<p>The steam generator sheet-metal economiser casing suspension arrangement is partic. for grate-fired plant. There are gastight welded tube walls enclosing the first pass and the upper part of the - pref. evaporative - second, and the rear wall of the former constituting the front wall of the latter. A first, rear, load-carrying casing panel (9) hangs from the second-pass (3) rear tube wall (10). A second, front panel (12) hangs via adjustable links (11) from evaporator-section tubes (13) linking the rear wall drain header (14) to the outlet header (15) in the gastight roof (16), through gaps (17) in the second-pass additional evaporative heating surface (18).</p> |
