The present invention relates to a steam generating device comprising: a first heating tank (3) previously heating supplied water at atmospheric pressure; a high-pressure pump (5) pressing and pumping the previously heated water by the heating tank (3); a plurality of second heating tanks (7) evaporating the water received after being pressed and pumped by the high-pressure pump (5) by reheating using a heater (15); and a third heating tank (9) producing dry steam by reheating wet steam supplied through a steam transfer line (33) from the second heating tanks (7) using a heater (21), and supplying the produced dry steam to a customer (20). The second heating tanks (7) is characterized by including a water injecting nozzle (18) injecting the heated and pressed water pumped from the high-pressure pump (5) to the inside. Therefore, the present invention is capable of reducing time and energy necessary to evaporate raw water to obtain wet steam by injecting the heated and pressed water supplied to the second heating tanks (7) through the water injecting nozzle (18) of high pressures by a form of fine particles, easily controlling a steam output by including the second heating tanks (7) to selectively operate each second heating tank (7), and remarkably improving performance by re-evaporating condensed water using a sorting heater (19) while minimizing a generation of condensed water by combining the wet steam of the second heating tanks (7) and the dry steam of the third heating tank (9) with the condensed water again using a sorting partition (16). |
