The proposed steam generator contains a housing 1 having a heat exchanger 2, made with the possibility of moving liquid and vapor heat carrier in it, a means for heating a liquid heat carrier to convert it into a vaporous heat carrier, containing a fuel combustion means having a chimney 6, while the heat exchanger 2 has an inlet channel 3 for supplying a liquid heat carrier and an outlet channel 4 for removing the vaporous heat carrier into the heated object. The means for heating the liquid heat carrier contains at least two sealed containers 10, 11, 12 placed one after the other in the direction of the flue gases, in each of which the corresponding metal-containing heat storage material 13, 14, 15 is located in a solid state. The heat exchanger 2 passes through the indicated containers 10, 11, 12, and the fuel combustion means with chimney 6 is configured to heat each heat storage material 13, 14, 15 to the temperature of the phase transition from solid to liquid state and maintain it in the phase transition state. Each container 10, 11, 12 has a means for monitoring the phase state of the corresponding heat storage material 13, 14, 15, and in the inlet channel 3 of the heat exchanger 2 there is a hermetically sealed means for supplying a heat transfer fluid in an amount that ensures a complete phase transition of the supplied heat transfer fluid into a vapor state when it is heated using the specified heat storage materials 13, 14, 15, which are in the specified state of phase transition.Предлагаемый парогенератор содержит корпус 1, имеющий теплообменник 2, выполненный с возможностью перемещения в нем жидкого и парообразного теплоносителя, средство нагрева жидкого теплоносителя для его преобразования в парообразный теплоноситель, содержащее средство сжигания топлива, имеющее дымоход 6, при этом теплообменник 2 имеет входной канал 3 для подачи жидкого теплоносителя и выходной канал 4 для отвода парообразного теплоносителя в нагреваемый объект.
