Abstract

This paper presents studies carried out in a pilot-scale plant for recovery of waste heat from a flue gas which has been built in a lignite-fired power plant. The purpose of the studies was to check the operation of the heat recovery system in a pilot scale, while the purpose of the plant was recovery of waste heat from the flue gas in the form of hot water with a temperature of approx. 90 °C. The main part of the test rig was a condensing heat exchanger designed and built on the basis of laboratory tests conducted by the authors of this paper. Tests conducted on the pilot-scale plant concerned the thermal and flow parameters of the condensing heat exchanger as well as the impact of the volumetric flow rate of the flue gas and the cooling water on the heat flux recovered. Results show that the system with a condensing heat exchanger for recovery of low-temperature waste heat from the flue gas enables the recovery of much higher heat flux as compared with conventional systems without a condensing heat exchanger.

Abstract

The paper presents a synthesis of approaches to development and functioning of Functional Urban Areas. The authors present typology of such areas and determine how they facilitate the flow of various types of potentials, paying particular attention to creativity and innovations. The emphasis is put particularly on non-spatial factors of development of such areas. The process of forming the functional area basing on common strategy of development founded on various types of potentials is presented on two examples.
