Small combustion system
A small combustion system (abbreviated to KFA) is a combustion system that is designed for private use or for use in small businesses. Their capacity ranges from room stoves to block-type thermal power stations . It is mostly operated with fossil fuels - wood , coal , heating oil or natural gas . The definition is very different in Europe.
The ordinance on small and medium-sized combustion systems has been in force in Germany since 1974 . The definition of small combustion systems only results from the context and differs depending on the fuel. Section 5 contains emission limit values for dust and carbon monoxide in systems that use solid fuels and are operated with a nominal heat output of 4 kilowatts or more. For oil and gas firing systems, according to Section 6, certain limits for nitrogen oxides apply in stages up to 120 and 400 kilowatts; from 400 kilowatts, an efficiency of 94 percent must also be proven.
In Austria, the following is defined in the "Agreement pursuant to Art. 15a B-VG on the placing on the market of small combustion systems": "Small combustion systems are technical facilities up to a fuel heat output of 400 kW, which are intended for the purpose of obtaining useful heat for space heating or hot water preparation are."
In Switzerland , the Clean Air Ordinance (LRV) provides for exceptions for "furnaces with a thermal output of up to 12 kW, which are used exclusively for heating individual rooms".
