We have changed the plant into a modern source of heat and electricity capable of combining 4 different alternative fuels, much of which will be locally sourced:
- Sorted and non-recyclable municipal waste
- Biomass
- Dried sewage sludge
- Gas
The multi-fuel boiler is at the top of the current European heating industry and the first construction of this technology in the Czech Republic.
The new technology has ended decades of coal combustion and has significantly reduced emissions, especially carbon dioxide, nitrogen oxide, sulphur dioxide and particulate matter.
It will also put an end to inefficient storage of municipal waste in landfills and will use it in a meaningful way, based on the principles of the circular economy.
The use of a variety of fuels with an emphasis on regional options is the best way to ensure a stable energy supply. It ensures that households, schools, hospitals, offices, cultural, commercial and industrial buildings connected to district heating will never be without heat.

A. TECHNICAL PARAMETERS
Valmet’s delivery scope includes a 40 MWth Valmet BFB Boiler utilizing bubbling fluidized bed combustion technology. The boiler steam production is 52 t/h at 4.2 MPa(g) and 420°C. The multifuel boiler is designed to run from 0 to 100% on refuse-derived fuel (RDF) and/or biomass.
Additionally, the delivery includes a flue gas cleaning system, refurbishment of an existing steel structure and its modification, electrification and instrumentation as well as an upgrade of an existing automation system.
B. EMISSION LIMITS
- Compliance with the latest BAT limits for waste fuel combustion
- SNCR technology to reduce NOx emissions
- Ca(OH)2 and activated carbon dosing technology into the reactor to reduce emissions of SOx, Hg, HF, heavy metals, etc.
