Abstract
A method and apparatus for measuring the heating power of a combustible gas. The ratio of the temperature of gases entering and exiting a calorimeter is maintained substantially equal to 1, and the entering air is maintained at its water saturation limit. The calorimeter comprises two concentric cells having a central chimney closed at the top and housing a burner. A coiled tube discharges gases from the chimney. Two temperature probes transmit signals to a microprocessor which actuates a heat exchanger provided in an external wall of the outermost concentric cell.
