The monitoring of emission components in flue gases is one of the most important topics for continuous gas analysis. This is as a result of legislation for monitoring emissions, e.g. for large combustion plants, and also 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.

The market requires a reliable complete system which is specially designed for the application. The Set CEM 1 (Continuous Emission Monitoring) offered by Siemens is a system which reliably covers all requirements associated with sampling, sample preparation, and gas analysis.

It is possible to determine the concentrations of the gaseous components CO, CO₂, NO, NOx, SO₂, O₂, HCl, HF, NH₃and H₂O.

The ULTRAMAT 23 and OXYMAT 6 are used for the extractive, continuous gas analysis.

The standardized Set CEM provides great clarity and simple configuration facilities. Different versions mean that it is possible to appropriaby adapt the system to the requirements. Standardization also means that not all imaginable versions can be included, and that it may not be possible to implement special requirements such as armored cables, customer-specific documentation or specific conductor labeling without an extra charge.

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

• Sampling probe with weather protection hood
• Heated sample gas line
• Analyzers
• Air-conditioning unit
• NO₂/NO converter
• 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 b
• Single-pole and double-pole fusing
• Condensation bottle
• Coalescence filter

Sampling probe

The standard probe is fitted with a DIN flange DN 65, PN 6. The probe is provided with a self-regulating heater, and has a power consumption of 400 VA. It is supplied with a weather protection hood and 2 µm filter. The maximum dust concentration at the sampling point should not exceed 2 g/m³. The sampling pipe is 1 000 mm long, is made of stainless steel, and has dimensions of 20 x 1.5 mm. The sample gas temperature must not exceed 600 °C.

It is also possible to purchase the Set CEM 1 without sample probe.

Heated sample gas line

The temperature of the heated line is regulated at 200 °C. The power consumption is 100 VA per meter. The internal core is made of PTFE 4/6. The minimum length of the heated line is 5 m, and it can be extended up to 35 m. Lengths greater than 35 m can be provided upon special request. If desired, the system can also be supplied without a heated sample gas line.

Mounting frame

The basis of each Set CEM is the mounting frame with hinged frame (40 HU) for installation of up to five 19" rack units. The mounting frame includes a standardized sample preparation device designed for an ULTRAMAT 23.

The sample preparation system includes a 3/2-way solenoid valve, 3-way switchover ball valve, regulating valve, corrosion-resistant sample gas pump (power consumption 60 VA), condensation trap, room air suction filter with filter element, LOGO for digital display of individual signals in the cabinet, 24 V DC power supply unit (power consumption 70 VA) and moisture sensor with flow cell. Also included is a sample gas cooler (power consumption 200 VA) with integral preliminary condensation trap, heat exchanger, hose pump and teflon filter.

The external dimensions without plinth are 2 000 x 800 x 800 mm (H x W x D). A cabinet depth of 600 mm is also available (not suitable for LDS 6). 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 site for introduction of the hoses and cables.

In addition to the sheet-steel mounting frames for indoor installation, an FRP version is also available for outdoor use. The FRP cabinet is always provided complete with side panels and plinth. The external dimensions are 2 080 x 800 x 600 mm (H x W x D). The FRP cabinet cannot be combined with the LDS 6.

Side panels with doors

Optional outer panels can be selected for the sheet-steel mounting frames. This possibility allows use of the Set CEM in analysis cabinets as a rack design, or in halls as a cabinet design, where a protection class of max. IP54 is required in the latter case. Either a sheet-steel door without b or a glass door can be selected.

Plinth

Plinths with a height of 100 and 200 mm are additionally available.

Cabinet cooling and ventilation

Optionally available are a fan with outlet filter, an air-conditioning unit for indoor installation, and an air-conditioning unit for outdoor installation. The system can be ordered without a fan or air-conditioning unit if the side panels and the door with b are omitted.

The fan with outlet filter has a power consumption of 60 VA, and is fitted in the cabinet wall. The delivery also includes a thermostat with a power consumption of 25 VA.

The air-conditioning unit has a cooling power of 820 VA.

Frost protection heater

The power consumption of the optional cabinet heater is 500 VA. The delivery includes a thermostat with a power consumption of 25 VA for controlling the frost protection heater.

If desired, the system can also be supplied without a frost protection heater.

Fusing of the analog signals

In addition to single-pole fusing of the electronic consumers, it is possible to provide double-pole fusing.

Removal of condensation

Either a 5 or 10 liter condensation bottle can be provided as an option. It is also possible to order the system without a condensation bottle if the condensation can be removed on-site.

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 power consumption is 520 VA. The flow rate is 90 l/min. A 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.

Analog signal processing

As standard, the analog signals are simply connected to isolating terminals. As an option, the analog signals can be processed twice without electrical isolation by a diode module, or twice with electrical isolation.

Analyzers

The standardized set is prepared for an ULTRAMAT 23. The system can be supplemented by a second ULTRAMAT 23, OXYMAT 6 and/or LDS 6. Various measured components and measuring ranges can be selected. Other combinations of components and ranges are available on request. In such a case it must be checked whether the desired certificates and approvals are available.

Example setup, may deviate.

A sample is extracted via the thermostatically-controlled sample gas probe. The dust concentration may be up to 2 g/m³, the sample gas temperature up to 600 °C. The gas is transported to the analysis cabinet via a heated sample gas line. The heating prevents condensate. The gas cooler cools and dries the sample in the analysis cabinet. Condensate is drained. The level in the condensate trap is monitored. For safety purposes, a coalescence filter can be provided in addition to the fine filter and moisture filter which are always present. The sample gas is analyzed by analyzers such as the ULTRAMAT 23, OXYMAT 6 and LDS 6. The ULTRAMAT 23 operates on the basis of molecular-specific absorption of infrared radiation or with an electrochemical oxygen measuring cell. The OXYMAT 6 is an analyzer for bagnetic oxygen measurements. The in-situ LDS 6 laser diode spectrometer operates according to the molecular-specific absorption of near-IR radiation. The delivery may also include an NO₂/NO converter which permits measurement of total nitrogen oxides. In order to qualify the set for low or high temperature ranges (-5, +45 °C), it is possible to use a cabinet heater or air-conditioning unit. Power supply versions are available for 115, 230 or 400 V AC. Electronic consumers can be provided with single-pole or double-pole fusing. The components of the sample preparation system and the analyzers are connected to LOGO modules via a binary signal, and transmit maintenance requirements. The analog signals can be processed either singly or twice. Electrical isolation is additionally possible for the double processing.
