb 02, 2017 · The initial intention was to use both coal and biomass; however since commissioning, only biomass has been used in the boiler. The flue gas flow through the flue gas cleaning system (FGCS) is shown in Fig. 1. The flue gas is led through the flue gas desulfurization unit (FGD) where the majority of sulfur and chlorine species are removed.

Boiler Coking - Boiler Slagging, Biomass Boiler Fouling,

Jul 26, 2021 · The flue gas in the induced draft fan is high-temperature flue gas with a large amount of ash and impurities. Therefore, if the air pressure of ID fan is insufficient, the ash will not be sucked out. The ash will soften and liquidize due to high temperature and oxygen deficiency, which will lead to boiler slagging. Taishan Group is the

Biomass Boiler - an overview | ScienceDirect Topics

Biomass boiler uses thermal energy from the combustion of biomass fuel and air to produce superheated steam from feed water. Biomass fuel usually has a high moisture content, which leads to low boiler efficiency. The boiler efficiency can be increased by using heat recovery devices to decrease the temperature of flue gas before it is exhausted
