Abstract
The invention relates to an arrangement for transporting disintegrated solid particles, in which the particles are transported by a quantity of air placed under an over pressure. The weight ratio of the particle/aix mixture lies within a range at which particle transportation gives rise to migrating particle agglomerations. Transportation of the particles is terminated in a particle agglomeration equalizing arrangement, from where the particles are transported further in the form of a particle/air mixture which has been equalized in time. Particle transportation is effected by at least two stages. A first stage in which the weight ratio of the particle/air mixture is greater than 15, and a second stage in which the weight ratio of the particle/air concentration is greater than 5 and lower than the weight ratio of the particle/air mixture in the first stage. The arrangement is used for transporting powdered coal to a powdered-coal burner connected to a combustion furnace.
