Embodiment approach 1

[0027] The power generation system according to Embodiment 1 includes: a power generation unit; a case for accommodating the power generation unit; a ventilator for ventilating the inside of the case; a gas flow path; and a second gas flow path provided in the casing, in which combustion exhaust gas from the power generation unit flows, wherein the second gas flow path joins the first gas flow path in the casing.

[0028] In a power plant, combustible gas may be contained in combustion exhaust gas. As such a case, for example, a case where incomplete combustion occurs in a power generating unit, etc. are mentioned. In this case, if the ventilation fan and the exhaust gas of the fuel cell are separately exhausted from the casing, the combustible gas in the combustion exhaust gas is discharged outside the casing without being diluted. However, according to the above configuration, the combustion exhaust gas of the power generation unit is mixed with the atmosphere (atmosphere) ...

Deformed example 1

[0046] The power generation system according to Modification 1 may include a controller which, when the power generation system is stopped, continues the operation of the rebreather at least until discharge of combustion exhaust gas from the power generation unit stops.

[0047] According to the above configuration, the combustion exhaust gas is mixed with the atmospheric gas in the case by the operation of the rebreather until the discharge of the combustion exhaust gas from the power generation unit is stopped. When the combustion exhaust gas contains combustible gas, the combustion The combustible gas in the exhaust gas is diluted and discharged out of the casing.

[0048] Next, Modification 1 of the power generation system 100A of Embodiment 1 will be specifically described.

[0049] Figure 3A It is a flowchart showing the control of the controller in Modification 1 of the power generation system 100A of 1. Such as Figure 3A As shown, the controller 30 stops the power...

Deformed example 2

[0057] The power generation system of Modification 2 may include, in the power generation system of Embodiment 1, a controller which, when the power generation system is stopped, continues the operation of the ventilator at least until exhaust of the combustion exhaust from the power generation unit stops.

[0058] According to the above configuration, even if combustible gas is contained in the gas remaining in the discharge gas flow path after the discharge of the combustion exhaust gas from the power generation unit is stopped, the combustible gas is diluted by the atmospheric gas in the casing and discharged.

[0059] Next, Modification 2 of the power generation system 100A of Embodiment 1 will be specifically described.

[0060] Figure 3B It is a flowchart showing the control of the controller in Modification 2 of the power generation system 100A of 1. Such as Figure 3B As shown, the controller 30 stops the power generation operation of the power generation system 100...

Abstract

The power generation system of the present invention includes: a power generation unit (1); a casing (2) for accommodating the power generation unit (1); a ventilator (3) for ventilating the inside of the casing (2); ), the first gas flow path (5) in which the gas flowing with the action of the ventilator (3) flows; A second gas flow path (6) for exhaust gas, wherein the second gas flow path (2) merges with the first gas flow path (5) in the casing (2).

Description

technical field [0001] The present invention relates to a power generation system, and more particularly to the structure of a flow path through which combustion exhaust gas of a power generation unit flows. Background technique [0002] Conventionally, there is known a power generation device having a discharge pipe disposed inside a building connected to a pipe extending vertically to discharge exhaust gas generated by a fuel cell (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2008-210631 Contents of the invention [0006] The problem to be solved by the invention [0007] However, in the power generation device described in Patent Document 1, the ventilation fan and the exhaust gas of the fuel cell are discharged from the casing (external container) separately. The exhaust gas is assumed to be, for example, combustion exhaust gas generated by burning fuel ga...
