Application

   The monitoring of emission components in flue gases is one . This is a result of legislation for monitoring emissions, e.g. for large combustion plants, and due to the requirements of companies operating process plants who can draw conclusions on the process efficiency from the gas analyses, e.g. with boiler control, DENOX and DESOX plants. It is possible to determine the concentrations of the gaseous components CO, CO2, NO, NOx, SO2, O2, HCl, HF, NH3, H2O, Flow and Temperature.

Benefits                                                                                                       

• Highly exact and reliable monitoring of emission components in flue gases.
• Modular complete package with gas sampling system, sample gas preparation system and gas analyzers from one source.
• Tried and tested harmonized and reliable set.
• Up to 3 extractive analyzers (ULTRAMAT 23) can be used.
• In-situ measurements without sampling and preparation, using LDS 6 laser diode spectrometer; central unit can be built into cabinet.
• Maintenance-friendly cabinet design with hinged frame and uniform design.

Design                                                                                                              

Starting with a mounting frame with sample preparation system, it is possible to add additional units as options. These include:

• Ex Sampling probe with weather protection hood.
• EX Heated sample gas line.
• Analyzers.
• Ex Air-conditioning unit
• NO2/NO converter

Analytical Application Sets

                         Continuous emission monitoring

• Sample preparation extension for an additional ULTRAMAT 23 analyzer
• Single and dual (electrically isolated, not electrically isolated) analog signal processing
• Power supply modules (115 V, 230 V, 400 V)
• Outer panels with steel-plate door or with window
• Single-pole and double-pole fusing

Sampling probe

The standard Ex heated probe is fitted with a DIN flange DN 65, PN 6. The probe is provided with a self-regulated heater. It is supplied with a weather protection hood and filter. The sampling pipe made of stainless steel. The sample gas temperature must not exceed 600 °C.

Heated sample gas line

The Ex heated sample line is self-regulated up to 120°C (The temperature of the heated line can be regulated at 200 °C by a temperature controller).The internal core is made of PTFE 4/6(other material on request).

Mounting frame

The basic of each mounting frame is made of carbon steel with sunshade (other material is available) for installation of up to three 19" rack units. The mounting frame includes a standardized sample preparation system designed for an ULTRAMAT 23. The sample preparation system includes a 3/2-way solenoid (auto calibration) valve, 3-way switchover ball valve, cylinder regulating valve, corrosion resistant sample gas pump, condensation trap, particle filter, air pressure regulator with filter, 24 V DC power supply unit. Also included are a sample gas cooler with integral heat exchanger, hose pump, moisture sensor with flow cell. Teflon tubes connect the components.

Hoses and cables can be connected from the left or right. A distance of 500 mm must be provided on the left or right at the installation site for introduction of the hoses and cables.

The standard system with sample preparation system and electronics is prepared for one ULTRAMAT 23. If a second ULTRAMAT 23 is to be fitted, this option must be selected so that the sample preparation system and electronics are extended accordingly.

In addition to the fine filter and moisture filter which are always present, a coalescence filter can be optionally fitted in the sample preparation system.

Side panels with doors

Optional outer panels can be selected for the sheet-steel mounting frames. This possibility allows use of the CEMS cabinet to analysis up to four stack by switching system.

Cabinet cooling and ventilation

An air-conditioning unit for indoor installation and an air-conditioning unit for outdoor installation. The delivery also includes a thermostat. The air-conditioning unit has a cooling power of 820 VA.

NO2/NO converter

The mounting frame and cabinets can be optionally extended by a 19" rack unit with NO2/NO converter with carbon cartridge. The flow is 90 l/h. An NO2/NO converter is required if the share of NO2 in the total NOx is greater than 5% and/or if total NOx is to be always determined.

Power supply

The system can be designed either for 115 V AC, 230 V AC or 400 V AC (-15 %, +10 %) with 50 or 60 Hz. Three phases, neutral and ground must be provided by the customer at 400 V AC.

Analyzers

The standardized set is prepared for an ULTRAMAT 23. The system can be supplemented by a second ULTRAMAT 23, and/or LDS 6 . Different measured components and measuring ranges are available for selection. Other combinations of measured components and measuring ranges are available on request, but you must check that the desired certificates and approvals are available. The analyzers, measured components and measuring ranges used are described briefly below.

ULTRAMAT 23: CO, NO

For measuring two infrared components.

One or two measuring ranges can be freely set within the limits. The ULTRAMAT 23 carries out automatic self-calibration with ambient air.

ULTRAMAT 23: CO, NO, SO2

For measuring three infrared components.

One or two measuring ranges can be freely set within the limits. The ULTRAMAT 23 carries out automatic self-calibration with ambient air.

ULTRAMAT 23: CO, NO, CO2

For measuring three infrared components.

One or two measuring ranges can be freely set within the limits. The ULTRAMAT 23 carries out automatic self-calibration with ambient air.

The component CO2 has not been type approved by the TÜV

ULTRAMAT 23: CO2

For measuring one infrared component

One or two limits can be freely set within the limits. The ULTRAMAT 23 carries out automatic self-calibration with ambient air. The component CO2 has not been type approved by the TÜV. The ULTRAMAT 23 analyzers can be optionally equipped with an electrochemical oxygen sensor or paramagnetic sensor.

O2: Tested measuring ranges 0 to 10 / 25%

LDS 6: NH3/ H2O

Application for channel 1: Emission monitoring

The power consumption is 50 VA. Suitable for connection of non-Ex sensors, including non-Ex-protected sensor electronics. The delivery includes a pair of sensors for instrument air or N2 on the process side. The pair of sensors is designed for a moderate flow rate of 0 to 120 l/min. The 400 mm long purging tubes are made of stainless steel. The process connection is DN 65, PN 6. The power consumption is 2 VA. Limitation: Applies to measurement paths > 1 250 mm. Necessary gas temperature between 0 and 150 °C.
