Abstract

939,726. Vertical steam boilers. A. HUET. Jan. 4, 1960 [Jan. 2, 1959; Jan. 14, 1959; Feb. 13, 1959; March 17, 1959; March 19, 1959], No. 271/60. Class 123(2). A steam boiler heated by a hot fluid, for example, the gaseous coolant from a nuclear reactor, comprises an elongated housing, an inlet duct at one end thereof for the heating fluid, a sleeve lining part of the housing and sealed at one end to the inlet duct, the sleeve extending away from the one end of the housing and serving to separate an inner heating fluid flow path from an outer annular coolant flow path, thus protecting the inlet end of the housing from contact with the hottest fluid. In the form shown in Fig. 1, the housing comprises a cylindrical casing a closed by a dome b having a hot gas inlet c and containing steam generating means of which only the superheater d and the top of the evaporator e are shown. The inlet duct c terminates in a Venturi p to the outside of which a sleeve o sealed. In use, the main flow of heating fluid passes over the superheater to the evaporator. Openings q are provided in the Venturi throat and the effect of the Venturi draws a minor proportion of the fluid, partially cooled by contact with the superheater, up through the annular space between the sleeve and the casing to cool the latter. Water tubes r may be located in the annulus and the dome b may be covered with water tubes s to provide additional cooling. In a modification, Figs. 4 to 6 (not shown), the lower edge of the sleeve o extends into a circular U-section trough secured to the casing, the trough, which may contain further water heating tubes, serving to divert an increased proportion of the main gas flow into the annulus. In a further modification, Fig. 3 (not shown), a part of the fully cooled gas leaving the casing is recirculated by a fan to the annulus and to an outer annulus between the upper part of the casing and a surrounding sheath. In a further modification a Venturi establishes the flow in the inner annulus as in Fig. 1 whilst the outer annulus is supplied with gas by a fan.
