Definitions

  • This invention consists of an improvement procedure applicable to combined-cycle power plants gas turbine-steam turbine in which it is desired to integrate an additional steam flow generated from solar energy.
  • power generation and / or congeneration plants by means of a combined cycle, which integrates a gas turbine and a steam cycle for the recovery of the exhaust gases from the gas turbine, steam cycles of one, two and three pressures (the latter usually including steam reheating at intermediate pressure), whose fundamental difference lies in the level of exergy losses available in said gases, in the process of transmitting energy to the steam cycle.
  • the recovery with a pressure cycle is the one that presents a maximum mismatch and therefore the greatest exergy losses, both due to the important thermal differences and the high temperature of the gases at the exit of the recovery boiler. Therefore, this cycle is practically not used, given its low performance, except in small installations, where its simplicity is imposed.
  • the most common scheme in combined cycle power plants is the two-pressure steam cycle, with which a better adjustment of the absorption curve is achieved, also allowing to reduce the outlet temperature of the gases, reducing the exergy losses and increasing Therefore the performance.
  • the three-pressure recovery cycle has begun to be used, with steam reheating at intermediate pressure, in the upper temperature zone of the gas turbine's exhaust gases.
  • This solution allows the upper pressure of the cycle to be raised up to pressures of the order of 100 bar and to improve the shape of the absorption curve in its adaptation to the transfer, thanks to the three vaporizations at different pressure and the increase of the global specific heat in the steam absorption zone, when the steam flow to be superheated and the superheat steam are added.
  • the improvement process object of this invention consists in working, during the periods of solar steam supply, with a higher pressure of the steam cycle higher than the optimum design of the corresponding combined basic cycle without solar steam input and working with a lower pressure, close to optimum, during periods of operation without solar steam.
  • the steam provided by the solar boiler can be saturated or overheated.
  • superheated steam it can have a significantly lower thermal level than the output of the recovery boiler or have practically the same thermal level as this one. In the latter case, it would be mixed with the outlet of the recovery boiler before entering the steam turbine. In the other case, additional overheating in the recovery boiler would be necessary.
  • saturated steam which is considered the most interesting alternative, it would be mixed with the saturated steam coming out of the high pressure boiler of the recovery boiler and would pass to the superheated one of the same, being thus integrated in the cycle steam.
  • the feed water to the solar boiler would be taken preferably from the outlet of the high pressure economizer from the recovery boiler or from the discharge of the recirculation pump of the high pressure vaporizer thereof.
  • the limit to which it is possible to raise the upper pressure of the cycle is determined by the maximum degree of final permissible humidity in the steam turbine from a maximum overheating temperature determined by the exhaust temperature of the gas turbine gases.
  • the reheating of the steam at intermediate pressure to the temperature allowed by said exhaust gases allows a significant increase in this higher pressure, without reaching high final humidity rates in the steam turbine.
  • the proposed invention basically allows the steam turbine to be sized for the nominal steam flow generated in the recovery boiler in the absence of solar steam, with the upper pressure of the steam cycle corresponding to this condition, so that the admission of a higher steam flow through the steam turbine during periods of operation with solar steam is possible thanks to the characteristic increase in the upper pressure of the steam cycle and therefore , of the pressure at the steam turbine inlet, in this other condition.
  • This lack of oversizing of the steam turbine could even affect its escape, allowing an increase in the losses of the output speed in the condition with solar steam input, limited on the other hand by the slight increase that would occur in the Condensation pressure in the latter condition, if no condenser surfaces or cooling water flow rates are modified, due to the greater flow of steam to condense.
  • the recovery boiler must also be designed for the maximum upper pressure (with solar steam input) and each of its changers must be adequately sized to adapt optimally to the extreme operating conditions, so that under conditions of maximum demand for surface the thermal differentials of design are reached and under conditions of minimum required surface the appropriate typical actions (temperings, recirculations, etc.) are carried out to prevent excessive overheating or unwanted vaporization.
  • the available flow rate of contribution steam to the combined cycle is variable in time, and can oscillate from a null value to the maximum design value.
  • the proposed invention allows to operate satisfactorily in the two extreme conditions indicated, with an optimal regulation for intermediate transitory conditions.
  • the most appropriate solution in this case consists in the use of a regulation system of the power plant by means of variable boiler pressure, so that the turbine admits, with fully open inlet valves, the nominal steam flow generated in the recovery of the Exhaust gases from the gas turbine, in operation as a combined cycle without solar steam, and expand it to the condensation pressure.
  • the intake pressure in the turbine is increased, as the flow of steam to be admitted in the same temperature conditions is higher, so that the pressure at which This steam is generated, both in the solar boiler and at the upper pressure level of the recovery boiler, continuously up to the nominal value corresponding to the maximum contribution of solar steam.
  • said burners in addition to the usual boiler inlet, would be installed in the inlet of the high pressure vaporizer of the boiler, in order not to affect the operating conditions in the superheater with its operation, acting only on saturated steam generated in the recovery boiler.
  • said vaporizer in a smooth tube (without fins) in order to improve its working conditions and decrease its thermal inertia, so that the response capacity of this set is similar to or greater than the disturbance caused by the change of contribution of steam of solar origin to any transitory of this energy, in order to be able to control the operating parameters of the steam cycle in any situation.
  • This solution could be used both for the control of unforeseen transients and periods of absence of sun, as well as for other periods of peak demand of electrical energy in periods of absence of expected sun, if the design of the plant contemplates a maximum power with solar input or with post-combustion greater than the nominal power of the base combined cycle, based on keeping the gas turbine at full load and increasing the power of the steam turbine during those periods. Under these conditions, it would operate with a lower power, that of the combined base cycle, during the hours of lower demand for electricity.
  • the proposed invention in relation to existing solutions offers the following advantages:. Possibility of avoiding or limiting the oversizing and, therefore, the increase in cost of the steam turbine, with respect to the basic dimensions required by the design of the combined cycle plant without making the contribution of solar steam, as well as the need for reduce the load of the gas turbine and, by Therefore, the power generated, under conditions of high solar steam.
  • -. Reduction of exergy losses due to heat transmission of gases to the fluid in the high pressure area of the recovery boiler.
  • the proposed invention offers the following additional advantages:. High stability of the thermal conditions in the intake and early stages of the steam turbine, with significant reduction of the thermal stresses associated with load changes. -. Possibility of avoiding the multi-valve control and the steam turbine regulation stage, with the consequent reduction of costs and improvement of yields. -. Provisions of an important to the macenam and thermal entourage without cost and self-regulated, in the boilers themselves and high-pressure pipes of the installation, which dampens the transients derived from the fluctuations of solar radiation. As a whole, all the above advantages allow reducing investment costs, at least in larger plants, and increasing the overall performance of the plant, for a given solar energy contribution, leading to greater profitability of this type of combined cycle power plants with solar support.
  • the other proposed improvement, using post-combustion burners offers the following advantages:. Improvement of the operating conditions of the equipment, stabilizing its operating parameters before changes in the contribution of solar steam. -. Possibility of controlling the power generated in accordance with various operating programs of the plant. -. Possibility of increasing the participation of solar energy (broadly) in the energy balance of the plant and / or reducing or eliminating the need to increase the size of the superheater of the recovery boiler, using biofuels of biological origin- post-combustion solar.
  • Figure 1 shows an application scheme, including the following equipment: 1.- Heliostat field
  • the total steam flow generated in the recovery boiler is lower than in the operation without solar steam supply, so the vaporizers will have to be sized for the latter condition, being oversized for the first case, which only translates into a small reduction of the minimum thermal differentials in said operating condition, not affecting the functionality of the system at all.
  • the superheater must be sized for the maximum solar steam supply condition, being somewhat oversized in the other extreme operating condition, which is not a problem, as it can be perfectly resolved by tempering with liquid water to control the maximum overheating temperature , as usual in this type of facilities.
  • said oversizing of the superheater with respect to the sizing required by the base combined cycle, can be reduced or avoided by resorting to the use of typical post-combustion burners located at the entrance of the recovery boiler in the periods of solar steam supply , fed with the same fossil fuel of the gas turbine, at the cost of reducing the overall performance and solar participation, or, better still, with biological fuels obtained from biomass.
  • the economizers for liquid heating at the different pressures of the cycle will be optimally sized in each case from a technical point of view and economical, which will normally lead to an oversize in the operation as a combined cycle without solar steam.
  • liquid recirculations or other usual systems of control of this phenomenon should be provided.
  • the absorption curves in the economizers have been represented in the figure without taking into account the possible recirculations required as normally done, given that both representations are totally equivalent from the thermodynamic point of view , and this form, which logically coincides with the typical of a combined cycle of two pressures, facilitates the compression of the diagram.
  • the low temperature recovery zone including the generation of the small steam flow for the deaerator, allows for a higher cooling of the gases in the operating condition with solar steam, due to the fact that it has a higher liquid flow to heat in this condition.

Abstract

Procédé permettant d'améliorer des centrales électriques à cycle combiné avec apport externe de vapeur à partir d'énergie solaire, consistant à utiliser deux procédés complémentaires, qui peuvent également être utilisés indépendamment et présenter des avantages importants pour des installations classiques de ce type. Le premier procédé consiste à faire fonctionner la centrale, pendant les périodes d'apport de vapeur solaire, à une haute pression du cycle de vapeur qui soit plus élevée que la pression nominale optimale du cycle combiné de base correspondant sans apport de vapeur solaire, afin d'augmenter le rendement et de réduire au minimun les dimensions des équipements. Le second procédé consiste à utiliser des brûleurs de post-combustion conçus en association avec la chaudière de récupération, afin de compenser les transitoires de défaillance en alimentation de vapeur externe, et faire en sorte que la puissance générée par la centrale soit indépendante de l'alimentation en vapeur solaire.
