ABSTRACT:
This invention relates to an equipment for producing high-pressure saturated steam. The equipment includes a water tank, a pump, a check valve, an atomizing nozzle, a heat chamber and a steam outlet. The pump is connected between water tank and the check valve. The check valve is connected with the heat chamber via the atomizing nozzle. The heat chamber having a steam outlet is hollow into which the atomizing nozzle extends. The hollow chamber is divided into many small chambers which are connected with each other successively. The equipment can produce high temperature steam rapidly and save energy.
