System Overview
Lambda Transmitter LT 2/KS1-D/KS1-DK
The Lambda transmitter LT2/KS1-D/KS1-DK is a microprocessor-based
universal meter for directly measuring the concentration of O and the
combustible oxidizing components of gas (CO/H ), displayed as CO
equivalent (CO ), in combustion systems in the leaner than stoichiometric
range ( > 1), in conjunction with combination probe KS1-D.
It has a facility for direct connection to the integrated/combustion management
system and the ETAMATIC. This makes it possible to achieve improved control
mode to ensure optimized oil and gas combustion and automatic adjustment
of combustion to changing combustion conditions.
The Lambda Transmitter LT2/KS1-D/KS1-D also provides the following
functions:
- Measuring the temperature of flue gas and intake air and calculating
combustion efficiency
- Calculating and displaying CO concentration
- Load-dependent and fuel-specific limit curves / limit values
- O control
- Field bus connection
Direct (in situ) measurement of oxygen (O ) and oxidizing off-gas
components (CO/H ) in the crude gas up to 450°C (840°F)
No connection with infiltrated air (CO )
No gas preparation required, measurement direct in the wet flue gas
Setting time to 60% value (T ) < 10 seconds
with standard sampling CO < 2 seconds
Measuring gas temperature up to 300°C/570°F
(up to 450°C/570°F with KS1-DK)
Low calorific output 20...25 W depending on off-gas temperature

The O measuring cell acts as an electrochemical concentration cell and generates a
d.c. voltage which is dependent upon the absolute temperature T and the logarithm
of the O concentration ratio or O partial pressure ratio at the reference and outer O
electrode.
If the sample gas is fed to the outer electrode and a reference gas with a known O
concentration, such as air for example (20.96%), is fed to the inner electrode, if the
temperature is kept constant, this will give the logarithmic relationship, shown below,
between the probe voltage US and the concentration of oxygen in the sample gas.

Theoretical Principles
Measuring Principle
Lambda Transmitter LT 2/KS1-D/KS1-DK
CO/H -2
sensitive electrode Combustible components are adsorbed as oxygen molecules at the
electrode and diffuse to the "three-phase limit" formed by measuring gas,
electrode and zirconium dioxide. In addition to the Nernst voltage U
determined by the oxygen content, the combustible components present
generate an additional d.c. voltage U / H through the sensor.
The sensor voltage is the sum of the two voltages U = U + U /H
(Fig. 1). Even with low concentrations of oxidizing gases such as H or CO,
the mixture potential is much higher than the O signal.
The mixture potential forms very quickly, T times of less than 2 seconds are
achieved. Sensitivity to O and combustible components can be influenced by
the temperature of the sensor. Lower sensor temperatures bring about higher
sensitivity to CO/H and lower sensitivity to O (Fig. 2).
The concentration of oxygen also influences the sensor voltage U .
With higher O content, the sensor voltage in the high CO range drops slightly
(Fig. 3).
However, the combination probe KS1-D may not be used when it is too cold or
else the oxidizing components will influence the O measurement (falsification
of the measurement value to lower values because of oxidation of the non-
burned flue gas components on the O electrode).

With higher O concentrations, more non-burned residue (CO/H ) oxidizes
before it reaches the 3 phase limit. The effect of sensor voltage U as a
function of the O content is shown in the graph below.

It is therefore recommended that the characteristic is calibrated specifically
for the system with a CO reference measurement.
Another indicator for non-burned residue (CO/H ) on combustion systems
is the dynamics of the sensor signal (U ). The higher the content of non-
burned residue, the higher the dynamics. The following figure traces the
rise of the sensor signal over the O value measured with a lambda probe
LS1 on a reference system (12 MW SAACKE gas burner)
with a small load.

1. As a threshold control for monitoring combustion systems
2. For self-adjusting burner control
Fig. a Fig. b
Diagrams a) and b) show that, with a threshold voltage on all 4 systems, it is
possible reliably to detect when a CO limit of above 20 ppm in the flue gas is
exceeded. The threshold control offers a simple, continuous monitoring facility
for combustion systems and gives an alarm message if the burner
characteristic threatens to enter the range of an unacceptably high CO
emission, e.g. from going out of adjustment or clogging.
Diagram b) shows that burner control is possible.
The operating point of the burner control is no longer fixed or determined by
a characteristic field that is programmed in once, but is continuously
determined and re-set interactively during operation.
To do this the fuel/air mixture is changed in the direction of a lower lambda
value (less air, more fuel) until the combination probe KS1-D/KS1-DK shows
the start of incomplete combustion with a strong signal rise from the
CO/H -selective electrode and dynamics. From this point on, the fuel/air
mixture is now changed back a little in the direction of a higher
lambda value (more air, less fuel).
The optimal operating point is found. This process is repeated in cycles so that
the optimal operating points are always maintained even in unfavourable
weather- and system-related conditions.
If the burner characteristic shifts during operation and the combination probe
KS1-D/KS1-DK therefore detects non-burned residue (CO/H ), the operating
point is immediately moved in the direction of a higher lambda value
(more air, less fuel). If the operating point is re-established from time to time,
using the method described here, then slow changes of the burner
characteristic can be tracked.
