In the spiral pipe heat exchanger exports terminal, the ammonia steam temperature has been heated up 85 ℃--95 ℃, by now, the ammonia steam had the 45kg-55kg/cm2 ammonia steam pressure, sent in the ammonia steam turbine through the constant temperature pipeline, impelled ammonia steam turbine revolving, led the generator electricity generation;After the ammonia steam makes the merit release energy, the temperature drop, the returns ammonia storage tank, passes through again adjusts the press pump to press into the spiral pipe-type heat exchangers to carry on the next circulation;Including the ammonia steam turbine entire ammonia steam road is becomes the independent closed cycle system, is isolates completely with the outside air;The ammonia steam only plays the carryhome and the shift energy role, in the electricity generation process does not consume the actuating medium, the stored energy carrier water also is only gets up the carryhome and the shift energy function,The waterway also is from becomes the independent closed cycle system, in the electricity generation process also the needless water consumption, through the actuating medium ammonia steam and the stored energy carrier water unceasing shuttle service, transforms through the heat interchanger the solar energy as the actuating medium ammonia steam heat energy and the kinetic energy,With the aid of the ammonia steam turbine heat - machine transformation function and the generator machine - electricity transformation function, has realized the solar energy hot - electricity entire conversion process, transforms continuously the solar energy into the electrical energy, power supply for foreign;The low temperature generating system must solve three big technical keys:One, the anticorrosion (has actuating medium has strong corrosiveness), two is Explosion-proof (Some actuating medium Can have the detonation with the air mix when divulging, controls warm malfunction, elevates temperature suddenly also can have detonation), three is guards against the revolution axis divulging
