Summary Enhancement of efficiency in rice processing mills can help rural farmers to reduce the cost of rice production. Parboiling‐the hydrothermal treatment of paddy rice, accounts for a significant portion of total rice processing costs and its quality. A rice husk powered gasifier‐based parboiling system is an attractive option for rural rice processing mills but has not been widely adopted due to various constraints. Hence, there is a need for technical and economical analysis on gasifier‐based rice parboiling system to generate information on efficiency improvement and the cost‐effective ways in rice processing industries. This paper presents a techno‐economic evaluation of rice husk powered gasifier‐based rice processing systems working in either Producer Gas in Hot Gas Mode (PG‐HGM) or Producer Gas in Cold Gas Mode (PG‐CGM). MATLAB software has been used for mathematical analysis. The research reveals that the biomass gasifier operated rice parboiling system working in both modes can have the overall system efficiency as 49% to 57% with a lowest payback time of 4‐2 years. Positive Net Present Cost is observed for the capacities above 1.5 tons/batch in PG‐HGM.

“…The exergoeconomic factor ( f k ) is the ratio of initial investment to operation and maintenance cost, which measures the impact on the system. The value of exergoeconomic factor is proportional to its influence on the system, that is, the greater the ratio, the greater the impact on the system [21]. It is calculated as follows:…”

“…The most serviceable way to increase the cost effectiveness of the system is to grasp the source of inefficiencies cost, which is very beneficial to reduce the production cost of the system. Some studies were to present a clearer picture of the main irreversibility and their corresponding costs and to find some effective alternatives to improve the efficiency and cost-effectiveness [16][17][18][19][20][21]. The application examples of this kind of multi-effect power plant include the combination of gas turbine cycle and pressurized water reactor power plant, and the combined cycle with co-firing of biomass and natural gas, which can improve the efficiency of the power plant [17,22].…”

The purpose of this paper is to improve the utilization of renewable energy by exergy and exergoeconomic analysis of the novel combined cooling, heating, and power (CCHP) system, which is based on solar thermal biomass gasification. The source of heat to assist biomass and steam gasification is the solar heat collected by a dish collector, and the product gas being fuel that drives the internal combustion engine to generate electricity and then to produce chilled/hot water by a waste heat unitization system. The analysis and calculation of the exergy loss and exergy efficiency of each component reveal the irreversibility in the heating and cooling conditions. Then, the exergoeconomic costs of multi-products such as electricity, chilled water, heating water, and domestic hot water are calculated by using the cost allocation method based on energy level. The influencing factors of the unit exergy cost of products are evaluated by sensitivity analysis, such as initial investment cost, biomass cost, service life, interest rate, and operating time coefficient. The results reveal that the internal combustion engine takes up 49.2% of the total exergy loss, and the most effective method of products cost allocation is the exergoeconomic method based on energy level and conforms to the principle of high energy level with high cost.

“…Exergoeconomic analysis is the mainstream of biomass based system. Wang and Mao (2015) show that the biomass price greatly influence the product unit cost and the exergy cost of cooling water is the most sensitive among all the demand. However, the comparison of environmental and energy benefits between biomass powered CCHP system and conventional one has not been investigated sufficiently.…”

Microgrid combined cooling, heating and power energy systems are under intensive investigation owing to expansion of renewable energy generation and development of advanced technologies in distributed energy generation. Multi-generation systems serve as one of the core parts in any microgrid energy systems. This review paper presents the summary of state-of-the-art technologies in these multi-generation systems. The first part introduces the energy structure based on energy sources and the latest renewable energy harvesting technologies for solar, biomass and geothermal energy. In the second part, prime movers, including small-scale ones used in a microgrid energy system, are summarized. The third part shows the expanded microgrid system configurations mainly for desalination. The fourth part describes the control and operation strategies for complex multi-generation systems. In the first three parts, insufficient investigation or research gaps are also pointed out. Overall, this paper systematically summaries recent progress in microgrid multigeneration system, and suggest future researches for designing and optimizing a microgrid energy system.
