APPARATUS AND METHOD FOR GENERATING STEAM

摘要

The present invention relates to a steam generating apparatus (10), comprising a body (12) for receiving water to be heated and comprising a first portion (16) comprising a first metal, and a heating device (14) comprising a second portion (18) comprising a second metal, wherein the heating device (14) comprises a heating plate (15) connected with the body (12) by forming an intermetallic layer (20) between the first portion (16) and the second portion (18), and a temperature sensor (24) for measuring a temperature that is indicative of a pressure inside the body (12) is arranged in thermal contact to the heating device (14) outside the body (12). The present invention further relates to a method of controlling the pressure of steam in a steam generating apparatus comprising a body for receiving water to be heated and comprising a first portion (16) comprising a first metal; a heating device (14) comprising a second portion (18) comprising a second metal, the body being connected with a heating plate (15) of the heating device (14) by forming an intermetallic layer between the first portion (16) and the second portion (18), and a temperature sensor (24) for measuring a temperature that is indicative of a pressure inside the body (12), the temperature sensor (24) being arranged in thermal contact to the heating device (14) outside the body (12), the method comprising the steps of setting the target water temperature for a first time period to a first set temperature; setting the target water temperature for a second time period to a second set temperature higher than the first set temperature; and setting the target water temperature for a third time period to a third set temperature lower than the second set temperature.
