摘要： The present invention relates to a method for operating combustion process in a furnace whereby a primary fuel and a secondary fuel are burnt, to an apparatus for injecting liquid oxygen into the furnace and also to the corresponding furnace. The method comprises at least the following steps: the primary fuel and a primary oxidizer are injected into the furnace to create a primary combustion zone, liquid oxygen is injected in as secondary oxidizer such that the secondary fuel combusts with the secondary oxidizer thereby creating a distinct secondary combustion zone. The invention makes it possible for a secondary fuel having a significantly lower calorific value than the primary fuel to be burnt completely in the furnace, such that a product to be produced in the furnace has an improved quality.

摘要： A method and system for fueling of a burner in a direct-fired device using syngas. A gasifier produces syngas from a carbonaceous feedstock such as biomass. The syngas is fed to a syngas burner. A booster burner disposed between the gasifier and the syngas burner increases the temperature of the syngas. The booster burner may be provided with an approximately stoichiometric or sub-stoichiometric amount of oxidant. Operation of the booster burner may be regulated based on the temperature of the syngas. The syngas burner may be used to direct-fire a device requiring a relatively high flame temperature, such as, for example, a lime kiln.

摘要： Method for reducing a formation of nitrogen oxide on a primary side of a furnace and reducing or avoiding nitrous oxide and ammonia slip in an offgas of the furnace in which a fuel is burned in a combustion process having at least two stages. The method includes passing a fuel consecutively through each of a plurality of bed areas of a combustion bed of the furnace. A primary gas including oxygen is fed individually to each of the bed areas so as to burn the fuel in the combustion chamber of the furnace. A secondary gas including oxygen is introduced into a downstream offgas burn-out zone, so as to after-burn incompletely burned offgas components formed during the burning of the fuel. Partial offgas streams from the combustion bed areas are axially mixed by injecting a water-gas mixture as at least one free jet above a surface of the combustion bed upstream from the downstream offgas burn-out zone so that the at least one free jet penetrates the partial offgas streams of the combustion bed areas to reduce a heating value of the offgas between the surface of the combustion bed and the downstream offgas burn-out zone.

摘要： Method of reducing the nitrogen oxide formation (NOx) on the primary side and of at the same time avoiding the formation of nitrous oxide (N2O) and ammonia slip (NH3) in the exhaust gas of a two-stage combustion process and of improving the slag balance, comprising a fixed-bed burn-out zone, through which an oxygenous primary gas flows, above a fuel bed and a downstream exhaust-gas burn-out zone into which oxygenous secondary gas is additionally introduced. The object is to propose a simple and reliably controllable method for reducing nitrogen oxide formation on the primary side in combustion plants, for example grate combustion plants, with considerably higher efficiency, wherein no additional pollutants are produced or the utilization of the energy of the heat content of the combustion gases is only marginally impaired. The object is achieved in that the calorific value of the exhaust gas between the fuel bed surface and upstream of the exhaust-gas burn-out zone is reduced in such a way that an average calorific value of less than 1 MJ/m3 occurs, and the temperature of the fuel bed surface is at least 950° C. until the exhaust gas leaves the exhaust-gas burn-out zone, and the gas temperature above the fuel bed in the region of the rear grate half is more than 1000° C.
