Winning and storage of bio:energy - where waste organic matter is gasified in pyrolysis reactor, and gases obtd. are subjected to fractional pressure condensn.

摘要

Organic raw materials, e.g all types of plant waste, are collected in an airtight silo sack. The raw materials is then fed in dosed amts. from the sack into a pyrolysis reactor for gasification. The gas obtd. is subjected to fractional pressure condensn.; and the condensate obtd. may be fed into a centrifugal evaporator. The pref. plant includes an elastic sack which is suspended from a cable fitted with a counterweight; and a worm feeder screw drives the raw material upwards into the reactor, which pref. contains a rotating grate. The gas obtd. is pref. fed through a row of pressure condensers, each contg. a radial suction pump and a radial compressor. Used for winning of energy from waste agricultural prods. such as straw etc., or waste leaves, branches and bark obtd. from trees.
