“…Thermal conductivity and preheating efficiency affect each other. Figure 10a-c shows temperature distributions in the reaction zones axis in the combustors with different wall materials [83]. From Figure 11a-d, it can be concluded that the reaction zone temperature will increase and the influence on the hot spots is more significant when the wall thermal conductivity reduces.…”

“…The phenomenon will occur when lots of heat in the combustor is removed at a high rate [78,79], or coupled to a strong endothermic reaction [80,81]. On the contrary, if the micro-system is coupled to the external heat source [82] or is an adiabatic [83], the conversion will be improved at the expense of hot spots. Thus, material choice is very important for combustors.…”

With the improvement and development of micro-mechanical manufacturing technology, people can produce an increasing variety of micro-electromechanical systems in recent years, such as micro-satellite thrusters, micro-sensors, micro-aircrafts, micro-medical devices, micro-pumps, and micro-motors. At present, these micro-mechatronic systems are driven by traditional energy power systems, but these traditional energy power systems have such disadvantages as short endurance time, large size, and low energy density. Therefore, efforts were made to study micro-energy dynamical systems with small size, light gravity, high density and energy, and long duration so as to provide continuous and reliable power for these systems. In general, the micro-thermal photoelectric system not only has a simple structure, but also no moving parts. The micro-thermal photoelectric system is a micro-energy power system with good application prospects at present. However, as one of the most important structural components of micro-thermal photoelectric systems, the microburner, is the key to realize the conversion of fuel chemical energy to electric energy in micro-thermal photoelectric system. The studies of how to improve the flame stability and combustion efficiency are very necessary and interesting. Thus, some methods to improve the performance of micro-burners were introduced and summarized systematically, hoping to bring some convenience to researchers in the field.

“…These modules when used within the required temperature range can be used to power basic domestic appliances and reduce the over dependence on the national grid. They are known to be noiseless in operation as they contain no moving parts, require little or no maintenance and are highly reliable with a long-life span [3], other advantages are their small sizes, simple mode of operation and they are environmentally friendly [1]. In order to safeguard and prolong the lifespan of the thermocouples temperature control measures must be adopted.…”

“…Singh et al [3] studied the development and investigation of a non-catalytic self-aspirating mesoscale premixed burner integrated thermoelectric power generator. The research was divided into two phases with the first phase concerned with optimization of the burner design in order to achieve a stable enclosed premixed flame and from the results obtained it could be concluded that the introduction of a premix zone and backward facing step in the gas burner design enhanced the mixing of reactants (propane and oxygen) thereby improving combustion and overall temperature.…”

A thermoelectric generator consists of various thermocouples arranged in series. A voltage is generated when a temperature gradient exists across the junctions of the thermocouples. This research modelled, developed and tested a thermoelectric generator with hot side temperature control using propane gas, in a microcontroller integrated development environment to protect the modules from excessive high temperatures. The models were solved using MAT-LAB for pictorial representation of the performance of the generator with temperature gradient, hot and cold side temperatures. The thermoelectric generator was developed using ten SP-184827145-SA modules. The temperature control circuitry consists of an ATMEGA32 microcontroller, DS18B30 temperature sensors, stepper motor, computer interface and power supply unit whose sole aim is to regulate the gas supply and hence control the flame temperature. The maximum open circuit voltage gotten was 25 V at 300 secs with hot side temperature of 120°C and cold side temperature 30°C, with an efficiency of 3.6%. It was also found out that the higher the temperature gradient the higher the voltage produced.
