The present application provides an energy control computing device for adjusting one or more steam flow parameters delivered to a steam turbine from a heat recovery steam generator via a number of control devices. The energy control computing device includes a processor in communication with a memory. The processor is programmed to receive a number of measured operating values, identify steam turbine operating limits, identify a number of candidate operating modes meeting steam turbine operating limits, selecting the candidate operating mode maximizing the steam flow parameters while not exceeding the steam turbine operating limits, and directing the control devices to meet the selected candidate operating mode.

Integration of an oxyfuel combustion boiler at elevated pressures and a heat exchanger is achieved to produce carbon dioxide by feeding flue gas comprising carbon dioxide and water from the oxyfuel combustion boiler to a direct contact cooler column wherein water is condensed at a temperature of 0 to 10 C. lower than its dew point; feeding a portion of the condensed water from the direct contact cooler column to the oxyfuel combustion boiler; feeding a portion of the carbon dioxide from the direct contact cooler column to the oxyfuel combustion boiler; and recovering a portion of the carbon dioxide from the direct contact cooler column.

A device for converting a liquid into vapor, having an evaporation surface, a liquid inlet, a heater for heating the evaporation surface, a flow controller, a control unit configured to control a liquid flow rate injected into the liquid inlet, a chamber containing the evaporation surface, and a temperature sensor arranged on the evaporation surface. The control unit is configured to control a heating power of the heater according to a flow rate and to a temperature measured by the temperature sensor according to a predetermined control law. The predetermined control law varies, for each flow rate, non-linearly and inversely proportionally to the difference between a reference temperature of the chamber and the measured temperature.

The method for managing a shut down of a boiler having a duct and heat exchanging components is provided. The heat exchanging component having tubed heat exchanging surfaces within the duct and headers outside the duct. The method includes regulating the temperature of the headers during shut down to a temperature close to the one expected for the steam moving from the tubed heat exchanging surfaces into the headers at a starting up following the shut down.

The present application relates to a steam iron (10) for ironing garments. The steam iron (10) comprises a steam generator (11), an ironing plate (13) and a thermal bridge arrangement (14). The steam generator (11) comprises a main body (11A) and a heating element (12) to heat the main body (11 A). The thermal bridge arrangement (14) extends between the main body (11A) and a thermal coupling area (15) of the ironing plate (13) to heat the ironing plate (13) by conduction of heat from the main body (11A). The thermal bridge arrangement (14) comprises a first portion (16) extending in a first direction (A) away from the thermal coupling area (15) and a second portion (17) extending in a second direction (B) towards the thermal coupling area (15). This invention allows promoting steam generation operating in a high temperature for a better steam capability, while keeping a lower temperature of the ironing plate which prevents damaging garments during ironing.
