Flue Gas & Emissions Analyzers | Nova Gas | Portable

A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.

1.4 Natural Gas Combustion - US EPA

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas

Boiler Emissions 101 - Boiler Service | Boiler Parts

With Flue gas recirculation (FGR), a percentage of the flue gas is reintroduced into the combustion chamber (as part of the combustion air) to cool the core flame temperature to reduce NOx. FGR does require more horsepower to drive larger fans because of both the increase in mass as well as the increased temperature of the combustion air being

Testing of flue gas emissions of a biomass pellet boiler

Feb 01, 2013 · If biomass boiler works properly and flue gas emissions are cleaned up, CO 2 should be the dominant composition of the flue gases (green tick in the schematic). The Horiba sampler is equipped with a gas sampling pump that is capable of providing two channels of gaseous samples for the Horiba analyser and the ABB analyser, as shown in Fig. 4 .

Flue Gas Analysers Guide - Keison Products

Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance. Generally when this level is below 0.004 the boiler is considered to be running efficiently. When between 0.004 and 0.008 this indicates a potential problem and investigation and retesting

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Your Guide to Green Boiler Technology | Powerhouse

Condensing boilers are very popular in the hot water boiler market. The extra energy is extracted from the flue gas being brought below its dew point and condensing. Typically the flue gas is routed through the colder return water connection to ensure maximum condensing of the gas (since it is interacting with the coldest water in the system).
