Integration of waste heat streams into industrial chps or district heating units

The European Horizon 2020 project [1] FLEXCHX aims to develop a flexible and integrated hybrid process combining electrolysis of water with gasification of biomass and catalytic liquefaction. This hybrid concept might allow more flexible and fast response to changes in consumer heat demand and might capable of managing the energy system fluctuations on an hourly and daily basis. In addition, the gasification and FT process concept has many designs and operation alternatives, therefore in order to develop a flexible hybrid process combining electrolysis, there was evaluated different operating modes and conditions at which some amount of by-product heat is generated. In this purpose, there was performed an analysis of the selected energy object integrated into the district heating system presenting the structure and regulation of the Lithuanian energy market. The basic aim of this work is to assess qualitatively the various potential district heating and industrial CHP applications where the waste streams may be integrated according to the heat and power markets. This work provides data for the surrounding conditions of FLEXCHX process in the present CHP system and possibilities of integration variations.
