1. Fluid dynamics of circulating fluidized-bed boilers
Sammanfattning : .... LÄS MER
2. On the Design of Residential Condensing Gas Boilers
Sammanfattning : Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. LÄS MER
3. Catalytic Oxidation of Emissions from Residential Wood fired boilers
Sammanfattning : The European Commission has set a target of doubling theenergy supply from renewable sources from 6% in 1997 to 12% in2010. An increased usage of biofuels will play an importantrole in meeting this target. LÄS MER
4. Fouling in biomass fired boilers
Sammanfattning : In order to reduce the discharge of the greenhouse gas CO2, the use of biomass is nowadays promoted as fuel in boilers. Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. LÄS MER
5. Fouling in biomass fired boilers
Sammanfattning : This thesis describes a detailed investigation into fouling in biomass fired boilers according to fuel mixture, combustion conditions, transportation of particles by the flue gas and the probability of particles impinging and sticking onto heat transfer tubes. The effects of fouling on overall boiler performance and the efficacy of soot blowing are also investigated. LÄS MER
