Combustion plant test room and laboratory

The laboratory of experimental combustion is focused on the research of wood and non-wood biomass combustion, or biodegradable waste. We also deal with the development and design of hot air and hot water heat appliances. We test boilers with outputs of 10 to 200 kW.

The critical equipment is a measuring corner for testing local hot air and hot water heaters with an output of up to 50 kW. With its parameters, this stand fully corresponds to the measurement requirements in an accredited laboratory. This allows us to carry out measurements comparable to the state testing room.

As part of development and research, we focus on testing new fuels, but mainly on the development of low-emission sources, increasing efficiency and reducing emissions from boilers, fireplaces and fireplace inserts.

In addition to the measuring corner, the laboratory is also equipped with two-stage combustion technology. The installed combustion system brings the advantages of a separate gasification and combustion part, consisting of a gasification chamber and a hot water boiler with a nominal output of 110 kW. The boiler accessories consist of a gasification chamber with an inclined, fixed grate, a closed tank, a screw fuel feeder, a cyclone ash separator, a flue gas fan and a control, regulation and measurement system. Sawdust, shavings, wood chips or pellets can be used as fuels in a wide range of humidity. Technologies enable above-standard regulation and measurement. The connection makes it possible to regulate the return water temperature or the combustion air temperature.

Fuel testing can be implemented on several types of combustion equipment, such as hot water or hot air fireplaces or fireplace stoves, house boilers with an output of 20-30 kW with manual and automatic stoking.

For the implementation of tests, we can mechanically modify the supplied fuel in a reasonable amount by crushing, or also pelletising or briquetting.

For fuels, we also provide a fundamental fuel analysis - see the Fuel Laboratory, which can also be supplemented by an analysis of the thermal decomposition of fuel using TGA technology.

During the measurement, we monitor standard gaseous emissions (CO, NOx, TOC, O2) and perform standard sampling of PM using the gravimetric method according to ČSN EN 13284-1. Thanks to state-of-the-art equipment for on-line and off-line particle size analysis, it can also perform an analysis of the size distribution of produced PMs. More in the description of the Laboratory of Fine Particles.
