によるときも、コストアツプが避けられない欠点
がある。 Conventional reduced pressure boilers of this type were configured to heat and raise the temperature of the fluid to be heated using only the generated steam, but for safety reasons, it was not possible to generate reduced pressure steam of 90°C or higher. Because I can't
For example, it cannot be used for generating heat sources that require high temperatures of 90°C to 120°C, such as heat sources for absorption chillers or heat sources for boiler feed water heating. It was hot. Moreover, when heating multiple fluids that require different temperatures, such as water for hot water supply and water for space heating, a boiler whose internal pressure is set to generate steam at a temperature commensurate with the required temperature is required. Either one must be prepared for each number of fluids to be heated, or the temperature of the fluid to be heated on the low-temperature side must be controlled by setting the internal pressure to generate steam at a temperature that matches the required temperature on the high-temperature side. , in the case of the former, boilers are required for the number of heated fluids with different required temperatures,
The latter method requires a temperature control mechanism, and either method has the disadvantage of inevitably increasing costs.

The water vapor chamber is divided into a plurality of storage chambers, and the condensed water generated in the steam chamber is returned to the water storage chamber, and excess water exceeding a certain amount is removed from the water storage chamber into the high boiling point heat transfer liquid storage chamber. It is characterized in that it is provided with a heat exchange section that heats another fluid to be heated by the high-boiling point heat medium liquid in the high-boiling point heat medium liquid storage chamber.

The liquid is supplied into the liquid storage chamber.
Since the total amount of water sealed in the airtight container is constant, the amount of water dissolving the boiling point raising substance is also the amount of water converted to steam from the total amount of water and the constant amount of water in the water storage chamber. The concentration of the substance that increases the boiling point in the high boiling point heat transfer liquid becomes almost constant, and the temperature of the high boiling point heat transfer liquid is stably maintained at an almost constant level. can be done.
