Abstract
A measuring device for a heat exchanger includes a pressure pipe arrangement that is spaced using webs and that has a heating side and an isolation side and that is implemented with at least one heat flow sensor. A heat flow sensor is arranged on the heating side in such a way that at least two temperatures T1 and T2 and the temperature difference thereof can be detected there, and additionally at least one temperature sensor for measuring a temperature T3 is arranged on the isolation side and at a distance to the heat flow sensor.
Claims10
A measuring device for a heat exchanger which has a pressure tube arrangement spaced apart by bars and having a combustion side and an isolation side and is embodied with at least one heat flow sensor, wherein
- the heat flow sensor is arranged on the combustion side in such a way that at least two temperatures T1 and T2, a temperature difference thereof, and a first heat flow Q1 can be determined there, and
- at least one temperature sensor for measuring a temperature T3 is additionally arranged on the isolation side and at a distance from the heat flow sensor such that a second heat flow Q2 between the location of the at least one temperature sensor and a nearest point on an inner side of a pressure tube can be determined,
- wherein the at least one temperature sensor is arranged on a bar of the pressure tube arrangement.
A method for determining heat flows at a pressure tube arrangement spaced apart by bars using a measuring device, the pressure tube arrangement having a combustion side and an isolation side and being embodied with a heat flow sensor, wherein
- the heat flow sensor is arranged on the combustion side in such a way that a first temperature T1, a second temperature T2 and a temperature difference thereof can be determined there, and
- a temperature sensor for measuring a third temperature T3 is additionally arranged on the isolation side and at a distance from the heat flow sensor, the method, comprising:
