Load and the temperature of solar power plant frequently have greatly changed, and depend primarily on time, date and weather conditions, prove that the steam generator being designed for solar energy thermal-power-generating factory is difficult with this.The quick toggle speed of high-temperature gradient, low spatial demand and low production and operating cost is only to the part in the heat exchanger important need of the generation steam for solar power plant.
Therefore, still need a kind of compacter, more effective heat exchanger for solar power plant, in addition, can also carry out producing and security of operation with lower cost.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of heat exchanger allowing the production of compact arrangement, economical and effective, safe operation.
This object is by realizing according to the heat exchanger of independent claims.Provide in dependent claims and preferably further develop.
Heat exchanger according to the generation steam for solar power plant of the present invention comprises: for the outer shell with inlet nozzle and outlet nozzle of heat eliminating medium.Heat exchanger comprises inlet header for heat-absorbing medium (preferred water) and outlet header further, and inlet header and outlet header are arranged in outer shell substantially.In addition, tube bank is provided with further in outer shell, tube bank comprises multiple tube layer with continuous-tube, and continuous-tube can be arranged around the mode of Flows completely to make heat eliminating medium, and is designed to the flow path flowing to outlet header for heat-absorbing medium from inlet header.Tube bank is arranged in roundabout mode.The heat exchanger producing steam according to the present invention designs according to forced flow principle, makes to be supplied to the heat-absorbing medium of inlet header successively to carry out preheating, evaporation and superheated in flow path, and superheated steam is discharged from outlet header.Preheating, evaporation and superheated institute energy requirement all take from the heat trnasfer in outer shell from heat eliminating medium to heat-absorbing medium substantially.
