Abstract: A method for improving effectiveness of a steam generator system includes providing a steam generator system including a steam generator vessel, an air supply system and an air preheater. The air supply system is in communication with the steam generator vessel through the air preheater and the steam generator vessel is in communication with the air preheater. The air supply system provides a first amount of air to the air preheater. At least a portion of the first amount of air is provided to the steam generator vessel. A flue gas mixture is discharged from the steam generator vessel. At least a portion of the flue gas mixture flows into the air preheater. SO3 in the flue gas mixture is mitigated before the flue gas mixture enters the air preheater.

A corresponding system includes the glass kiln, the non-catalytic reformers A/B, a flue gas recovery device, a chimney, a high-temperature flue gas fan, a natural gas supply device, and an oxygen supply device. The present disclosure circulates part of flue gas of the glass kiln and increases concentrations of vapor and carbon dioxide in the circulating flue gas, the vapor and the carbon dioxide in the circulating flue gas are subjected to a conversion and reforming reaction with natural gas in the non-catalytic reformers for recycling sensible heat of the high-temperature flue gas and meanwhile generating high-calorific-value water gas at 1300° C. or above, thereby increasing a gross calorific value and a temperature of gas entering the glass kiln, and the high-calorific-value water gas, less unreacted natural gas, and oxygen are sufficiently combusted in the glass kiln.

Abstract: A method of reducing sulfur dioxide emissions of a circulating fluidized bed boiler plant. A first stream of sulfur-containing carbonaceous fuel is fed at a first feeding rate to a furnace of the boiler. A second stream of calcium carbonate containing absorbent having a predetermined d50 particle size is fed at a second feeding rate to the furnace. Oxygen containing gas is fed to the furnace for fluidizing a bed of particles forming in the furnace. Fuel is combusted with the oxygen and the sulfur in the fuel is oxidized to sulfur dioxide. The calcium carbonate is calcined to calcium oxide in the furnace. A portion of the calcium oxide is used to sulfate a first portion of the sulfur dioxide to calcium sulfate in the furnace.

Abstract: A method for improving effectiveness of a steam generator system includes providing air to an air preheater in excess of that required for combustion of fuel and providing the air at a mass flow such that the air preheater has a cold end metal temperature that is no less than a water dew point temperature in the air preheater and such that the cold end metal temperature is less than a sulfuric acid dew point temperature. The method includes mitigating SO3 in the flue gas which is discharged directly from the air preheater to a particulate removal system and then directly into a flue gas desulfurization system. Flue gas reheat air is fed from the air preheater to heat the flue gas prior to entering a discharge stack to raise the temperature of the flue gas to mitigate visible plume exiting and to mitigate corrosion in the discharge stack.

Abstract: For exhaust gas recirculation in internal combustion engines operating, for example, with low sulphur marine diesel oil, an exhaust gas cooler with a cooling unit may be applied that uses a liquid injection system to maintain clean and/or clean a cooling surface of the cooling unit. The liquid injection system may provide liquid into an exhaust gas passage upstream of and or along a condensation starting region the cooling surface, thereby reducing the formation of films and deposits from particulate matter and condensing liquid of an evaporated liquid within the exhaust gas such as sulphuric acid and/or water, as those deposits could otherwise at least partially block the exhaust gas cooler.
