Flue gas measurement or flue gas loss measurement is a procedure that checks the efficiency of oil or gas furnaces. The flue gas loss refers to the energy that escapes unused through the flue gas system. In accordance with immission regulations, the aim is to keep energy loss and pollutant emissions to a minimum. This requires compliance with limits for pollutants and flue gas loss, as well as regular inspections of the fireplace.
CARRYING OUT THE COMBUSTION TEST
To perform an combustion analysis, the heater must first be ready for operation. Then the measuring function and tightness of the combustion analyzer are checked. The flue gas measurement is then carried out during undisturbed continuous operation of the gas or oil fireplace at nominal heat output by measuring the pressure difference between the flue gas and combustion air.
The flue gas probe of the meter is inserted into the measuring opening of the exhaust pipe and the oxygen content, the flue gas temperature and the combustion air temperature are measured simultaneously. For higher measurement accuracy, averaging the flue gas losses over a period of 30 seconds is recommended.
For oil furnaces, CO measurement and measurement of soot number and oil derivatives are also performed as part of the emission test. The CO limit for gas furnaces is regulated by law. The legislation requires regular monitoring of residential furnaces and specifies limits for the exhaust gas loss, the CO content, and the soot number of the flue gases.
