The SNCRMethod (Selective Non Catalytic Reaction) uses injection of ammonia to reduce nitrogen oxides present in stack gas produced by combustion facilities ( power plants, waste incineration plants): 6N02+8NH3 —lt;7N2+12H20 4N0+02+4NH3—*4N2+ 6H20. In order to achieve an optimum injection of ammonia the concentration must be determined immediately after the combustion process …

20210505· So if you want to calibrate the sensor for CO2, then you can do it, but that atmosphere must not contain Ammonia or NO2. It is not a multigas realtime detector. Its use is as a level alarm, not a precise gas level meter. You set it up to detect a threshold to set off an alarm, for example in a room with a gas heater, to detect the buildup of CO2. For a laboratory level detector you will need ...

Choosing the right sensor for your application depends on the expected concentrations, locations, and other factors at your facility. Often, two separate ammonia detectors are required for emergency ventilation control and for machinery room electrical shutdown. A low concentration range detector ( 0 – 250 ppm) can provide suitable resolution and accuracy for initiating emergency ...

1 Introduction. Anthropogenic greenhouse gases, of which carbon dioxide is a major component, are responsible for environmental changes. The atmospheric CO 2 concentration has increased dramatically from its preindustrial level of 280–380 ppm at present day current practices continue unchanged, the atmospheric CO 2 concentration is expected to reach 580 ppm by 2050 1.

Normally you would use smoke detectors, installed at spacing determined by square footage, with height of the ceiling (higher ceilings derate smoke detection) and ventilation taken into consideration. This application presents some other unique problems, though. “There are two common types of smoke detectors: photoelectric and ionization ...

Sensor spacing is determined by the specific hazard locations and the subsequent dangers presented to local personnel. Ammonia Sensor ranges of 050 ppm, 0100 ppm and 0500 ppm can be supplied. Some users prefer to use a few 0500 ppm sensors, as levels at or above the IDLH (300 ppm) will be indicated, and appropriate clothing and respirators can be selected by the emergency response team. …

De mest kosteffektive moniteringssystemer til ammoniak og kuldioxid er, som det vil fremgå af de følgende afsnit, ekstraktive systemer (6). Dvs. systemer, der indebærer en transport af gassen fra målestedet og til en sensor eller en absorbent. Et sådant prøvetagningssystem vil typisk indebære en indledningsvis fjernelse af

The electrode measures ammonia concentration in water samples. A 50 mL bottle of 0,1 M NH4Cl Electrode ...

20211007· For CO2 cascade systems, ammonia and CO2 detection are both required in the compressor room which contains the ammonia system and the cascade heat exchanger. CO2 detection is required instead of ammonia detection in refrigerated and process areas. Detection system design and output functions are similar with the difference being the CO2 sensor selected, warning setpoints at …
