Description
Latvia is importing nearly 70% of the total primary energy sources including natural gas. In the total transformation sector natural gas is used almost three times more than the local biomass. The main braking factor for more rapid growth in the use of biomass is that existing gas boilers are not suitable for burning biomass. The project aim is developing and demonstrating innovative and effective biomass gasification technology solutions (systems) that will replace imported natural gas use by local renewable energy sources (biomass) in the existing natural gas boilers. The project is intended to model processes and gas generator in order to create a module to build, test, and based on the results, adjust equipment and systems structural elements to ensure that the produced syngas could replace natural gas in the heat boiler with a capacity of at least 450 kW. The project aims to achieve the following quantitative indicators: reduction of CO2 emissions 848,400 kg per year. Efficiency ratio 2.973474 (kgCO2 /EUR per year). Project partner's main task will be the development of scientific equipment.
Summary of project results
Latvia is importing nearly 70% of the total primary energy sources including natural gas. Latvian energy sector is still too dependent on natural gas. The main braking factor for more rapid growth in the use of biomass is that existing gas boilers are not suitable for burning biomass, but a new biomass boiler requires substantial amounts of capital. Project's objective was to reduce impact on climate change by constructing and demonstrating an innovative and effective low carbon dioxide technological solution (system) for biomass gasification, which includes the main equipment (gas generator) and ancillary equipment. As a result of the biomass gasification process biomass is transformed into easily flammable mixture of gases – synthesis gas (called syngas or generator gas). This gas can be used to replace imported natural gas by local renewable energy sources (biomass) in the existing natural gas boilers without their replacement. In order to achieve the planned results technological equipment was formed for the needs of experimental research of the biomass gasification process with an aim to obtain a more efficient solution if compared to the gasifiers currently available on the market. Main activities intended to model processes and gas generator to create a module to build, test, and based on the results, adjust equipment and systems structural elements to ensure that the produced syngas could replace natural gas in the heat boiler with a capacity of at least 450 kW. Main activities were process analysis and mathematical description, technological systems and equipment sketches scheme, establishment of facility, system performance optimization and demonstration of project results. Experimental research results of the developed innovative biomass gasification technology suggest that technology operates effectively, and allows substituting the use of imported natural gas with local renewable resources. The performed measurements show that the developed innovative biomass gasification technology operates successfully, and produces syngas with a relatively high combusting heat. As the result of project activities innovative and effective low carbon biomass gasification technology solution (system) is developed and demonstrated.
