1. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass
Abstract : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. READ MORE

2. Deposit formation in the grate-kiln process
Abstract : Deposit formation in the grate-kiln process is a challenge for the iron ore pellet production industry. The deposits cause disturbances that affect the production capacity of the pelletizing plant. READ MORE

3. Mechanisms of Deposit formation in the Grate-kiln Process
Abstract : Fly ash particles from the combustion of coal together with disintegrated particles arising from iron-ore pellets result in accumulation of deposits on the refractory linings of the grate-kiln induration machine during the iron-ore pelletizing process. Deposit formation gives rise to decreased production efficiency, unscheduled shutdowns, high cleaning costs, and equipment failures. READ MORE

4. NOx Formation in Rotary Kilns for Iron Ore Pelletization
Abstract : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. READ MORE

5. Drying and Pyrolysis of Logs of Wood
Abstract : This work concerns log firing in small-scale boilers for house heating, which in Sweden meets a heat demand of 12 TWh a year. In boilers used for domestic central heating in the sizes of 10 to 30 kW the predominant combustion technique is grate firing. READ MORE
