Corrosion in fire tube boilers of biomass combustion

Corrosion of heat exchangers is strongly related to ash-deposition on the tubes. In hot water fire tube boilers where the flue gas passes inside the tubes no or little direct impaction of sticky fly-ash particles occurs on the tube walls. Instead, the initial deposits are formed due to thermophoretic forces. These forces are caused by the high temperature gradient between the hot flue gas and

Biomass Incineration Energy Justice Network

Biomass incineration is one of the most expensive, inefficient and polluting ways to make energy -- even dirtier than coal in some ways. Forests are destroyed, the climate is cooked, crop lands are wasted, resources are destroyed and low-income communities and communities of color suffer increased health problems from this unnecessary dirty Boiler Corrosion Prevention for Waste & Biomass BoilersHigh-Temperature Chlorine Corrosion in WtE and Biomass Boilers. Chlorine species are highly responsible for high-temperature boiler corrosion in waste-to-energy and biomass sectors. Chlorine species dissolve in the flue gas during fuel combustion. The saturated chlorine salts condense at the relatively cold heat exchanger surfaces (cold trap).

COMBATING CORROSION IN BIOMASS AND WASTE

One of the main problems with biomass and waste combustion is the production of low melting point chloride-containing deposits, which build up on heat-exchange surfaces, for example superheater tubes, and cause corrosion. The considerable corrosion problems increase the Chlorine Conditioning PENTOLDuring combustion of biomass, chlorine is released in different forms and in different quantities, depending on the type of biomass. In combination with alkali metals contained in the fuel, alkaline chlorides are formed and cause heavy corrosion in the plant.
