Save Energy

The technological developments in the steam boiler field, induced by changes in the use of different fins and the need to save energy, has its consequential effects on the heat transfer techniques. As the extended surface tube is one of the important components of the steam boilers and particularly of waste heat recovery boilers (WHRB) behind turbines, we want to draw the attention to recent developments in the field of finned tubes, opening new possibilities for the optimization of construction costs of WHRB on one hand and reducing the fouling problem by a new geometry of the helically wound fins on the other hand.

Abstract Waste heat recovery from power plants and industries requires a new type of electricity generators and related technological developments. The current research work is aimed at the design of a multi-kilowatt thermoacoustic electric generator, which can be employed as the bottoming cycle of a gas-turbine power plant or for industrial waste heat recovery. The proposed device converts thermal energy into acoustic power and subsequently uses a piezoelectric alternator to convert acoustic power into electricity. The challenge in designing such a device is that it has to be acoustically balanced and the performance of the device is greatly affected by numerous parameters such as frequency of the traveling acoustic wave, heat exchanger parameters, regenerator dimensions, acoustic feedback loop, etc. The proposed device is a lab-scale demonstration targeted to produce a few kilowatts of electric power from a 20 kWth heat source. To achieve the acoustically balanced configuration of the device, DeltaEC software is used. The DeltaEC model outcomes are used to arrive at the optimized design of the device and its components. The analytical method, the optimized geometrical dimensions of thermoacoustic components and the minimum required conditions of heat source input are presented in this paper.
