Abstract:
Biomass as an energy source (wood, wood chips) is widely considered as an alternative and relatively renewable energy source. Given calorific value of wood wide availability and relatively low harmful emissions, with proper regulation and effective burning process, it becomes great energy source which can limit energy dependency and bear lower effect on climate. Solid biomass boiler and power plants have greatly improved in efficiency with implementation of flue gas condensing economizers (FGC), raising biomass energy plants efficiency in combination with district heating systems. However, using district heating limits the amount of flue gas utilization after the combustion process and relies greatly on DH return temperatures which defines how much energy can be recovered from biomass flue gas, which also limits how much the flue gas can be condensed. In this article the possibility of further flue gas cooling means is evaluated, experimenting and simulating subcooling flue gas well below dew point (50°C) using novel heat exchanger made with corrugated stainless steel pipes and corrugated plastic tubes.
