Buildings need to be heated in winter so Combined Heat and Power (CHP) plants are placed to cities close to humans. Emissions have health impacts locally and globally.

Question

What are the emission factors for burning processes in Finland? Emission factors are estimated in Finland and kettle/plant types used in Finland only.

emissions (from the model) (emissions in mass per time):	energyUse (from Energy use of buildings or other relevant source)

However, this is clearly case-specific data and should be on a case-specific page.

In Finland there are about 700 kettles that has under 5MW fuel power. Same amount is between 5 to 50 MW kettles and over 50 MW kettles there are 200 in Finland. One heating power plant can have several kettles. Many 5-50 MW power plants has also less than 5 MW kettle.

NB BIO = biofuel, whose carbon dioxide emissions are not counted in the total emission amounts of Finland's greenhouse gases, nor are they taken into account in emissions trading. 1) CO2 factor of mixed fuels is an estimate taking into account only the share of fossil carbon. 2) Gasified waste (Product gas) is reported in the fuel categories of the source materials of gasification. Calorific values and emission coefficients describe the properties of fuel as fired, inclusive of moisture content (except for 313, where the measurement unit is tonnes of dry matter). Calorific value of natural gas has been specified in normal conditions (0 °C and 1.013 bar). Emission factors are updated when necessary. (* Revised values. Emission factors for district heating is calculated in Motiva CO2 emission calculation introductions. For district heating joint production emission factor is 220 kg CO2/MWh. In this view other GHGs (CH4 or N2O) are not taken account as CO2-ekv! Emission factors by fuel based on Motiva knowledge is in table 2. Table 12. Emission factors of CO2 by fuel. Fuels kg CO2/MWh Heavy oil 279 Light oil 267 Gas 202 Fluid gas 227 Peat 382 Coal 341 Coke 389 Wood 0 CO2 EF for electricity can be classified in two categories: purchase electricity and own production. EF for purchase electricity is the same as own electricity vendor has informed or average Finnish electricity procurement CO2 EF (= 200 kg CO2/MWh). EF for own electricity production can be used EF from table 2 (fuel based EFs). If electricity is produced in combined electricity, heating production EFs are calculated with “benefit division method”. Method is explained in Motiva introduction (attachment 2). Table 13.

Coefficient of CO2-ekv/CO2 as 1.02 is used in transformation CO2 emission factors to CO2-ekv. factors for electricity and district heating. Table 14.

• Efficiency

Data that have another unit than mg/MJ should be changed.

e.g. t/TJ -> mg/MJ
