Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.
Yokogawa offers a full range of product solutions including an industry leading zirconia oxygen probe series, as well as a line of cutting edge tunable diode laser spectrometers.
Yokogawa’s new TDLS™8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning.
The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process.
The AV550G multi channel oxygen analyzer system allows for measurements on up to 8 ZR22 probes simultaneously.The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process.
The EXAxt ZR202 transmitter / detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ humidity measurement.
The MG8E paramagnetic oxygen analyzer measures the concentration of oxygen, employing a technique that is based on the fact that a magnet attracts gaseous oxygen. Whereas zirconia oxygen analyzers cannot measure oxygen in flammable gas mixtures, the MG8E can measure not only the oxygen concentration in flammable gas mixtures but also in low concentrations, with high precision.
The MG8G paramagnetic oxygen analyzer measures the concentration of oxygen based on the fact that a magnet attracts gaseous oxygen. Whereas zirconia oxygen analyzers cannot measure oxygen in flammable gas mixtures, the MG8G can measure oxygen concentration in flammable gas mixtures.
The OX400 is a highly accurate and reliable low-concentration zirconia oxygen analyzer that is capable of measuring a wide range of concentrations, from 0-10 ppm up to 0-100 vol%O2.
The OX102 Oxygen Analyzer measures oxygen concentration from ppm to percent levels in a single analyzer and is ideal for ppm-level measurements in applications such as nitrogen reflow furnaces and semiconductor plants.
A furnace for heating slabs needs to be operated under low oxygen conditions at high temperatures of 1000°C and above to prevent oxidation of the steel. The measurement of oxygen concentrations in the furnace is essential in this process. (AN 10M01F01-03E)
In a hot blast stove, the by-product gas produced in a coke oven is burned to preheat the air blast for the blast furnace. To improve the combustion efficiency and conserve energy in a hot blast stove, it is essential to be able to control combustion by measuring and adjusting the oxygen concentration in the exhaust gases.
Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants.
