Cogeneration and trigeneration systems have been broadly employed as part of the strategies oriented toward rational energy use. The assessment these must include simultaneous considerations costs, irreversibility, losses, their causes. This work presents a step-by-step thermoeconomic analysis microcogeneration unit, composed an internal combustion engine ammonia-water single-effect absorption ...

Abstract In co-and trigeneration plants with internal combustion engines, waste heat from their cooling system can be fed to a exchanger network for office heating, hot water production, or used in industrial processes. At the same time, care must exerted not cool return fluid below threshold, order avoid piston seizure. this work, is that of gas-engine large dairy plant Rome. Since its daily a...

Nowadays, ever-increasing energy demands and the depletion of fossil fuels require efficient environmentally friendly technologies for generation. In this context, systems integration makes a very strong proposition since it results in saving, fuel diversification, supply cleaner energy. To end, is utmost importance to realize current developments field portray state art renewable generation in...

The operation of coal mines is intricately linked with emitting a large quantity mine methane, and in most cases, this methane releases into the atmosphere. In total, according to statistics, mining enterprises emit 8% anthropogenic determining contribution greenhouse gas emissions amount 17%. There are various means for utilization. study, concept “Coal-Energy-Information” proposed. This impli...
