testo 380 Combustion Gas and Particle Analyzer

For Biomass Fueled Applications

The testo 380 Combustion Gas and Particle Analyzer.

Unlike any other combustion analyzer, the testo 380 integrates the measurement of the gaseous combustion parameters (ie. O2, CO and CO2) particulate mass (PM), in one simple-to-use package.  The system provides all measurements in real-time and includes data logging capability through powerful software.  Simultaneously reading both fine particulate and the combustion parameters sets a new standard in combustion analysis.

380-Open-Case

The testo 380 is specifically designed to measure the particulates from biomass fueled combustion sources including 6 types of solid fuels:

  • Wood pellets/logs/wood  chips/wood briquettes
  • Wood refuse like coated, painted or coated wood, plywood, particle board, fiberboard or glued wood products
  • Straw and grains
  • Coal - but no pitch-bonded hard coal briquettes, or coke
  • Brown coal, lignite briquettes, lignite
  • Peat fuel

 

testo 380 - Probe for particle measurement

Sampling summary

During the measurement procedure, the probe samples the raw
gas and flows it to the testo 330-2 LL while docked in the system
case. At the same time in a parallel gas path, the raw gas is mixed
with fresh air in the rotating disk diluter (RDD) to condition the fl ue
gas for the particle sensor. The particle probe also measures the
fl ue gas temperature and fl ue draft. To prevent condensation, the
probe heating element maintains constant temperature at 248 °F
/120 °C.

Operation
The particle values are shown as a current particle mass in g/m3,
and an average particle mass in g/m3.
The display can be switched from the numeric to graphic interface.

The RDD
The RDD is made of special ceramics to withstand high
temperatures, corrosive conditions, and particulate friction. The
flue gas passing through the disk is diluted with a defined
quantity of fresh clean air. This reduces the entrained water and
other flue gas contaminants in the instrument gas paths to assure
sample integrity.

380-RDD

The particle sensor
The particle sensor measures the mass of the particles contained
in the measurement gas. A specially calibrated nozzle jets gas
into the oscillating particle sensor. Depending on the mass of the
deposited particles, the oscillation frequency changes allowing
measurement. This process allows a real time measurement to
be shown on the testo 330-2 LL display.

Maintenance
The testo 380 is designed to be a low maintenance analyzer.
The RDD can be easily cleaned using cotton swabs and distilled
water. The particle sensor cleans with a cotton swab, and is
ready to use in a few minutes.
