1. Disturbances in Fixed-Bed Combustion
Abstract : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. READ MORE

2. Modelling of biofuel combustion in fixed beds
Abstract : Fixed bed combustion is common is small to medium scale heat production in grate furnaces and domestic boilers. Modelling of these fuel beds can give a better understanding of the conversion process inside them, and provide a tool for analyzing the performance of furnaces and problems related to the fuel bed.

3. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion
Abstract : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.

5. Slag formation in fixed bed combustion of phosphorus-poor biomass
Abstract : To handle a great demand for biomass, alternative biomasses beyond stem wood are being introduced into the solid fuel combustion market, fuels with generally higher (>0,5 wt-%) ash content and different fuel ash compositions compared to stem wood, such as forest residue, bark, grass and straw. Unfortunately, combustion of these alternative fuels often causes more ash related problems such as fouling, slagging and higher particle emissions compared to combustion of stem wood. READ MORE
