A steam generator has two sections 3,4 separated by a wall 13 through which finned heat pipes 1 in circular rows pass, the heat pipes 1 having one end in an exhaust flow in a vertical cylindrical space 2 of section 3 and the other end in water/steam in section 4, each heat pipe independently drawing in heat from the exhaust and transferring it to the water/steam. Exhaust inlet 5 of section 3 and outlet 26 of section 4 are on the same vertical axis, with exhaust gas flow radially through the heat pipes 1 being controlled by a baffle 9 and butterfly valve 10. Each heat pipe 1 is fixed to the wall 13 with a welded collar (29, fig 6), threaded nut and gasket or O-ring, and guided in holes in a bottom plate 15. Water is fed to the steam space by nozzles 25 in a ring shaped tube 24. Panels of the exhaust flow section 3 may be removable.
