Martinská teplárenská, as - greening of energy efficiency and cessation of coal mining
Euro Dotácie, a.s. | Published December 14, 2017 - Deadline February 8, 2018
Martinská teplárenská, as is the central heat source (CZT) for the towns of Martin and Vrútky. The company produces heat and electricity through combined heat and power generation. Through heat networks it supplies heat to consumers and supplies electricity to the regional distribution system. Heat is produced by combustion of fuels (brown coal 65%, wood chips 30% and natural gas 5%) on high-pressure steam boilers. Back-up steam turbines produce electricity, and hot water is produced at the heat exchangers to supply heat to consumers. In order to reduce the impact on the environment, the company has prepared a further stage in the greening of production. The greening is based on the end of the combustion of brown coal with 50% natural gas combustion replacement with an increased share of 50% wood burning. Existing installations will operate a fluidized wood burning boiler and a TG3 backpressure steam turbine. Three cogeneration units consisting of gas engines and electric generators with an electrical output of 3x10 MW will be built to produce electricity and heat to the CZT system. Next, four hot-water boilers for natural gas with a thermal output of 4x15 MW will be built, which will directly produce heat to the CZT system. Hot-water boilers will be operating in extreme winter as top sources or backup sources in the event of a failure of other devices. With this investment, the company will greatly reduce the production of pollutants in the air and meet the legal requirements for further long-term operation, including in relation to the BAT parameters listed in the BREF. The subject of the contract is the construction of a cogeneration engine room, the delivery of three pieces of natural gas engines equipped with electric generators and splint exchanger, the reconstruction of the original hot-boiler boiler, the supply of four hot-water boilers with economizers, the supply and installation of technologies for electric power delivery and operation control. Further specification of the subject of the contract is part of the tender documents (B) Description of the subject of the contract.
