TAMEH Czech Power Plant has completed the renovation of three key boilers. The investments exceeding one billion Czech crowns will increase environmental protection and ensure operation of the heat and power plant in the future.

Ostrava, 30 July 2019 – The TAMEH Czech Power Plant, which is the main supplier of energy for the Liberty Ostrava a.s. steelworks, completed the implementation of denitrification of boilers K8, K9, K10, which is crucial for reducing nitrogen oxide emissions in combustion products. After investing in a new K14 fluidised bed boiler and a technology to reduce sulphur oxide emissions, the company has dealt with the task of reducing monitored emissions and completed another part of the plant modernization which is supposed to ensure future operation with minimum environmental impact.

The investment in the denitrification of the key boilers K8, K9 and K10 is the next phase of the process of greening of the heat and power plant boilers K3-K11, which was launched in connection with the adoption of the 2010 Industrial Emissions Directive (IED).

“Together with this Directive, we have made the decision to modernize our plants. In the past, boilers K4 and K11 were designed only for gaseous fuels. The K3, K5, K6 and K7 boilers were replaced by the K14 fluidised bed boiler in 2017 and now we have equipped the remaining K8, K9 and K10 boilers with desulfurization equipment (DeSOx) and with combustion products denitrification equipment (DeNOx),” Kristina Červenková, CEO and Chairwoman of the Board of the Czech-Polish TAMEH energy holding described the gradual process of greening.

The greening process itself was launched in 2013 and is now being finalized with its last phase, which is the completion of the DeNOx project.

“DeNOx, i.e. the reduction of nitrogen oxides, is crucial for us because it will ensure the possibility of further operation of the heat and power plant with minimum environmental impact and it will also contribute to the improvement of air in the area of Northern Moravia,” Kristina Červenková said.

“Technically, the project included major conversion of the primary parts of the boilers, especially a large part of the pressure units. The control system has undergone complete change and some auxiliary technologies were implemented.All this will ensure better control over the combustion process in boilers and achieving necessary conditions for effective reduction of nitrogen oxides in combustion products.” Robert Šteffek, TAMEH Czech Investment Manager, said about the technical specifications of the project.

The project was carried out by two contractors. The renovation of the K9 and K10 boilers was carried out by Provyko s.r.o. and work on the K8 boiler was provided by Energotechnika Energorozruch S.A., a Polish company.

TAMEH Czech s.r.o. represents sophisticated and extensive complex in the industrial energy sector with specific focus on the needs of the metallurgical plant. In terms of efficiency in the area of heating and operation of the local distribution network, the company is fully comparable to specialized energy entities operating on the Czech energy market. The company uses modern technologies to reduce its impact in terms of all environmental aspects. At the same time, it increases the performance and reliability of its equipment, which is necessary to supply energy media to Liberty Ostrava a.s. (Liberty Steel Group). Through gradually implemented environmental investments, the company influences the reduction of emissions, impurities released into the atmosphere. One of the investments is a new fluidized bed boiler put into operation at the TAMEH Czech production plant in Ostrava in 2016. Further investments contain desulphurization and combustion products denitrification projects, which will enable production with lower emissions on other boilers.


Fluidized bed boilers use the principle of combustion of fuels in a fluidized level (fluidized bed), which creates conditions for even combustion of fuel throughout its volume. This allows better combustion of fuel, i.e. high boiler efficiency at lower combustion temperatures while reducing the formation of harmful combustion products.
