Methods of and means for accurately measuring the calorific value of combustible gases |
摘要 |
Method of and means for accurately measuring the calorific value of combustible gases wherein a mixture of combustible gas and combustion-supporting gas is burned in a pair of flames, the temperatures of the burned gases in both flames being monitored and the volume ratios of the combustion-supporting gas to the combustible gas fed to both burners being adjusted so as to maintain the average of said temperatures at substantially maximum; the volume ratio of said gases which produces said maximum average temperatures varying substantially directly with the calorific value of said combustible gas; the aforesaid calorific value being proportional to said volume ratio of said gases which maximizes said average temperatures; the flow rates of said gases being measured by a single flow sensing system, preferably, of the turbine flowmeter types, or the volumetric flow rate of said combustion-supporting gas being maintained at a constant value while the volumetric flow rate of said combustible gas is being measured; said calorific value measuring method and means being unaffected by ambient temperature and other varying environmental factors.
