Abstract:
Provided is a reheat boiler in which the imbalance in temperature distribution of the temperature of the combustion gas at the outlet of a reheat furnace is reduced by changing the gas flow pattern in the reheat burner. A reheat boiler includes a main boiler configured such that main combustion gas generated in combustion in a burner flows from a furnace through a superheater and evaporator tubes, a reheat furnace that is disposed on the downstream of the evaporator tubes and produces reheat combustion gas by combustion in a reheat burner, and a reheater disposed above the reheat furnace. A closing plate, serving as a drift preventing portion, is provided at a reheat furnace outlet that connects the reheat furnace and the reheater to form a flow path for the combustion gas and the reheat combustion gas so as to narrow the cross-sectional area of the flow path for the combustion gas.
Abstract:
A reheat boiler according to the present invention includes a main boiler configured to make combustion gas originating from combustion in a burner flow from a furnace (102) and pass through a super heater and an evaporation tube bank, a reheat furnace (108) including a reheat burner (107) provided downstream of the evaporation tube bank, and a reheater (109) provided on the upper side of the reheat furnace (108), and also includes a combustion air supply portion (12) that is provided at a position opposite to the reheat burner (107) in the reheat furnace (108) to supply a part of the combustion air as combustion air (11b). By making combustion gas (107a) and the combustion air (11b) collide head-on to facilitate mixing of the combustion gas (107a) with the combustion air (11b), the flow patterns of the combustion gas are changed, whereby temperature unevenness of the combustion gas (107a) at the outlet of the reheat furnace (108) is reduced.
Abstract:
Provided is a marine boiler structure that is capable of remedying non-uniformity in corrosion progression by making the temperature distribution of combustion gas that passes through a superheater uniform, and that is also capable of reducing the level of NOx contained in the combustion gas. In a marine boiler structure configured such that combustion gas generated by combustion in a burner flows from a furnace through a superheater and an evaporator tube bundle, a bottom air port that supplies part of the combustion air as bottom air from a furnace bottom portion of the furnace is provided, the bottom air port is positioned closer to the superheater relative to a burner center line, and an ejecting direction of the bottom air is set within a range inclining in the burner direction from the vertically upward direction.

Abstract:
A parameter storage section stores parameters to be used in electronic control units, in correlation with individual drivers. A driver identification section identifies a driver of a vehicle. A parameter retrieving section retrieves, from the parameter storage section, parameters correlated with the driver identified by the driver identification section, and supplies the retrieved parameters to the electronic control units. A parameter generation section generates parameters based on information related to the driver, and stores the generated parameters in the parameter storage section.
Abstract:
The present invention realizes a screening method and device able to obtain the entire image of a cell as a detailed and accurate (with a good SN ratio) image at high speed by observing the cell image while a Nipkow system confocal scanner is used and the focal position of an objective lens is changed in the optical axis direction. In the present invention, a reagent and a fluorescent marked cell are injected into a well. The focal position is changed in the optical axis direction by using the Nipkow system confocal scanner. Excitation light is irradiated to the well in each focal position, and fluorescent light generated from the cell is received and the degree of activity, and so on, of the cell is measured and displayed on the basis of a slice image of the cell.
