Abstract
An apparatus for continuously measuring the heating power of a fuel gas comprises a calorimeter containing a vertical cell whose lower part accomodates a burner. The burner and the cell are respectively fed with fuel gas and with combustion air at a predetermined pressure and feed rate. The calorimeter has an external wall defining an annular vertical space with a wall of the cell. A dividing wall parallel to the external wall divides the annular space into concentric enclosures having a thickness which is small as compared with their length and circumferential size. The enclosures contain a same measurement gas and are operatively associated in a differential gas thermometer arrangement.
