Filed: 1997-09-11
Abstract: The method involves continuously conveying a gas, and combustion- and cooling air in a constant ratio and with equal pressure, temperature, and humidity, over gas- and air measurement devices (2-4). The gas and combustion air are supplied to a burner (5) housed in a heat exchanger (6), and the energy freed during combustion is transferred into the cooling air. The rise in temperature of the cooling air is recorded and is used as a measure of the combustion value. The method involves conveying a gas, as well as combustion- and cooling air in a constant ratio and with equal pressure, temperature, and humidity, continuously over gas- and air measurement devices (2-4) coupled with each other. The gas and the combustion air are supplied to a burner (5) housed in a heat exchanger (6), and the reaction energy freed during combustion and contained in the exhaust fumes is transferred by the heat exchanger into the cooling air. The rise in temperature of the cooling air is recorded and is used as a measure of the combustion value of the gas. An additional burner is provided for safety reasons, over which the predominant part of the gas supplied to the measurement devices is burnt. Steam contained in the exhaust fumes of the additional burner is condensed, collected in a container (21), prepared, and supplied as supply water to a reservoir (1) necessary for the humidification and cooling.
