Heat Recovery System from the exhaust of the K6 biomass boiler in the Białystok Co-Generation Plant

On 23 February this year, Jan Olsson, Ambassador for Ecology of the Swedish Government and representative of the Embassy of Sweden, participated in the official hand-over of the Heat Recovery System from the exhaust of the K6 biomass boiler in the Białystok Co-Generation Plant. The ceremony was also attended by the investor, the representatives of the consortium executing the project, the authorities and the mass media.

The Heat Recovery System in the Co-Generation Plant is the first Polish installation of heat recovery from wet exhaust. The installation allows for saving energy that was previously lost in the atmosphere, in the form of exhaust gases discharged by chimneys, and will increase co-generation of heat by reducing so-called “exhaust loss.” Recovery of energy consists in collection of moisture condensation heat contained in exhaust gas and its transfer to the heat distribution network. The nominal capacity of the installation is 18.4 MW. The estimated annual heat production is 385,697 GJ. The innovative technology applied in Poland has been successfully applied in Scandinavian countries in waste incineration plants and biomass-heated boilers.

“The Heat Recovery System from the exhaust of the K6 biomass boiler in the Białystok Co-Generation Plant is a pro-environmental installation designed according to the innovative technology of our Swedish partner, the first investment of this type in Poland. Taking into account the satisfaction expressed by the Employer from the implemented investment and positive measurement results of guaranteed parameters – the heat recovery established in the agreement at the level of 18.69 MW was exceeded by approx. 10% - there is a chance that similar environmentally-friendly installations will be built in other places in Poland” said Jose Angel Andres Lopez, Vice-President of the Board in charge of the Production Department in Mostostal Warszawa SA.

Depending on operating conditions, the heat recovery system operates with a heating capacity amounting to 10–18 MW. Depending on the installation’s time of operation, in the course of a year it allows for producing 175,000 – 385,000 GJ of heat without the necessity of additional fuel input. In the winter period, the heat from the system will help reduce coal consumption in the existing boilers, which will contribute to the reduction of CO2 emission to the atmosphere. The estimated reduction in carbon dioxide emission amounts to approx. 20,000 tonnes per year.
