Electrical Power Output

Solar pond is one source of renewable thermal energy. The solar pond collects and stores thermal energy at the lower zone of the solar pond. The temperature at the lower zone can reach up to 90 °C. The solar pond is capable storing thermal energy for a long period. The stored thermal energy can be converted into electricity by using thermoelectric generators. These thermoelectric generators can be operated using the cold and hot zones from a solar pond. In this paper, the experimental investigation of power generation from the solar pond using thermoelectric generator and simple heat exchanger is discussed. A maximum of 7.02 W of electrical power output was obtained from a simple heat exchanger with 40 thermoelectric modules.

This paper presents a method for calculating the electrical power generated by a thermoelectric heat exchanger. The thermoelectric heat exchanger transfers heat from a hot fluid to a cold fluid through a thermoelectric generator located in the heat-exchanger wall separating the two fluid streams. The method presented here is an extension of the NTU method used to calculate heat-exchanger heat-transfer effectiveness. The effectiveness of thermoelectric power generation is expressed as the ratio of the actual power generated to the power that would be generated if the entire heat-exchanger area were operating at the inlet fluid temperatures. This method collapses results for several heat-exchanger configurations and allows a concise presentation of the results. It is shown that the NTU method of calculating heat-exchanger heat-transfer effectiveness can be modified in a similar way.

Rocketdyne is under contract to the Department of Energy for the development of heat exchanger technology that will allow coal to be burned for power generation and cogeneration applications. This effort involves both atmospheric fluidized bed and pulverized coal combustion systems. In addition, the heat exchanger designs cover both metallic and ceramic materials for high-temperature operations. This paper reports on the laboratory and small AFB test results completed to date. It also covers the design and installation of a 6×6 ft atmospheric fluidized bed test facility being used to correlate and expand the knowledge gained from the initial tests. The paper concludes by showing the direction this technology is taking and outlining the steps to follow in subsequent programs.

New System

A new system for converting combustion heat into electric power was proposed on the basis of countercurrent burner with thermoelectric element embedded in a wall separating incoming fresh mixture and combustion products. The wall serves as heat exchanger between combustion products and the fresh mixture. Numerical simulations showed that almost whole combustion heat may be transferred through the thermoelectric element in such system and the total thermal efficiency attained a value close to the conversion efficiency of the thermoelectric device itself.
