Abstract
A steam power plant includes a boiler unit heated by gas supplied from a pipeline for converting water into steam; the gas may be stored as reserve liquefied gas. A turbine is powered by the steam generated by the boiler unit, and the steam gives up energy to power the turbine; a condenser receives energy-depleted steam from the turbine and includes a cooling circuit with water circulation, and a storage facility for the reserve liquefied gas. A heat exchanger is used for regasifying the liquefied gas and at least a portion of the cooling circuit is in heat-exchange contact with the liquefied gas, so that the liquefied gas is regasified by way of step regasification and supplied to the boiler unit upon a deficiency of gas occurring in the pipeline.
Claims6
A steam power plant comprising:
- a boiler unit heatable by gas supplied from a pipeline for converting water into steam, at least part of the gas being storable as reserve liquefied gas;
- a turbine powered by the steam generated by said boiler unit, the steam giving up energy to power said turbine;
- a condenser for receiving the energy-depleted steam from said turbine, said condenser including a cooling circuit having water circulation;
- a storage facility for the reserve liquefied gas;
- and
- heat exchanger means for regasifying the liquefied gas, at least a portion of said cooling circuit being in heat-exchange contact with the liquefied gas, whereby the liquefied gas is regasified by way of step regasification and supplied to said boiler unit upon a deficiency of gas occurring in the pipeline.
A method of regasifying liquefied gas comprising the steps of:
- supplying gas to a power plant in gaseous form;
- liquefying the gas for storage;
- releasing heat not convertible into useful energy from the power plant;
- heating at least a portion of the liquefied gas by the power-plant released heat for regasifying the liquefied gas into the gaseous form;
- and
- resupplying the regasified gas to the power plant upon a deficiency of the gas supplied to the power plant occurring.
