Industrial Autoclave Boiler AAC Curing Equipment for Concrete Block Production

The Industrial Autoclave is a large pressure vessel that cures AAC blocks with saturated steam at high temperature and pressure, giving them their final strength and dimensional stability. Loaded moulds or cars of green blocks are wheeled into the cylindrical autoclave, the door is sealed and steam is admitted to raise the internal pressure and temperature to the set point for a controlled curing cycle. The strong, precisely fabricated shell and reliable door seal hold the pressure safely, while insulation limits heat loss and steam consumption. Available in a range of sizes and pressure ratings, the autoclave is the key curing stage of every AAC production line.

• High-Pressure Steam Curing: Saturated steam at up to 1.65 MPa and 205 degrees Celsius cures the blocks to full strength safely and consistently.
• Strong Fabricated Shell: The cylindrical shell and ends are fabricated to pressure-vessel standards, holding pressure safely in continuous daily cycling.
• Reliable Door Seal: A robust, well-sealed door holds pressure during curing and opens quickly for efficient loading and unloading.
• Efficient Insulation: Insulation on the shell limits heat loss, reducing steam consumption and energy cost while keeping curing uniform.
• Controlled Curing Cycle: Pressure, temperature and time are precisely controlled to achieve the required block strength batch after batch.
• Range of Sizes: Models from 2x21 m to 2.85x39 m suit different line capacities and plant layouts.

Industrial autoclaves are used in AAC plants to steam-cure aerated concrete blocks and panels, and in the production of sand-lime brick, calcium silicate products and other autoclaved building materials. They are also applied in chemical, rubber and wood treatment processes requiring controlled high-pressure steam curing.

The autoclave is shipped in sections with the shell ends and openings protected, and the door, valves and instruments crated separately. A full set of drawings, a pressure-test report and an operating manual are provided, and each vessel is inspected before dispatch. We provide a twelve-month warranty and dependable service for doors, seals and pressure fittings to keep your curing system safe and reliable.
