Waste fired boilers have low electricity production efficiency compared to biomass fired boilers and above all compared to coal fired power boilers. This is due to the highly corrosive environment resulting from waste incineration.
The project goal is to do a full-scale test and to evaluate an innovative cleaning system for waste incineration plants. The new technology,”sulphur recirculation”, significantly reduces the corrosion in the boiler without dosing new, external sulphur. The effect will be reduced life cycle costs and the possibility to increase the electricity production efficiency. The process ”sulphur recirculation” derives from several years of development within Götaverken Miljö as well as from results of pilot testing at a 0,5 MW waste boiler. The pilot tests also showed a reduced dioxin formation. This project aims at investigating the last remaining parts of the development work - a full-scale verification before the system can be commercialized.
If successful, the characteristics of the technology are lower corrosion rate and reduced dioxin formation. The effects will be reduced life cycle costs and to enable the increase of electricity production efficiency.
