| description | PURPOSE:To provide a pressure reducing boiler type vaporizer stable and good in control responsiveness. CONSTITUTION:A pressure reduced steam generating boiler 11 and a pressure reduced steam boiler 12 are installed in communication with each other and a heating medium pipe 14 for passing steam therethrough is provided in the pressure reduced steam generating boiler 11. A heat transfer pipe 17 for passing LNG into the pressure reduced steam boiler 12 is provided. The water temperature and pressure in the pressure reduced steam generating boiler 11 are detected in comparison with the water temperature-to-pressure corresponding relationship in an ideal condition to monitor deviation and, if any deviation is detected a non-condensable gas can be considered to be mixed in the boiler. In the case of a change in the flow amount of LNG, since the judgement by comparison of the water temperature-pressure relationship in the ideal condition is stopped and since a detection signal switching means 23 is switched to effect feed-back control based on the detection signal from a water temperature sensor 18, there is no possibility of erroneous judgement and this method provides a good control responsiveness as well as stability. |
