The high-temperature and high-pressure gas is then cooled by the condensation component 140 to release heat for heating boiler feed water or other media that need to be heated, thereby making the operation more convenient. The cooled medium is then returned to the interior of the evaporation component 120 through the lower tube two 161 for easy recycling, making the operation more convenient. When in use, auxiliary maintenance is carried out through the cooperation of the column 102 and the side rail 103, and the inspection door 180 can also be opened and closed for inspection and maintenance.
