Abstract
To optimise pulverized peat combustion it is necessary to sort out the influence from parameters like particle size and fuel moisture content on ignition and burnout. Peat contains significant amounts of sulphur but the ash is often rich in calcium and alkaline which can absorb some of it. The influence of combustion and fuel parameters on SO{sub 2}-as well as NO{sub x}-emission is important to clarify. Four different swedish peat qualities were originally included in the study. As one of them was not available, a Finnish briquettized peat was used to study the pretreatment on the milling. Pulverized coal was used as a reference fuel. The experimental equipment consisted of a crusher, a drier and a hammer mill for pulverization. The experimental furnace was a plug-flow reactor with a pre-mix burner. Some of the results were: At equal moisture content there were less fines (<100 {mu}m) from the briquettized peat than from the Swedish peat due to shorter residence time in the mill. Both moisture content and particle size distribution had a significant influence on ignition time. Dry, finely milled peat had an ignition delay of about 20 ms and the moist peat with a high amount of coarse particles
