Industrial boilers should be setup to maximise their combustion efficiency. Measurement of O2 and CO along with efficiency calculations, make the Lancom 4 Portable Gas Analyser an essential tool to all engineers performing industrial boiler service. Optimum boiler performance not only leads to cost saving on fuel but can also reduce NOx emissions.
Gas turbines are increasingly being installed for power generation, many of these with waste heat recovery for steam generation. These plants can effectively use a Lancom 4 Portable Gas Analyser for monitoring emissions, typically at very low levels.
On all power utility boilers there are many fixed analysers monitoring flue gas for combustion efficiency and emissions. The Lancom 4 Portable Gas Analyser offers a simple solution to check the functionality and accuracy of these fixed installations.
The Lancom 4 Portable Gas Analyser is also be used by plant engineers to obtain research data which can aid in the development of more fuel efficient systems. In some countries a portable analyser can also be used as a back-up in case of failure of the continuous emissions monitoring system.
Limestone and shale are heated to very high temperatures and calcined in a rotary kiln to produce cement clinker. Measurement of the kiln exhaust gases is important as NOx levels are directly related to the calcination temperature. The Lancom 4 Portable Gas Analyser provides accurate and repeatable measurements of NO, NO2 and total NOx levels which allows the plant to improve quality ensures good product.
The process can also produce high levels of carbon monoxide which can cause explosions in the precipitator if left unchecked. The Lancom 4 Portable Gas Analyser can be useful to check the function of permanent monitoring systems.
Glass is melted by heating to high temperature silica sand and other materials in a large refractory tank with a regenerator burner arrangement. The burners are gas or oil fired and so, in most regions, emissions have to be monitored. The Lancom 4 Portable Gas Analyser is widely used to monitor these emissions. The Standard Probe features a sintered filter, important in this application, to remove particulate from the gas sample, enabling accurate measurement to be made.
Large volumes of water are used during the manufacture of paper. Typically, a series of cylinders are used to dry the paper, consuming large volumes of steam. In order to ensure sufficient steam is available, all paper mills have large boiler houses and monitoring of emissions is often required on a shift basis. Measurements made with the Lancom 4 Portable Gas Analyser allow the Boiler Plant Manager to trim the boiler controls, maximising efficiency and reducing fuel costs.
Transport of oil and gas over long distances is often achieved by large diameter pipelines. In order to ensure fuel flow, turbine and reciprocating compressor stations are located at regular intervals along the pipeline. The turbine or compressor is fuelled by the content of the pipe line. These pumping stations are usually small and remotely located, but regular emissions checks are required and can be made using the Lancom 4 Portable Gas Analyser.
In the refinery the Lancom 4 Portable Gas Analyser is typically used in the exhaust stack, from combustion or process plant where fuel is burnt (e.g. a tube cracking furnace).
All combustion processes produce different emissions gases depending on the fuel burnt and processed. It is quite usual on these plants to burn fuels which are residues from the refining process. This often leads to high emissions levels of pollutant gases and therefore regular checks are required.
