Title:
一段式脱硝
Document Type and Number:
Japanese Patent JP4029320
Kind Code:
B2
Abstract:
A system and method is described having a single reaction vessel using superheated steam optionally augmented by oxygen for reducing nitrogen oxides present in a wide variety of organic compounds. Reduction takes place quickly when a steam/oxygen mixture is injected into a fluidized bed of ceramic beads. Reducing additives are metered into the reaction vessel and/or provide energy input to reduce nitrates to nitrogen. The speed of the fluidizing gas mixture agitates the beads that then help to break up solid wastes and to allow self-cleaning through abrasion thereby eliminating agglomerates, and the oxygen, when used, allows for some oxidation of waste by-products and provides an additional offset for thermal requirements of operation.
