A continuous moving bed solar steam generation and storage system is provided to generate steam for production processes after loss or reduction of received solar energy. The system includes a receiver 10 that receives a flowing stream of particulate material 30 that absorbs solar radiant energy 15 as it passes through beams of the energy 15 received from collectors 14. The heated stream of material 30 passes into a first chamber 40 to heat a tube bundle 42 therein. Heat from the particulate material 30 is transferred to the bundle 42, evaporating the water to generate, reheat (RH) and/or superheat (SH) steam 46. The cooled material 30 passes to a second chamber 60. The material 30 is drained from the second chamber 60 and carried to a cyclone 80 in the receiver 10. The material 30 drains from the cyclone 80 to complete the flow cycle.

A moving bed heat exchanger (155) includes a vessel having an upper portion (200), a lower portion (210) with a floor (272) including a discharge opening therein, and an intermediate portion (205). The vessel directs a gravity flow of hot ash particles (140) received thereby from the upper portion (200) through the intermediate portion (205) to the floor (272) of the lower portion (210) of the vessel, where the hot ash particles (140) are collected. Tubes in the intermediate portion (205) of the vessel direct a flow of working fluid in a direction substantially orthogonal to the direction of the gravity flow of the hot ash particles (140) through the intermediate portion (205) of the vessel such that heat from the hot ash particles (140) is transferred to the working fluid thereby cooling the hot ash particles (140).

A method for managing an amount of energy utilized by a carbon dioxide capture system that includes providing a fuel and a feed stream including oxygen to a combustion system. The feed stream includes a portion of a flue gas stream generated upon combustion of the fuel in the combustion system. The flue gas stream is subjected to a carbon dioxide capture system to remove carbon dioxide therefrom and an amount of at least one of an oxygen stream or the portion of the flue gas stream introduced to the feed stream is adjusted such that the feed stream maintains an oxygen concentration in a range of between 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between about 1.4 GJ/ton of carbon dioxide and about 3.0 GJ/ton of carbon dioxide.

A method is provided for managing an amount of energy utilized by a carbon dioxide capture system. The method includes providing a fuel and a feed stream to a combustion system. The feed stream includes oxygen and a portion of a flue gas stream generated upon combustion of the fuel. The method also includes subjecting the flue gas stream to a carbon dioxide capture system to remove carbon dioxide therefrom, measuring a concentration of oxygen present in the feed stream, and selectively adjusting an amount of the flue gas stream included in the feed stream based on the measured concentration of oxygen in the feed stream. The selective adjustment is performed such that the feed stream maintains an oxygen concentration in a range of between about 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between 1.4 GJ/ton of carbon dioxide and 3.0 GJ/ton of carbon dioxide.
