CHAPTER 1
FUNDAMENTALS
The ENERAC Model 700 Integrated Emissions System is an advanced hand-held
analyzer designed to measure, record, and transmit its combustion and emissions
parameters.
The Model 700 emissions analyzer consists of the sampling system,
whose function
is to extract, clean, and dry the sample, and the main unit, which analyzes the
sample and displays the measurements.
It has been designed as a modular system:
•
The base unit contains the sensors, pumps, electronics, and battery.
•
The thermo-cooler (or water-trap) is attached to the side of the analyzer.
•
The probe, thermocouple, and hose-assembly are connected to complete the
sampling system.
Standard analyzer capabilities include measuring ambient temperature, stack
temperature, stack draft, and oxygen.
The available options are separated into three categories:
1. SAMPLE PROBES & CONDITIONING SYSTEMS
A. Inconel probe (9” typical) with latex sampling-line and water-trap
B. Inconel probe (9” typical) with Viton sampling-line and thermoelectric
condenser.
C. Stack-Velocity probe: Stainless-Steel S-type Pitot tube for stack velocity
measurements (in feet/second) and stack gas flow-rate measurements (in
cubic-feet/minute).
2. ANALYZER SENSORS
A. Carbon Monoxide (CO) sensor - SEM type electrochemical sensor
B. Nitric Oxide (NO) sensor - SEM type electrochemical sensor with on-board
temperature monitoring
C. Nitrogen Dioxide (NO2) sensor - SEM type electrochemical sensor
D. Sulfur Dioxide (SO2) sensor - SEM type electrochemical sensor
E. Hydrogen Sulfide (H2S) sensor – Standard electrochemical sensor
F. Carbon Monoxide / Carbon Dioxide / Hydrocarbons sensor bench – Non-
dispersive-infrared (NDIR) sensors
