Autoclave for AAC plant is large pressure vessel for steam curing, has excellent thermal insulating quality, and it supporting the use of steam boilers. The autoclave is a horizontal cylinder device, when curing the aerated concrete, there is hydrothermal reaction (CaO-SiO2-H2O) happened in autoclave. It has the advantages of wide applicability, good treat efficiency, large capacity, reasonable layout, and safety operation, etc. Devotion Boiler could design and manufacture various forms of autoclave according to customers’ requirements. Except AAC plant, the autoclave could also be used for wood preservation, maintenance and steaming of lime-sand brick, fly-ash brick, new light wall material, concrete tubular pile and other building products, moreover, it can used for the products steaming in chemical industry, medicine, rubber, wood corrosion prevention, gypsum, glass, thermal insulation materials, textile, war industry and other area.
