FUEL GAS CALORIMETER Russian patent published in 2022 - IPC G01N25/22 

FIELD: measuring technology.

SUBSTANCE: invention relates to thermophysical measurements and can be used to measure the heat of combustion of gaseous fuels. The fuel gas calorimeter consists of an external housing, an isothermal shell, a reaction chamber, a single thermocatalytic element, a stable current generator, a control and registration unit, an automatic input device for the calibrated volume of a gas sample, a thermostat, an air dryer, a device for manually entering the calibrated volume of a gas sample, a membrane seal, an indicator of the manual mode of entering the calibrated volume of a gas sample, capillary pneumatic resistances are installed at the inlet and outlet of the reaction chamber to ensure micro-air consumption.

EFFECT: invention makes it possible to simplify the design, reduce the cost, achieve high convergence and reproducibility between measurements.
