Lagring och förbränning vid gårdsproduktion
Biogas har anva?nts som fordonsbra?nsle i Sverige sedan början av 90-talet som ett förnyelsebart alternativ till naturgas. Först till bussflottor och sedan slutet av 90-talet a?ven till personbilar. Biogasproduktionen i Sverige har sedan slutet av 90-talet varit omkring 1,5 TWh …
Stegen till att eliminera radongas med rätt Grundläggningsmetod
… how this problem is seen globally. International studies show that radon gas in indoor air increases the risk of getting lung cancer. By 2020, all single-family homes and public facilities must be remediated to a statutory value annual average level. It is one of sixteen …
SAMMANFATTNING Lackage fran en komponent i form av vatska eller gas ar ett ofta underskattat problem som kan ge upphov till samre produktkvalitet, energiforluster och i slutandan ge ekonomiska konsekvenser om lackaget blir for stort. Det finns dessutom en miljo- och halsorisk om …
tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
… and compared to a reference scenario with heat production fueled with natural gas. The study found that there is a considerable decrease in greenhouse gas emissions when using wood fuel instead of natural gas, but there is a slight increase in the eutrophication and …
… aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which …
