METHOD OF UNINTERRUPTED MEASUREMENT OF HIGHEST AND LOWEST SPECIFIC HEAT OF COMBUSTION OF FUEL GASES Russian patent published in 2002 - IPC

FIELD: heat and power engineering. SUBSTANCE: in agreement with given method measurement and comparison cells are placed under identical conditions into isothermal shell of calorimeter, working mixture is continuously supplied into measurement cell where process of complete combustion of gas is conducted with release of heat power Q_x, combustion products are removed and equal quantities of heat are fed per time unit with working mixture into measurement and comparison cells. Constant heat power Q_o is continuously maintained in comparison cell, heat flow between comparison and measurement cells is continuously recorded and heat releases in them are equalized by change of heat flow. Fuel gas-stabilizer is fed in addition into measurement cell and its burning generates additional heat power Q_xd. Flow rate of gas-stabilizer is so varied that relation between additional heat power of gas-stabilizer Q_xd and heat power Q_xd/Q_x of tested gas is not more than 1.1. EFFECT: expanded range of measurement of specific heat of combustion of fuel gases. 2 cl, 1 dwg
