Abstract
An improved flue gas sensor of a combustion device is disclosed. The flue gas sensor may include a housing and a gas detector disposed within the housing, wherein the gas detector detects or measures at least one gas in a flue gas stream of the combustion device. The housing may also include a water barrier member through which the at least one gas comes into contact with the gas detector. By keeping water and water vapor away from the gas detector, premature failure of the flue gas sensor caused by corrosion may be prevented.
Claims20
A flue gas sensor of a combustion device, comprising:
- a housing comprising a water barrier member;
- and
- a gas detector disposed within the housing, the gas detector detecting or measuring at least one gas in a flue gas stream of the combustion device, the at least one gas coming into contact with the gas detector through the water barrier member.
A method for monitoring at least one gas in a flue gas stream of a combustion device, the method comprising:
- providing a flue gas sensor in direct contact with the flue gas stream, the flue gas sensor comprising a housing enclosing a gas detector for the at least one gas, the housing comprising a water barrier member through which the at least one gas comes into contact with the gas detector;
- and
- allowing the gas detector to detect the at least one gas in the flue gas stream.
