METHOD TO DETERMINE SPECIFIC VOLUME HEAT OF COMBUSTIBLE GAS BURNING IN BOMB CALORIMETER AND DEVICE TO FILL CALORIMETRIC BOMB WITH COMBUSTIBLE GAS Russian patent published in 2013 - IPC G01N25/26 G01K17/00 

FIELD: measurement equipment.

SUBSTANCE: method is proposed to determine specific volume burning heat (VBH) of combustible gas in a bomb calorimeter, including preliminary measurement of the calorimetric bomb measurement with the error higher than the required error of specific VBH determination, preliminary determination of an energy equivalent of the calorimeter, filling of the calorimetric bomb with analysed gas in working condition and then with compressed oxygen. When the bomb is filled with a calibrating and analysed gas, final pressure of gas in the bomb and bomb casing temperature are measured. The energy equivalent and specific VBH of analysed gas are calculated with account of water evaporation into the bomb volume. Also a device is proposed for filling of the calorimetric bomb with combustible gas, which additionally contains a vessel with a mixed fluid, having a thermometer for measurement of temperature of a fluid, in which the calorimetric bomb is installed.

EFFECT: improved accuracy of measurements.
