Last year Cofely invested more than EUR 1 750 thousand in the heat farms in Malacky, Senica and Vrakuni. The investments were related to the construction of cogeneration units and the installation of a gas boiler in Malacky, the replacement and installation of a new, more efficient gas boiler in the boiler house for the processing of woody biomass in Senica, and the installation of a installation of a new conveyor for the automatic transfer and dumping of ash in the boiler house for the processing of woody biomass on Železničná Street in Vrakuň.
In Malacky, Cofely started construction of cogeneration units at the end of 2014. The total investment associated with their construction was 1 116 thousand euros. The main advantages of combined heat and power production through cogeneration units include fuel savings, reduction of energy purchase and distribution costs, environmentally friendly production method, availability of emergency sources of electricity in places of continuous consumption and heat production. The new cogeneration units will be launched at the beginning of this year. Another, no less important, investment in the heat management in Malacky was the installation of a gas boiler with an output of 1.4 MW . The modern boiler with higher efficiency covers the peak output of DHW consumption in the summer months at 100 – percent output of the cogeneration unit.
“In addition to the construction of cogeneration units and installation of a gas boiler, Termming in Malacky also reconstructed 120 m of DHW pipelines, had the DHW pipelines from two OST stations and one boiler room circuit to the foot of the apartment buildings regulated. This year, it will continue to regulate the circuits where the consumption quantity or technical condition has changed,” says Martin Žigo, director of the energy production and distribution division at Cofely. In August 2015, Cofely installed a new modern boiler with a total output of 6 MW in Senica. Thanks to its higher efficiency, it will serve mainly as a backup source. The replacement of the older boiler with the new one has contributed to increased operational safety and increased efficiency of heat production.
“Our investment plans in Senica do not end with the installation of a new modern boiler in the wood biomass boiler house. On the contrary, in the near future we plan to invest further funds in projects for the renewal and modernisation of the heat management. Our goal is to ensure a high-quality, long-term and stable heat supply for the inhabitants of Senica. Thanks to the continuous modernisation of our facilities and efficient production and distribution of energy, the price of heat remained unchanged in 2015,” says Martin Žigo, director of the energy production and distribution division at Cofely. Last year, CofeIy, through its subsidiary Termming, invested in the installation of a new conveyor for the automatic transfer and discharge of ash in the wood biomass boiler house at
Železničná Street in Vrakuň. Originally, the ash, which is produced by burning wood chips to produce heat, was manually transported by containers and dumped into a container. Thanks to a modern conveyor, the ash is now automatically transported from the boiler directly to the containers, reducing its release into the air and the overall dustiness in the vicinity of the boiler house. The installation of the new conveyor has increased the safety of the operator and operation and the efficiency of heat production. During the last year, the control system at individual heat transfer stations from the Železničná boiler house circuit was also replaced in a total number of 17 units and the façade of the three largest block boiler houses – Čiližská, Rajčianská and Bebravská – was painted. The replacement of the control system ensured increased efficiency and effectiveness of heat production. The heating season, which started in all three heat farms at the beginning of September 2015, was preceded by summer maintenance, during which Cofely technicians cleaned the boilers, adjusted the combustion processes and checked the functionality and settings of all systems and equipment in the boiler house. Among other things, they also ensured regular calibration of the meters in accordance with current legislation.
