ガス発熱量測定に用いる湿度調節型空気湿潤器

抄録

In the calorific value determination of fuel gases by water-flow calorimeter, the significant error is caused by lower and higher humidity of combustion air introduced to the calorimeter. To improve this disadvantage, humidity adjustable air humidifier was designed. Combustion air humidity is measured by wet- and dry-bulb psychrometer in the unit and controlled to desired humidity by two damper-type regulators fitted in dry and wetted air streams.
This controller is connectable to the Japanese Industrial Standards type calorimeter without any modification. And it was found that the error is eliminated almost completely by the humidity controller.
