Abstract: A solar chemically recuperated gas turbine system includes an exhaust-gas reformer, a solar reformer and a gas turbine unit with a combustion chamber. The reaction outlet of the exhaust-gas reformer is connected to the inlet of the solar reformer, the flue gas side inlet of the exhaust-gas reformer is connected to the exhaust-gas outlet of the gas turbine. The solar reformer outlet is connected to the combustion chamber inlet. Combustion gas drives the gas turbine after fuel burns in the combustion chamber, and the exhaust gas enters the exhaust-gas reformer. Fuel and steam are mixed and enter the reaction side of the exhaust-gas reformer through a fuel inlet. A reforming reaction between the fuel and steam under heating of the exhaust gas generates syngas. A further reforming reaction occurs by absorbing concentrated solar energy after the syngas enters the solar reformer, and the reactant is provided to combustion chamber.

Abstract: A method of preventing high temperature corrosion on a heat exchanging surface of a biomass boiler, including: a first feeding step, supplying a first biomass fuel to the boiler; a deposition step, performing combustion on the first biomass fuel during initial operation of the boiler, and forming an inert deposition layer on a surface of a heat exchanger of the boiler; a second feeding step, supplying a second biomass fuel different from the first biomass fuel to the boiler; and a normal combustion step, performing combustion on the second biomass fuel. A direct contact of an alkali metal chloride with a metal pipe wall is prevented by forming an inert deposition layer on the surface of the heat exchanger of the boiler in the deposition step, thereby establishing a physical barrier between the heat exchanging surface and the alkali metal chloride to prevent corrosion on the metal pipe wall.

A direct contact of an alkali metal chloride with a metal pipe wall is prevented by forming an inert deposition layer on the surface of the heat exchanger of the boiler in the deposition step, thereby establishing a physical barrier between the heat exchanging surface of the boiler and the alkali metal chloride to effectively solve a problem of preventing corrosion on the metal pipe wall of the boiler.

Abstract: The present invention is related a square packed tower for collection of flue gas CO2. The square packed tower comprises an initial absorbent distributor on the lower end of the flue gas outlet, a vertical plate packer on the lower end of the initial absorbent distributor and a radial diversion gas distributor at the bottom of the square packed tower for delivery of carbon dioxide contained in the flue gas. The radial diversion gas distributor comprises a gas inlet pipe, a butterfly base plate, a butterfly seal plate and numerous radial deflectors. The butterfly base plate is connected with outlet of the gas inlet pipe. The radial deflectors are in radial arrangement between the butterfly base plate and butterfly seal plate along the outlet of gas inlet pipe.

Abstract: A dual-cavity method and device for collecting and storing solar energy with metal oxide particles. Solar radiation irradiates into a light receiving cavity of a dual-cavity, heat-collecting reactor to heat a separating plate and preheat metal oxide particles. The preheated metal oxide particles then enter a reacting cavity. As temperature increases, the metal oxide particles reduce to release oxygen, which discharges through a gas outlet. Reduced metal oxide particles discharge through a particle outlet into a particle storage tank, and then into an oxidation heat exchanger to react with the discharged oxygen discharged to release and transfer stored chemical energy to a medium to be heated. The oxidized metal oxide particles are conveyed into a storage tank, and again enter into a particle inlet of the light receiving cavity. Ambient air controls the gas flow rate in the reactor and the reacting rate in exchanger.
