Optimal combined heat-and-power plant for a low-temperature geothermal source

Designing an Optimal System of Combined Heat, Cold and Power for a Building

In this study, supply electrical, heating and cooling loads in the building by a separate production system and a cogeneration system, particle swarm optimization algorithm in five different scenarios were studied and analyzed (For example, Data and Information a high-rise building base 72, in the city of Kerman is used). The results show that, cold and heat power system of micro gas turbine wi...

A numerical analysis of a composition-adjustable Kalina cycle power plant for power generation from low-temperature geothermal sources

The Kalina cycle is believed to be one of the most promising technologies for power generation from low temperature heat sources such as geothermal energy. So far, most Kalina cycle power plants are designed with a working fluid mixture having a fixed composition, and thus normally operate at a fixed condensing temperature. However, the ambient temperature (i.e., heat sink) varies over a large ...

Street-heat: Controlling road temperature via low enthalpy geothermal energy

In this paper, the authors present an idea to exploit low enthalpy geothermal energy in order to reduce street temperature fluctuations throughout the year and avoid ice formation during the winter season. The key aspect of the proposed system is that it is based on the exploitation of geothermal temperature gradients through materials with high thermal conductivity inserted into the ground, su...

Modeling of a Geothermal Cycle Condenser in a Combined Diesel Power Cycle: Case Study of 42 MW Diesel Power Plant in Moghan and Ardabil

This paper presents the results of a research into the feasibility of recovering waste heat and determining design parameters of a recovery boiler for a set of medium-speed diesel generators with a capacity of 7 MW (the nominal capacity of all units is 42 MW, which would be a study on a unit). And is used to generate electricity. The main purpose of this study is to design a thermal waste recov...
