Fresh autoclaved aerated concrete mixes enter the autoclaves in the form of a cake (known as green cake) and after curing for a certain time period under certain pressure, the material hardens and thus reaches its final strength. Generally, the internal steam pressure of these autoclaves is approx. 12 Bar, and depending on this steam pressure, the internal temperature is around 192°C. Homogeneous heat distribution is very important for processing. The autoclave must provide homogeneous heat transfer based on the maximum green cake load, and the condensate associated with the heat transfer must be evacuated as soon as possible. Correct positioning of internal piping, welding points, steam supply, vacuum and condensate lines, and inlet & outlet nozzles, as well as correct installation, must be designed correctly according to process requirements. Also, a correct design increases production performance and the visual quality of the final product. If the nozzles are not positioned precisely, surface defects and/or yellow-discoloured blocks will affect the white and pure surface appearance of the product.  Devamını oku…
