“The reduction in NOx emissions implemented through adding aqueous ammonia to the products of combustion is basically completed. Last autumn, we successfully performed all guarantee measurements, and the technology was deployed in the real operation with the start of the new year. The heating plant alone is still in a very good condition and has not experienced any shutdowns since its commissioning in 1962,” says Luděk Sklenář, Director of the Energy Segment at Unipetrol.
Unipetrol has been improving the operating efficiency and impact on the environment of its largest brown coal-fired heating plant, T700, with an output of 106 MW in the chemical plant in Litvínov on a long-term basis. The heating plant has been operating since 1962 and it underwent a costly renovation in the 1990s. The T700 heating plant is a successor to the original heating plant, T200, which was put into service in 1942 when the site was used to produce aviation fuels. The T200 heating plant was gradually phased out in the 1990s when the current T700 heating plant assumed the role of the main energy and steam source for the site. The subsequent demolition of the T200 in 2016 was the largest demolition in Central Europe over the past 30 years.
