Hinweis der Redaktion
- Change date at bottom of all slides DONE
- NOx: general term for oxides of nitrogen. By-product of combustion PM: small particles, solid and liwuid produced during combustion and remain suspended in flue gas and ambient air SCI contribute 40% of total PM in EU and 12% of total NOx Total number houses in country: ~1.5 million Total oil fired: 47% ~ 600,000 Total gas fired: 28% ~360,000 Pellet: Based on SEI Greener Home scheme grants, ~6000 biomass boilers installed (~0.4% of total houses with central heating) Contrib of SCI to total emissions in Europe PM: 40% NOx: 12%
- Delete this maybe? They all know what an E.I. Is .. Not sure really...
- Shorten this: Determine duty cycle Put boiler thru this in lab Combine EF with info abt total no etc DONE
- Put title on slide DONE
- Lable DLPI and Testo DONE
- EF depends strongly on fuel type, vehicle class (EURO level, SUV etc.) drive cycle
- EF depends strongly on fuel type, vehicle class (EURO level, SUV etc.) drive cycle
- Change artemis to model
- Insert references for âdoesnât correlateâ
- Why weâre different to others: Work done on pellet boilers in scandinavia but they all focussed on steady state operation of boiler. Weâre taking transients and startups into account as well. Their heating systems are designed differently to ours. They generally run for very long periods of time to provide a constant heat supply. In Ireland heating systems are designed to be used more intermittently so startup peaks are a very important contribution to our overall emission level
