A system for providing supercritical steam including a first boiler that generates steam via combusting a first fuel, and a second boiler fluidly connected to the first boiler via a conduit which heats the generated steam to supercritical steam temperatures via combusting a second fuel. A first temperature of the conduit may be below a critical corrosion temperature and a second temperature of the conduit is greater than or equal to the critical corrosion temperature. A combined carbon emission rate of the first boiler and the second boiler may be less than a combined carbon emission rate of generating and heating the steam to supercritical steam temperatures using boilers that only combust the first fuel. The first boiler may be fluidly connected to a heat exchanger that heats the generated steam to a supercritical steam temperature via a flue gas produced by a gas turbine.

System and method for providing supercritical steam

Method and system for adjusting a measured reheat outlet steam temperature ('R') to approximate a reheat outlet steam temperature setpoint ('R') in a boiler. An Ris compared to an R. If the Ris less than the Rand a position of a fuel nozzle tilt (&#x201c;TILT&#x201d;) is below a high limit of the fuel nozzle tilt (&#x201c;TILT&#x201d;), the TILTis increased while a flow rate of a secondary flue gas recirculation (&#x201c;SFGR&#x201d;) is kept constant. If the Ris less than the Rand the TILTis at the TILT, the SFGRis increased. If the Ris greater than the Rand the SFGRis greater than a low limit of flow rate of the SFGR (&#x201c;SFGR&#x201d;), the SFGRis decreased, while the TILTis kept constant. If the Ris greater than the Rand the SFGRis at the SFGR, the TILTis decreased.

Method and apparatus for reheat steam temperature control of oxy-fired boilers

Disclosed herein is a once-through evaporator comprising an inlet manifold; one or more inlet headers in fluid communication with the inlet manifold; one or more tube stacks, where each tube stack comprises one or more substantially horizontal evaporator tubes; the one or more tube stacks being in fluid communication with the one or more inlet headers; one or more outlet headers in fluid communication with one or more tube stacks; an outlet manifold in fluid communication with the one or more outlet headers; and a plurality of flow control devices to dynamically control the fluid flow to a respective inlet header.
