Combustion chamber 16 is made up of the space surrounded by inner side water pipe group 121.In the combustion chamber 16, ejected from burner 15 Fuel it is burned and produce burning gases.

Burning gases path 17 by the space between the outside of inner side water pipe group 121 and the inner side of outside water pipe group 122, with And the space between the outside of outside water pipe group 122 and the inner surface of boiler framework 11 is formed.Flowed in the burning gases path 17 The logical burning gases as caused by combustion chamber 16.

The base end side of aiutage 20 is connected with the opening 111 of the side of the bottom of boiler framework 11 formation, front court Extend upward.Aiutage 20 circulate circulated via combustion chamber 16 and burning gases path 17 and from tank body 10 discharge combustion Burn gas.

In tank body 10 more than, fuel combustion is made by burner 15 in combustion chamber 16 and caused burning gases are passing through While combustion chamber 16 and burning gases path 17, to the water (tank water) of the inside of multiple water pipes 12 (inner side water pipe group 121) Heated, and discharged from aiutage 20 to outside.

On the other hand, from lower header tank 13 supply to the tank water of water pipe 12 burner 15 flame and burning gases Effect is lower to be heated and gasifies (boiling), turns into steam.From tank water generation steam by upper header tank 14 and supply to point From device 30.

The moisture that separator 30 is included to the steam generated in tank body 10 separates.Separator 30 is logical with tank body 10 Cross top connection line 40 and bottom connection line 50 and connect.

Upper header tank 14 is connected by top connection line 40 with the top of separator 30, and the steaming that will be generated by tank body 10 Vapour is supplied to separator 30.

The bottom of separator 30 is connected by bottom connection line 50 with lower header tank 13, and is made in separator 30 from steaming The moisture (water of liquid) that vapour is isolated returns to lower header tank 13.

In the present embodiment, the upper hole 41 as upper pressure loss component is configured with top connection line 40, In bottom, connection line 50 is configured with the bottom hole 51 as low pressure loss component.

Upper hole 41 according to the amount of the steam supplied by top connection line 40 from upper header tank 14 to separator 30, Aridity, make the pressure loss as defined in generation between the gas phase portion of upper header tank 14 and separator 30.

Bottom hole 51 is carried out to the amount for returning to the water of lower header tank 13 from separator 30 by bottom connection line 50 Adjustment.

The water level for being stored in the water of separator 30 is detected in water level detecting portion 31.Water level detecting portion 31 can be by can The more electrode bar constructions detected to the water level (such as low water level, middle water level, high water level) in multiple stages, can also be by energy The level sensor of enough continuously sensed water levels is formed.

The fired state of control unit control boiler 1 and the water level of tank body 10 corresponding with fired state (water pipe 12).

In the present embodiment, control unit based on the water level of the separator 30 detected by water level detecting portion 31 come adjust from The output that water supply line L1 supplies to lower header tank 13, so as to control the water level of water pipe 12.

That is, because water pipe 12 connects with separator 30 via upper header tank 14 and lower header tank 13, therefore, In the case of the pressure loss is not present between water pipe 12 and separator 30, the water level of water pipe 12 is consistent with the water level of separator 30. Even if in addition, in the case of the pressure loss being present between water pipe 12 and separator 30, by the way that the pressure loss is accounted for, Also the water level of water pipe 12 can be controlled based on the water level of separator 30.

Specifically, control unit controls water supply as follows：Make water pipe 12 in the case where the quantity combusted of boiler 1 is few Water level raises, and makes the water level of water pipe 12 reduce in the case of more than quantity combusted.

Here, in the present embodiment, due to being configured with upper hole 41 in top connection line 40, therefore, control unit exists When controlling the water level of water pipe 12, the water level settings of the pressure loss as caused by upper hole 41 have been accounted for.That is, due to separator The low amount corresponding with the pressure loss of pressure of the pressure ratio water pipe 12 of 30 inside, therefore, the water table ratio water pipe 12 of separator 30 Water level it is high.Therefore, control unit considers that the water level of water pipe 12 reduces the situation of amount corresponding with the pressure loss of upper hole 41 To carry out water level control.

However, when the water (tank water) of the inside of water pipe 12 is concentrated in boiler 1, together accompany with steam from tank body 10 To the amount increase of the water of separator 30, the thus separation of the moisture in separator 30 can not be sufficiently carried out, the aridity of steam Reduce.Therefore, in the case where tank water is concentrated, in order to keep the aridity of steam and it is preferred that reducing the water level of water pipe 12.So And if reducing the water level of water pipe 12 in the state of tank water is not concentrated, it is likely that cause water pipe 12 to overheat.

In the present embodiment, boiler 1 is configured to include based on the water level of separator 30 to control the water level of water pipe 12 Control unit, in addition, being configured with upper hole 41 in the top connection line for being connected upper header tank 14 with separator 30, thus Realizing reduces the water level of water pipe 12 in the case where tank water is concentrated.

I.e., in the present embodiment, the water level of water pipe 12 be adjusted to it is lower than the water level of separator 30 with by upper hole 41 Measured corresponding to the caused pressure loss.

Here, the pressure loss in the upper hole 41 in the case of the steam that circulation aridity reduces is than circulation drying The pressure loss spent in the upper hole 41 in the case of high steam is big.That is, the circulation generation in the state of tank water is concentrated The pressure loss in upper hole 41 in the case of steam is more than the steam for generation of being circulated in the state of tank water is not concentrated In the case of upper hole 41 in the pressure loss.Thus, even if in the situation by the water level control of separator 30 for equal state Under, because the pressure loss in upper hole 41 with the development of the concentration of tank water becomes big, so as to also can be with tank water it is dense The development of contracting and the water level of water pipe 12 is adjusted so as to low.Therefore, the water level of water pipe 12 is being carried out based on the water level of separator 30 In the boiler 1 of control, without carrying out complicated control, it becomes possible to while the overheat of anti-antipriming pipe 12, even if in tank water quilt The aridity of steam is also kept as height in the case of concentration.

It should be noted that with the pressure loss in upper hole 41 is set to greatly, the situation that tank water is concentrated (is steamed The situation that the aridity of vapour reduces) under the climbing of the pressure loss become big, therefore, it is possible to be damaged by setting appropriate pressure Lose, to carry out water level adjustment corresponding with the concentration of tank water.

In addition, by configuring bottom hole 51 in bottom connection line 50, it can adjust from separator 30 and return to bottom connection The amount of the water of bobbin carriage 13.Thereby, it is possible to the drastically variation for the water level for suppressing separator 30, therefore, it is possible to make the water of separator 30 Face is stable.Therefore, the appropriate pressure loss is set by using appropriate bottom hole 51, so as to keep appropriate amount While the circulation of tank water, make the water surface of separator 30 stable.

More than, a preferred embodiment of boiler of the present utility model is illustrated, but the utility model does not limit to In above-mentioned embodiment, can suitably be changed.
