Austria aims at increasing its share of renewable energy production by 11% until 2020. Combined Heat and Power (CHP) plants fired by forest wood can significantly contribute to attaining this target. However, the spatial distribution of biomass supply and of heat demand limits the potentials of CHP production. This paper assesses CHP potentials using a mixed integer programming model that optim...

Thermochemical gasification is one of the most promising technologies for converting biomass into power, fuels and chemicals. The objectives of this study were to maximize the net energy efficiency for biomass gasification, and to estimate the cost of producing industrial gas and combined heat and power (CHP) at a feedrate of 2000kg/h. Aspen Plus-based model for gasification was combined with a...

Executive Summary Forests are expected to have an important role in climate change mitigation under future climate change policy. Currently, much of the interest in forests centers on the opportunity to sequester carbon as part of a cap and trade policy. In addition to sequestering emitted carbon, forest resources reduce carbon emissions at the source when substituted for the fossil fuels curre...

The present work investigates the matching of an advanced small scale Combined Heat and Power (CHP) Rankine cycle plant with end-user thermal and electric load. The power plant consists of a concentrated solar power field co-powered by a biomass furnace to produce steam in a Rankine cycle, with a CHP configuration. A hotel was selected as the end user due to its high thermal to electric consump...

Combined Heat and Power (CHP) production using renewable energy sources is gaining importance because of its flexibility and high-energy efficiency. Biomass materials, such as corn stover and forestry residues, are potential sources for renewable energy for CHP production. In Mississippi, approximately 4.0 MT dry tons of woody biomass is available annually for energy production. In this study, ...

Combined heat and power (CHP) plants have received a resurgence of attention from power system planners and policy makers in an effort to fully realize the potential of the technology. CHP plants that are thermal-primary, however, do not always maximize the benefits provided to the power system. In this study, we examine how power system planning metrics can be applied to CHP plants to better u...

This study assesses the potential environmental impacts related to energy valorization of agro-food industry waste thought Life Cycle Assessment methodology (ISO 14040). The system examined consists a real anaerobic digester coupled with combined and heat power plant (AD-CHP) operating in Sicily. analysis accounts for all occurring from delivery biomass AD-CHP up electricity generation CHP. mai...

This paper aims at assessing the impact of retrofitting an existing, 730 MWe, coal-fired power plant into a biomass-fired combined heat and (CHP) on its energetic exergetic performances. A comprehensive thermodynamic model was developed validated against field data, resulting in less than 1% deviation between measurements for main process parameters. The then used to predict behaviour biomass C...

PROCESSES – Biomass combustion is a carbon-free process because the resulting CO2 was previously captured by the plants being combusted. At present, biomass co-firing in modern coal power plants with efficiencies up to 45% is the most cost-effective biomass use for power generation. Due to feedstock availability issues, dedicated biomass plants for combined heat & power (CHP), are typically of ...
