Embodiment Construction

[0019] Here, the boiler power usually refers to the so-called latest steam power after the boiler.

[0020] Many installations include multiple boilers with a common flue gas passage. In these boilers, control can be performed by accumulating boiler power or by accumulating electric power when controlling with electric power, which is generally the same as that of the equipment used in the present disclosure.

[0021] The use of renewable fuels is monitored by sampling flue gases. The samples were dated using dating based on the carbon isotope 14C, which separates older fuels—often classified as fossil fuels—from more recently formed renewable fuels formed from organic matter, often plants differentiate. In order to make the samples as representative as possible, the frequency of sampling and / or the amount of sampling is controlled based on the electrical power or the boiler power of the boiler or even both. Control using electric power and boiler power is simple and power ...

Abstract

A method and arrangement for controlling sampling of flue gases by means of which it is possible to control sampling of flue gases for C14 carbon dating. In the method a flue gas sample is taken from the dry flue gas of the combustion plant and it is used for determining the proportions of renewable and fossil fuels using dating based on isotope C14. At least the sampling frequency of the flue gases or the volume flow of the flue gas samples is changed on the basis of the power produced by the combustion plant.

Description

technical field [0001] The invention relates to a method by which flue gas sampling for C14 determination can be controlled. [0002] The invention also relates to a device for carrying out the method. Background technique [0003] Monitoring various emissions in energy production has become increasingly important. For CO2 emissions, it is important to be able to monitor and certify the amount of fuel used since, for example, the amount of emission credits required in emissions trading and any taxes and subsidies for electricity and heat used for production are based on the amount of fuel used. fuel to be sure. Renewable fuels can be used to replace fossil fuels and generate energy with lower carbon dioxide emissions. The use of renewable fuels is often subsidized in a variety of ways, such as price or production subsidies or lower taxes. However, especially in parallel or mixed combustion of fuels classified as fossil and renewable, it is often difficult to show which f...
