The effects of an additive on the release of potassium in
Feb 15, 2018 · For wheat straw, there is a rapid release of K (probably as KCl) as the particle heats and burns, and then a slow release of K from the ash. This has important implications on the boiler slagging if ash deposits are kept at high temperatures, since the ash composition (and hence sintering properties) will change with time.

CiteSeerX — FULL-SCALE TESTS ON CO-FIRING OF STRAW IN A
This paper presents the full-scale tests made on a natural 266 MWe gas-fired boiler where straw shares around 2-3% were co-fired. Straw introduction methods, particle size, feeding velocity, amounts of combustion air and additives have been varied, and the effects on combustion, fouling and corrosion have been studied.

The formation of submicron aerosol particles, HCl and SO2
Apr 01, 1998 · The concentration of submicron particles, HCl and SO 2 in the flue gas from the combustion of straw from wheat, barley and oil seed rape was studied by field measurements on two utility boilers. The concentration of submicron particles varies from 75–2000 mg Nm-3 § and the mean diameter in the range from 0.2 to 0.6 μm. The principal constituents of the submicron particles are …

Bubbling Fluidized Bed Boiler - an overview
This type of boiler can handle fuel with a wide range of particle sizes and fuel blends. The best performance is achieved if the majority of the fuel particles are in the size range 5–50 mm. Finer particles tend to blow out of the bed and burn in the freeboard causing hot zones, which increases NO x production as well as slagging tendencies.

Straw to Energy – Hermes EPC Group
The Straw Boiler The straw boiler is built as a natural circulation boiler. The water which reached a high level of pressure caused by the feed water pump vaporizes in the walls of the boiler. This vapor is heated up to the final, required temperature by the super heater in the steam drum and is …

Biomass fuel leaching for the control of fouling, slagging
The use of straws and other herbaceous biomass as boiler fuel is limited because of rapid formation of boiler deposits (i.e. fouling and slagging), which results in high boiler operating costs. The removal of troublesome elements in biomass that lead to slagging and fouling was tested by washing (leaching) biomass fuels in water. Potassium, sodium, and chlorine are easily removed from rice
