Small Combustion Installation - definition
What is a “small scale combustion installation”?
A combustion unit of less than 50 MWth thermal
capacity, traditionally not regulated at the EU level
– Sectors: residential, commercial/ institutional, industrial– Technologies/Fuels: gas, oil, coal, wood..– Types of installation: of which there are a large number
Importance of Small Combustion Installations

Importance of Small Combustion Installations
● Emission of PAHs from residential use of solid fuels and biomass accounts for about half of the total emission of PAHs in EU [COM(2003) 423 final]; in Poland about 84% in 2006Dębski et al., 2009; http://emissions.ios.edu.pl/kcie/Download/Raport_EMEP_2006_PL.pdf
● Emission of PCDD/F from those activities accounts for one third of dioxin emissions in the EU (Quass U., et al., 2000); in Poland about 43% (of national total) Dębski et al.,2009; http://emissions.ios.edu.pl/kcie/Download/Raport_EMEP_2006_PL.pdf

To sum – upTo sum – up::
▪ solid fuels (coal fuels) – main energy source in many countries; low energetic
efficiency of appliances, lack or low efficiency of flue gas cleaning systems
▪ emission factors for small sources can exceed many times the factors of the
same pollutants for industry (PM, HMs, CO, SO, NO, VOCs and POPs,
particularly PAHs, PCDDs/Fs,)
▪ low flue gases exhaust, location in residential areas; the influence on the local
air quality and human health might be greater than their share in total
emissions
and
▪ implementation of EU Policies
EU Strategy - Environmental and Climate Action
CAFE - CAFE - Clean Air for EuropeClean Air for Europe, DG , DG Environment EC - Environment EC - Thematic Strategy on Air Pollution COM(2005) 446 final Brussels, 21.9.2005
Small combustion sources burning coal and wood: one of the sources for particulate matter (PM) pollution to be addressed with priority
The Strategy sets specific long-term target to decrease emissions (for 2020):▪ primary PM2.5 (particles emitted directly into the air) by 59% compared with the year 2000.
The establishment of standards for small heating installations is also envisaged through the new Directive Energy-using Products
The Climate action and renewable energy package - 28 January 2008 sets up three ambitious quantitative targets described as 3x20:
▪ reduce greenhouse gases at least 20% by 2020 (compared with 1990 levels),
▪ reduce energy consumption by 20% through increased energy efficiency,
▪ meet 20% of our energy needs from renewable sources.
EU Energy policy and SCIs – the products for domestic sector
Directive on Eco-design for Energy-using Products (EuP) (2005)
EuP Directive implementation
Directive 2005/32/EC of the European Parliament
Framework Directive for the setting of eco-design requirements for Energy
using Products; 6 July 2005 (Official Journal of the European Union)
Scope of the Directive:– In principle, all Energy using Products– Specific product categories for eco-design requirements
to be defined ( 20 studies launched – 20 Lots, managed by DG TREN EC)
– Measures of action: Setting of eco-design requirements (Implementing Measures)
EuP Preparatory Study – Lot 15 Solid Fuel SCIs ECODESIGN (EC DG XII)
Current state of SCIs – Energy using Products for domestic sector
SCIs – final design product, SCIs – final design product, a a standalone standalone appliance appliance ≤≤ 0,5 MWth output 0,5 MWth output

The combustion process organisation
3 categories of the combustion process
organisation:
counter-current flow; over-fire, overfeed appliances, manually fuelled, the combustion air is leaded in the opposite direction to the fuel stream and the flame is guided in the opposite direction to the fuel stream also – old type of stove, fireplace, insert
cross-current flow; cross-current flow; under-fire, manually fuelled, with distribution of air i.e., primary and secondary air supply for the process (the combustion air is leaded in the opposite direction to the fuel stream, the flame and the flue gas removal is in the middle of the furnace chamber) – semi-automatic and automatic fuelled boilers ,
co-current flow; upper-fire, underfed stoker boiler, automatic fuelled, the combustion air and fuel are leaded in the same direction and the flame is guided in the same direction as the fuel – automatic fuelled coal and biomass boiler
