Background
The concrete prefabricated part curing is usually carried out in two modes of natural curing and steam curing. Steam curing is to place the component in a curing chamber containing saturated steam or a mixture of steam and air, and cure the component in an environment of high temperature and humidity to accelerate the hardening of the concrete and make the concrete reach a specified strength standard value in a short time. In order to produce the precast concrete members in large batch, the floor area is reduced, meanwhile, the strength of the members is ensured, and at present, the low-temperature centralized steam curing mode is mainly adopted at home by taking the advanced technology abroad as a reference.

The electrode heating type steam generator utilizes the conductive property of water containing electrolyte and is heated after being electrified to generate hot water or steam. Because the resistance of water is used for directly heating, 100 percent of electric energy is converted into heat, and basically no electric energy is lost; when the boiler lacks water, the current channel between the electrodes is cut off, the phenomenon that the boiler is damaged due to water shortage does not exist like the conventional boiler, and the small-capacity low-pressure steam generator is energy-saving and safe equipment and is particularly suitable for the concrete steam curing process in the field of assembly type buildings.
