<p>The present invention relates to a method of and an apparatus for supporting walls of a thermal power boiler, which generally comprises the actual furnace and means for treating flue gases and, where the boiler in question is a circulating fluidized bed boiler, also means for circulating bed material and for returning it to the furnace. The invention especially relates to supporting the walls (12) of such a boiler, wherein the furnace (10) is suspended to hang on a supporting plane of the upper portion of steel structures especially arranged for the purpose, and the walls (12), being formed of the vertical water tubes of the boiler, are supported horizontally at least by means of buckstays (22) positioned substantially perpendicular to the water tubes, and vertical pillars (24) located outside the buckstays (22), which pillars (24) are attached to the ground or the base of the boiler building. In accordance with the present invention, it is a characterizing feature of the method of and apparatus for supporting walls of a power boiler, that one or more rigid planes (30) surrounding the whole boiler are attached to the pillars (24), and at least two water tube walls (12) on the opposite sides of the boiler are supported to said pillars (24).</p> |
