Abstract

PURPOSE:To stably supply liquefied gas by simple installations by connecting the lower liquid part of a liquefied gas container and a flow adjusting means to each other by a pipeline, and pressurizing the liquefied gas container or the pipeline in a liquefied gas supply device for supplying liquefied gas by the flow adjusting means. CONSTITUTION:In a liquefied gas supply device, the lower liquid part of a liquefied gas container 1 and a flow adjusting means 2 are connected to each other by a pipeline 3. The upper space of the liquefied gas container 1 is connected to a compressed air source 5 by a pipeline 4. The flow adjusting means 2 has orifice parts such as orifice, valve, etc. Because the inside of the liquefied gas container 1 is pressurized by the compressed air source 5, the liquefied gas in the pipeline 3 is fed to the flow adjusting means 2 without being vaporized, and thereby the liquefied gas is stably supplied. As a result, the need for connecting many cylinders to each other is eliminated, no vaporizer is required, and installations become simple.

いる。Conventionally, when supplying a relatively small amount of liquefied gas by vaporizing it, the gas was extracted from a liquefied gas cylinder placed at each consumer, and the pressure of this liquid was adjusted using a pressure reducing valve before being supplied to the consumer. ing. In addition, when generating a large amount of gas, a large number of cylinders are connected together, or the liquid gas is forcibly heated and vaporized using a vaporizer before being supplied.

供給ができなかった。Regarding the supply of liquefied gas, it is known that it is advantageous to directly supply and use the liquefied gas to the combustion section in order to construct a simple facility with a minimum number of cylinders and no incidental equipment. However, in this type of liquefied gas supply method, air bubbles are generated in the piping from the cylinder due to the influence of the temperature of the piping and the drop in static pressure as it flows through the piping, and these air bubbles are generated in the pulp used for flow rate control. When passing through the orifice, there are problems in that the flow rate fluctuates and the liquid gas vaporizes, causing ice to form at the orifice, making it impossible to provide a stable fuel supply.
