ABSTRACT:
A calorimetry systems for the continuous measurement of the heating value of coal, which provides heating value data used to control coal-fired furnaces. The system has apparatus for pulverizing the coal, a gravimetric feeder for providing pulverized coal at a measured mass feed rate, an initiating self-sustained combustion of the coal therein without the need for further supporting fuel gases. Instrumentation measures the flow rates of the cooling air, primary and secondary combustion air as well as the mass flow rates of the coal into the combustor. A computer is provided which is responsive to the measuring instruments (thermocouples and pressure gauges) for controlling the feeding of the coal and fuel gases during initiation of combustion and for computing the heating value of the coal. The computer has a memory with storage for specific heat values of the constituents of the products of combustion of various ranks of coal (bituminous, subbituminous, lignite, etc.) and the average mass fraction of each constituent in the coal by rank so that the heating value thereof can be determined with accuracy.
