Combined heat and power system for stoves with thermoelectric generators

Abstract

Solid-fuel stoves are used in developing countries, remote locations, and in general more commonly due to convenient fuel cost for space heating. The possibility of also using the stove heat to heat water and produce electricity represents an added benefit. This work presents an application of thermoelectric generators to a solid-fuel stove to concurrently charge a lead-acid battery and transfer heat to water for heating or household use. The feasibility of the proposed CHP system is demonstrated for a common solid-fuel stove. This system produces an average of 600W th and 27W el (42W el peak) during a 2-h long experiment in which the TEG efficiency is around 5% and the MPPT efficiency of the power converters used is demonstrated.

The development of a thermoelectric power generator dedicated to stove-fireplaces with heat accumulation systems

“…The solution is similar to many concepts and tested designs described in the literature such as, e.g. [20], where the TEG is directly placed in the combustion chamber and it is cooled by a water loop using a pump and a dedicated water tank. The paper [21] describes such water-cooled systems based on natural convection for the TEG.…”

Clean, efficient and affordable energy for a sustainable future

“…In paper [49], an application of thermoelectric generators to a solid-fuel stove was proposed to concurrently charge a lead-acid battery and transfer heat to water for heating or household use. The feasibility of the proposed CHP system was demonstrated for a common solid-fuel stove.…”

A two-stage approach for combined heat and power economic emission dispatch: Combining multi-objective optimization with integrated decision making

“…Furthermore, recent research suggest that CHP units are considered as an environmentally friendly syste m, since the greenhouse gas emissions can be reduced by nearly 13%~18% by making use of cogenerations [6]. 7 CHP economic dispatch (CHPED) has been recognized as an important means to achieve optimal operation for CHP systems, since it is able to significantly reduce the unit energy consumption of coal-fired power plants through optimizing the allocation of thermal and electrical load instructions. In general, the primary goal of CHPED is to minimize of the economic costs like fuel costs.…”
