As part of the complete reconstruction of the coal-fired boiler house at the Central Boiler House of TEPLO BRUNTÁL a.s., technology for flue gas desulphurisation of coal-fired boilers was delivered. DeSOx technology was used based on dosing freshly ground dry sorbent - sodium bicarbonate into the flue gas. It was the smallest boiler unit in the Czech Republic on which this technology was used. The delivery included installation and commissioning of the technology, including piping routes and nozzles for the boilers.
