摘要： A method of and a system for combusting fuel in an oxyfuel combustion boiler. Fuel is fed to a furnace of the boiler. Oxidant gas that includes a mixture of substantially pure oxygen and recycled flue gas is fed to the furnace, prior to the feeding of the oxidant gas. At least a portion of the oxidant gas is preheated to generate preheated oxidant gas. The fuel is combusted with the oxidant gas in the furnace so as to generate steam and to produce the flue gas, and at least a portion of the steam is superheated to generate superheated steam. The preheating of the at least a portion of the oxidant gas is performed by using a heat exchanger that transfers heat from a portion of the superheated steam to the oxidant gas.

摘要： A method of controlling a process of generating power in a power plant with a boiler by combusting carbonaceous fuel with substantially pure oxygen. At full load conditions, the method includes introducing a first carbonaceous fuel feed stream into a furnace, introducing a first substantially pure oxygen feed stream into the furnace for combusting the first carbonaceous fuel feed stream with the oxygen, and recirculating a portion of the exhaust gas discharged from the furnace at a first recirculation flow rate to the furnace, to form, together with the first substantially pure oxygen feed stream, a first inlet gas stream having a predetermined average oxygen content, thereby discharging exhaust gas from the furnace at a first discharge flow rate. In second load conditions, corresponding to at most 90% load, the method includes introducing a second carbonaceous fuel feed stream into the furnace, introducing a second substantially pure oxygen feed stream into the furnace for combusting the second carbonaceous fuel feed stream with the oxygen, and recirculating a portion of the exhaust gas discharged from the furnace at a second recirculation flow rate to the furnace, to form, together with the second substantially pure oxygen feed stream, a second inlet gas stream, so as to discharge exhaust gas from the furnace at a second discharge flow rate, and controlling the second recirculation flow rate to be from the first recirculation flow rate to a value providing the second discharge flow rate to be substantially as high as the first discharge flow rate.

摘要： The present invention is a system and method of reducing nitrogen oxides in coal combustion exhaust gases and preventing fire and explosion in pulverized coal systems. The present invention first cools the flue gas exiting a boiler of the pulverized coal system with an air preheater. The present invention removes any particles such as fly ash from the cooled flue gas with an electro-static precipitor or a bag house and recirculates the flue gas. The temperature of the recirculated flue gas is adjusted to a desired temperature and is injected into the pulverizer with combustion air from the air preheater, creating a safer environment for pulverizing the fuel. This mixture of pulverized fuel, air and flue gas is then burned in the boiler, resulting in a cleaner output containing significantly less nitrous oxide.

摘要： Combustion method and apparatus for NOx reduction are capable of easily achieving NOx reduction to an exhaust NOx value of 30 ppm or under. The combustion method is to perform in combination a first NOx reduction step for suppressing generated NOx value to 60 ppm or under (at 0% O2 in exhaust gas, dry basis) by a low NOx burner, a second NOx reduction step for recirculating exhaust gas of the low NOx burner to a burning reaction zone formed by the low NOx burner, and a third NOx reduction step for adding water or steam to the burning reaction zone.
