Figure 4.7 Piping for System 2

System 2 illustrated in Figure 4.7 requires piping as follows:

• Connect a stop valve or check valve the nipple at the calibration gas inlet of the detector.

• If a high temperature detector is used and the sample gas pressure is negative, connect an

ejector assembly to the sample gas exhaust hole of the high temperature probe adapter (see

Section 4.1.4, Figure 4.3).

• If a high temperature detector is used and the pressure of the sample gas is 0.49 kPa or higher,

it is recommended that a needle valve (throttle) be used in the sample gas exhaust of the high

temperature probe adapter (see Section 4.1.4, Figure 4.4).

CAUTION

• This is for lowering the sample gas temperature below 700 °C. If the gas temperature is high

and the pressure is also signicantly high, the sampled gas temperature may not reduced

below 700 °C when reaching the detector.

On the other hand, if the sample gas temperature is lowered too much, condensation may be

produced in the high temperature probe adapter. During wintertime, it is recommended that

the high temperature probe adapter be protected with an insulating material to prevent

condensation (see Section 4.1.4, Figure 4.5).

For the usage of the high temperature probe adapter, refer to Section 3.2.2.

• If the dust sticking to the interior of the high temperature probe adapter is to be eliminated by

blow back while using the high temperature detector, the air feed for blow back should also be

taken into consideration.

CAUTION

• The probe is easily clogged if too much dust is contained in the sample gas such as in a utility

boiler or cement kiln. To get rid of the dust with compressed air, the piping from the air source

is connected only during cleaning. Blow back piping can be installed for dust cleaning as

illustrated in Section 4.3.1.
