Description

[Detailed Description of the Invention] This invention relates to a device for instantaneously generating a large amount of steam.

For example, a conventional water tube boiler generates steam by filling the water tube with water and heating it, so it takes a long time from starting the boiler to generating steam.

Furthermore, once steam generation begins, there is an inconvenience in that heat retention management must be continued even in a usage mode where steam consumption is temporarily interrupted.

This invention was made in order to solve the above-mentioned drawbacks of the conventional boiler, and its purpose is to realize a boiler that can extremely shorten the time required from starting the boiler to steam generation 1, Our objective is to provide a boiler that has an extremely quick start-up time, as well as a boiler that can respond without delay to steam demand that has intermittent steam consumption and pauses. A burner 8 is installed in the flame chamber 1 of the boiler, and its position is such that the flame of the burner 8 can irradiate the entire surface of the head of the ice chamber 30 of the boiler. The device includes a plurality of spray nozzles 5 for spraying water into the water chamber 3 in the water chamber 3 of the boiler near its head, and a water supply system for supplying water to the spray nozzles 5 from outside the boiler. The water pipe 6 is covered with a heat insulating material 7, and all of the water sent from the outside of the boiler toward the boiler is turned into a spray in the water chamber 3.
The water chamber 3 is filled with water and evaporated only by heat exchange inside and outside the walls of the water chamber 3.

Next, the configuration of this invented device will be specifically explained below with reference to embodiments shown in the drawings.

In Figures 1 to 3, 1 is the flame chamber, and boiler A
installed on the head of

8 is a burner, the one in the flame chamber 1 is installed in the father's middle husband, and the one in the head of the ice chamber 30 is placed in a position where it can irradiate the entire surface of the X.

The outer peripheral surface of the boiler A is covered with a heat insulating material 2.

Numeral 4 is a flame tube that penetrates the ice chamber 30 from the head to the tail and allows the flame of the burner 8 to flow through in the direction of the solid arrow. Allow heat exchange to take place between.

That is, although boiler A in this embodiment is a smoke tube boiler, the application of the proposed device is by no means limited to smoke tube boilers, but can also be applied to water tube boilers, and the same effect can be obtained. It is.

That is, in the case of a water tube type boiler, the water tube corresponds to the ice chamber of the present invention, and a spray nozzle is provided in the water tube to spray water within the water tube.

Reference numeral 5 denotes a spray nozzle, which is provided inside the water chamber 3 and near its head.

6 is a water pipe for sending water from the outside of the boiler to the spray nozzle 5, and all of the water sent by the water pipe 6 is sprayed into the water chamber 3 via the spray nozzle 5.

The water pipe 6 is covered with a heat insulating material 7.

9 is a flue, which collects the hot gas that has passed through the flame tube 4 and sends it to the boiler A.
10 is a steam pipe for taking out the steam generated in the water chamber 3 to the outside of the boiler A in the direction of arrow P.

To explain the operation of the device of the present invention, which is constructed in this way, first, the burner 8 burns the fuel, and the flame heats the flame tube 4, and evenly heats the vicinity of the head thereof in particular.

In this state, when water is sprayed from the spray nozzle 5 toward the inside of the water chamber 3, the surface area of the sprayed water is extremely large.
The heat from the flame tube 4 evaporates almost instantaneously into steam, and the required amount of steam can be taken out from the steam tube 10 in an extremely short time.

The reason why the water pipe 6 is coated and insulated with the heat insulating material 7 is that the burner 8
When the flame generated at step 1 flows into the flame tube 4, press the button.
This prevents the loss of heat in the flame due to heat exchange with the water in the water pipe 6, and allows almost instantaneous heat exchange by inputting all of the heat in the flame to heat the flame tube 4. This is done in the interior and exterior of the wall of the water chamber 3, thereby further shortening the time required to obtain a predetermined amount of steam.

Since the instantaneous steam generator according to this invention is constructed as described above, the time required from the start of the boiler to the steam generation 1 can be extremely shortened, and a boiler that starts up extremely quickly can be realized.

The present invention has the effect of realizing a boiler that can meet the demand for steam without delay even when steam consumption and shutdown are intermittent.
