Aerated concrete is a lightweight porous silicate product made from siliceous materials (sand, fly ash, and silicon containing tailings) and calcareous materials (lime, cement) as the main raw materials, with the addition of an air entraining agent (aluminum powder) through processes such as batching, mixing, pouring, pre curing, cutting, steaming, and curing. It is called aerated concrete because it contains a large number of uniform and small pores after being aerated. The steam curing process is an important step in high-pressure steam curing of aerated concrete bodies. Steaming and curing operations have a direct impact on the yield of finished products. The curing of concrete requires a suitable temperature environment. Steam boilers can convert water into a large amount of steam through fuel (such as natural gas, diesel, etc.) or the use of electrical energy, rapidly increasing the temperature and humidity of the concrete curing environment. The application of steam during the curing process is crucial to ensure that the concrete gradually reaches the required strength and durability. A professional manufacturer of concrete and prestressed concrete components in Kazakhstan introduced a 2 ton of WNS series gas fired steam boiler provided by Xinli Boiler to its production process in order to further improve production efficiency and product quality.

This kind of WNS series gas fired steam boiler from Xinli Boiler can provide stable and uniform steam supply for concrete curing with efficient heat exchange performance, which can ensure the balance of moisture and temperature in the formation process of concrete components. This helps to improve the quality of finished concrete products. During the curing process of concrete, high-quality steam can more effectively promote the internal hydration reaction of concrete. This is the key to ensuring that concrete achieves the expected strength and durability. Xinli Boiler's WNS series gas fired steam boiler produces steam with high temperature stability and cleanliness. It can avoid surface defects such as pores and cracks that may be caused by poor steam quality in concrete, thereby significantly improving yield and safety performance. The boiler has an advanced control system equipped with control, alarm and interlocking devices for boiler water level and steam pressure, which can ensure the safe running of the boiler. In addition, the aerated concrete industry will have a large amount of condensed water recycling. Xinli Boiler's technical team can help enterprises reduce exhaust gas temperature by equipping boilers with air preheaters and energy-saving devices, thereby achieving the goal of energy conservation and emission reduction.
