FIELD: civil engineering. SUBSTANCE: gas-turbine block has load-bearing framework with roofing trusses and crane-carrying girders, bridge crane, heat-recovering boiler with gas outlet duct located above it. Bridge crane is mounted on removable crane-carrying girders in zone of gas outlet duct location. Roofing trusses are installed on load-bearing framework for creation of space between trusses and gas outcome duct to allow positioning of cantilever crane within overhead limits of bridge crane. Method of mounting implies installation of units of heat recovery boiler and auxiliary equipment by bridge crane and mounting of gas outcome duct by means of overhead crane. After mounting of above machinery and equipment, bridge crane and crane- carrying girders are dismantled. Then, overhead crane is attached to overhead transportation tracks secured to roofing trusses within top limits of bridge crane so as to install gas outcome duct and remaining auxiliary equipment. After mounting of gas-turbine block equipment, overhead crane is used for repair operations. EFFECT: high efficiency. 2 cl, 3 dwg |
