Do not arbitrarily change the raw material parameters built-burning machine, and often need to use the concept of the crater to observe the pellet fuel combustion in the furnace of life, to prevent negative phenomena. The method of biomass particles with the view to reduce the aluminum slag combustor

Biomass particles to reduce the aluminum slag combustor method
Aluminum and aluminum alloys not only high chemical activity, and its melt flowability is excellent. Aluminum melt viscosity at 750 ℃ ​​viscosity of water at 20 ℃ very close, which is the main reason for its easy penetration and chemical reaction to the interior lining. When the molten aluminum with the reaction between the refractory lining not only the product quality is affected, but also the lining surface nodules, ridges and precipitated debris by liquid aluminum interface and immersed portion of the original tile risk of occurrence of cracks, shutdown also cause peeling. Therefore, the lining material with the molten aluminum in contact, must have a high chemical stability and a minimal amount of impregnation. Thus, the aluminum smelting process, with increasing slag weight, the aluminum melt loss also increased, and the number and amount of slag melting temperature, charge status, and other factors related to the production process. Measures to reduce the biomass particles combustor aluminum slag: 1, the furnace geometry and reasonable order of addition; 2, strict control of the melting temperature to prevent overheating, the flame jet should be a certain angle, for rapid melting, shorten the melting time; 3, suitable dosage melting and refining time, stirring to smooth the surface of the melt does not destroy the oxide film, the timely coverage of the aluminum melt; 4, for aluminum scrap sorting, washing, large specific surface area of ​​the finely divided charge baling press; 5, former slag slag processing
