Three-position actuator and apparatus incorporating same

An actuator comprises a piston and cylinder in which the piston is biased axially inwardly of the end of the cylinder to an intermediate position by two bias members respectively on axially opposite sides of the piston. Limit means associated with each respective bias member serve to coact between the respective bias member and the cylinder to limit the inward travel of the respective bias member in the cylinder to establish a constant position at which the piston receives no net biasing force from the two bias members. Each limit means may comprise a flanged cup which moves with the inner end of the bias member and a stop surface in the cylinder for engaging the cup flange to limit its inward movement, and thus the inward movement of the bias member. In one application the actuator forms part of a surface traversing apparatus, with the cylinder being fixed to a base portion of the apparatus and the piston serving to selectively position anchor fingers connected thereto to each of three precise positions relative to the cylinder in response to fluid pressure on the piston.

Method and arrangement for renovating a boiler

In this connection renovating a boiler (1) is disclosed. The boiler (1) may be a recovery boiler or a fluidized bed boiler, for example. The boiler (1) comprises a furnace (2), walls (3), a roof (4), and a water and steam system. The roof (4) comprises tubes that are a part of the water and steam system of the boiler (1). For the renovation new roof panels (7) with support brackets (8) at their ends are provided. Old roof panels are removed, and the new roof panels (7) are positioned in place. The new roof panels (7) are supported by the support brackets (8). The new roof panels (7) are used as scaffoldings during the renovation. The tubes (7a) of the new roof panels (7) are connected to the water and steam system of the boiler (1) to form a part of the water and steam system of the boiler (1).
