  • the output port of the third switch 995 as the third output port 97 of the control circuit board 9 is connected to the firing line L of the AC power to power on the three-way solenoid valve, which is situated to the second status when the inlet is connected to the second outlet.
  • the cleaning solution in the boiler 5 is extracted out to the container 10 through the second outlet of the three-way solenoid valve 6 and the water pipe 25 with the dissolved calcareous water scale.
  • the gate signal is transmitted to the control input of the second switch 994 from the second control output port of the controller 991 for one minute to breakover the second switch for one minute.
  • the output of the second switch 994 as the second output port 96 of the control circuit board 9 is connected to the firing line L of the AC power for one minute.
  • the boiler 5 is heated for one minute at a temperature of 220°C by the heating pan 51 made from the first thermostat 52 under the control of the second output port 96. Then go to the step 120.
  • Step 120 the end.
  • the calcareous water scale removing step is adopted with an alternation mode of dissolving, washing and drying. Then dissolve and wash the remaining calcareous water scale in the boiler in a high temperature. The effect of removing is well, the cleaning solution is saved, besides, it shortens the removing working hours.
  • the present invention of a steam station which can remove the calcareous water scale is equipped with a three-way solenoid valve to switch the draw-off from the boiler. It can supply wet steam for the external iron, and remove the calcareous water scale by heating the cleaning solution in the boiler as well.
  • the present invention is provided with well industrial applicability.
