    Abstract: The process and the equipment for reducing emissions of pollutants in flue gases from furnace installations (1, 6) comprises a first furnace installation (1) operated with an air excess of, for example, 15%, and a second furnace installation (6) in which afterburning within the stoichiometric range is carried out, with consumption of the residual oxygen. The flue gases leaving the second furnace installation (6) no longer contain any free oxygen, but contain unburned hydrocarbons, carbon monoxide, nitrogen oxides, sulphur dioxide and sulphur trioxide as pollutants. The first-mentioned pollutants--unburned hydrocarbons, carbon monoxide and nitrogen oxides--are converted on a multi-functional catalyst into carbon dioxide, water vapor and nitrogen. The sulphur of the flue gas is oxidized by means of an oxidation catalyst (12) to sulphur trioxide which reacts with the water vapor contained in the flue gas to give sulphuric acid.

    Abstract: During the melting of glass from charging material in furnaces with burners and regenerators for the recovery of waste heat, oxygen and primary fuel are introduced into the area around the flame roots under slightly sub-stoichiometric conditions to cover the heat requirement of the melting process. In order to further reduce the levels of NOx, and CO in the waste gases by re-burning or post oxidation, secondary fuel and, further downstream, additional air are introduced beyond the flame in order to reduce the level of NOx, in or above the checkerwork by means of the secondary fuel and to carry out re-burning or post oxidation downstream by means of the supply of air, so that ultimately approximately stoichiometric combustion takes place. Before the waste gases enter a waste gas stack they are used to preheat the charging material in at least one raw material pre-heater. In order to ensure an almost total recovery of the energy content of the fuel and a continuous flow of the charging material, the temperature of the waste gases coming from the regenerators is measured in front of the entry of the at least one raw material pre-heater, and the quantity of the secondary fuel is regulated according to the temperatures measured.

    Abstract: A process is provided for combusting a low heating value fuel gas in a combustor to drive an associated gas turbine. A low heating value fuel gas feed is divided into a burner portion and a combustion chamber portion. The combustion chamber portion and a combustion air are conveyed into a mixing zone of the combustor to form an air/fuel mixture. The burner portion is conveyed into a flame zone of the combustor through a burner nozzle while a first portion of the air/fuel mixture is conveyed into the flame zone through a burner port adjacent to the burner nozzle. The burner portion and first portion of the air/fuel mixture are contacted in the flame zone to combust the portions and produce flame zone products. The flame zone products are conveyed into an oxidation zone of the combustor downstream of the flame zone while a second portion of the air/fuel mixture is also conveyed into the oxidation zone. The second portion is combusted in the oxidation zone in the presence of the flame zone products to produce combustion products. The combustion products are conveyed into the associated gas turbine and drive the gas turbine.
