Title: Pure steam generator
Inventor: ENOMURA SHINICHI
IPC: F22B1/16
Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a pure steam generator which prevents water leakage and liquefaction of a portion of generated steam due to cooling. SOLUTION: A heating tube 1 is formed so as to have a spiral shape and be extensible like a coiled spring. Accordingly, the influence of the stress that has been generated by the expansion of the tube due to temperature difference can be suppressed. Further, as the feedwater and the pure steam each form a completely separate channel, the surroundings of the joints between the heating tube 1 and steam generating tubes 2, etc., 2, and a shell 3 do not have to suffer from cross contamination ascribed to water leakage, and liquefaction of steam due to cooling can be prevented. With the compact structure, the pure steam generator exerts a good heating efficiency.
