Integration of Solar Energy Supported Biomass Combustion System into Individual Heating System and Evaluation of Its Performance
Project no. 22696 · Status: Kapanmış (Yayın bekleniyor) · 2021
Summary
<p>The energy sector is the largest source of emissions in Turkey, with the widespread use of fossil fuels in electricity generation, heating, and transportation accounting for a significant portion of total greenhouse gas emissions. Inefficient use of fossil fuels for heating, in particular, leads to both high heating costs and contributes to urban air pollution and global warming. In line with Turkey's 2053 net-zero emission target, green transformation in heating is essential for achieving sustainability. The integration of renewable energy sources such as solar, biomass, and wind is seen as a critical step in mitigating climate change. Within the scope of the BAP-ÖNAP project, the integration of solar thermal and photovoltaic systems with the 40 kWth capacity bubbling fluidized bed (BFB) biomass combustion system at the Solar Energy Institute has been targeted. In this context, two closed spaces of 21 m² were provided, and 4 flat-plate solar collectors were installed above. The energy from the hot fluid (hot water) coming from the solar collectors and the energy from the fluid in the BFB combustion system were separately transferred to a third fluid via a heat exchanger (boiler) and used for heating these spaces. Additionally, the BFB combustion system was integrated with a 10 kWp photovoltaic system, supplying part of the energy required by the auxiliary equipment (fans and pumps). During the project, several improvements were made to the BFB combustion system, and successful combustion and space heating trials were conducted using poultry litter as fuel. The integrated system was regularly monitored, with necessary measurements taken and evaluated from a technical perspective. Thus, a highefficiency production model that utilizes waste was established. The system has been analyzed in terms of energy efficiency, environmental impacts, and economic feasibility, with recommendations provided for the integration model. The pilot-scale heating system, which utilizes hybrid solar and biomass energy, is expected to fill a significant gap in the country.</p><p><br></p><p>Keywords: Biomass and waste combustion, solar thermal, photovoltaic, energy, environment, economy. </p>
