If the biomass burner equipment in the work process or uneven bottom insufficient ventilation accessories, it can easily lead to abnormal combustion machine appears, how do? With the view of a biomass gasifier refractory lined burner selection
Biomass gasifier refractory lined burner selection
Type biomass gasification burners have a lot, the main reverberatory furnace, induction furnace etc., damage the furnace lining main body of molten aluminum infiltration and erosion thereof with clay brick lining of the body, corundum alumina and mullite firebrick brick building, is also useful and high alumina castable refractory liner may be made of plastic, since the conditions are good, a longer life of the furnace. First, that the reverberatory furnace refractories, reverberatory furnace is divided into fixed and tilting using heavy oil or gas as fuel. A fixed smelting aluminum reverberatory furnace, inoperative masonry refractory fiber felt layer and insulating firebrick of clay, the bath portion over the active layer of masonry bricks, can also be used high alumina castable or preform . The working layer to the bath using a different technique, the material is different, using Al2O3 content above 75% high alumina refractory brick masonry, or more, can also be used outside the Al2O3 content of 80% high alumina castable watering integral working layer, when melting high-purity aluminum, the bath is preferable to the working layer of high purity mullite bricks, zircon corundum brick or brick building. The discharge port of aluminum, aluminum tank and stream lining of the body, to resist corrosion and infiltration of molten aluminum, the use of large silicon carbide brick building. Then the induction furnace refractories, generally with high alumina refractory brick masonry brick or three. Sometimes bottom first with a high alumina castable watering the grass, and then assemble aluminous refractory bricks. Induction furnace capacity is less than 10t, which supporting member can be used Al2O3 content of about 75% high alumina castable refractory ramming mixes or production, can also be used corundum castable refractory material or dry vibration. Lining a furnace body around the inductor coil, made of corundum refractory castable entire watering. Trough induction furnace shell lining body shop of 10mm refractory fiber felt or asbestos, insulating firebrick of clay then masonry or brick Cenosphere adiabatic layer; active layer and a coil supporting member around the commonly used refractory ramming mix the clay tamping system, also available fireclay refractory castable poured on-site, the working layer of a large channel-shaped induction furnace can also be used Al2O3 content of greater than 55% high alumina refractory brick masonry. Pool resistance heating furnace inoperative layer insulating firebrick of clay, brick or insulating panels Cenosphere masonry. May also be a bulk density of 0.8g / cm3 overall lightweight refractory castable watering; puddle working layer using Al2O3 content of about 80% high alumina refractory brick masonry, it may also be a bulk density of 2.4g / cm3 high aluminum pouring castable refractory fire. Above the bath with a portion of the active layer typically refractory castable or brick masonry preform, may also be used high alumina refractory ramming plastic. Gas hearth furnace hearth furnace wall and roof components. It may also be used in combination with reflective aluminum smelting furnace. Its lining is made of clay and high alumina refractory bricks. Aluminum refining furnace with magnesia brick masonry groove walls, with the remaining parts of refractory bricks and alumina, the electrolysis, the bath temperature is generally 720-800 deg.] C, low operating temperatures, and therefore a longer service life.
