The Fouling Behavior of Rice Husk Ash in Fluidized-Bed

Aug 15, 2004 · The gas velocity and air split have great effect on rice husk combustion. At proper operation condition, the rice husk combustion efficiency reaches 97%, and the carbon content in fly ash is between 3% and 8%, whereas CO emissions varies from 200 to 800 ppm, SO 2 ranges from 50 to 100 ppm and NO x ranges from 150 to 220 ppm.

Combustion behaviour of rice husk in a bubbling fluidised bed

Burning of rice husk alone did not result in any detectable fouling, neither in the pilot furnace nor on the deposit probes in the superheater area of the fluidized-bed boiler. After deposit samplings with durations of up to 10 h during rice husk firing, the deposit sampling probe had not collected more than ∼95 mg of deposit material.
