Project at a Glance Contents on the CD ROM
  • The outermost layer of the paddy grain is the rice husk, also called rice hull.
  • Burning rice husk producedrice husk ash (RHA), if the burning process is incomplete carbonized rice husk (CRH) is produced.
  • Rice husk is a difficult biomass fuel compared with wood and bagasse, due to high silica content of rice husk ash.
  • The most commonly used technologies in Asia are travelling grate, reciprocating step grate system and Fluidized Bed Combustion (FBC) system.
  • Cyclonic Combustion System and Circulated Fluidized Bed Combustion (CFBC) system are also used in rice husk power plants.
  • Rice husk is produced centrally at rice mills and has low moisture content since the paddy is dried to 14% or less before milling.
  • Rice husk ash is mainly used in the steel industry as an insulator in the manufacture of high quality steel forgings. This allows forged steel to cool
    down gradually.
  • Rice husk ash is also used in cement industries as a substitute to portland cement. Research work is also going on regarding silica chip manufacture as the silica content of the ash is very high. Boiler suppliers who can guarantee high quality rice husk ash are in demand in Asia.
  • A large rice-husk power generation plant coming up at the north-western Thakurgaon district of Bangladesh will generate 400 KWh of electricity mainly for small and medium sized rice mills.
  • If 150,000 telecom towers are ‘solarised’, there will be 450 million litres of diesel saved annually. There can also be daytime mitigation of diesel
    consumption through solar applications (typically, for irrigation water pumps): 1,000 MW of avoided diesel power capacity saves 400 million litres of diesel per year. And if 2,000 plants generate power using rice husk as fuel, it will result in 100 million litres of diesel saved.
  • The annual production of rice husk is approximately 4.6 million tons.
  • The husk price is reviewed
    from previous research. The husk price was reported in the range of 100–200 THB t 1
    . Jungingern reported that husk prices have varied in the past between 56 and 216 THB t 1, though 324 THB t 1 in times of extreme rice husk scarcity.
  • Commercially proven rice husk electric power systems in the U.S. depend primarily
    on captive feedstocks of 83,000-112,000 M.T./year
  • The prototype of the gasifier fueled a 10-20 horsepower engine, using 20-25 kg of
    rice husk per hour and producing 33 cubic
    meters of gas per hour.
  • The best estimate on costs for transporting rice husk was provided bythe faculty of Bogor Agricultural University as 200 Rp/M.T./kilometer in two-ton loads with a haul distance of five kilometers.
