Heat recovery steam generators for small scale power generation from 2.5 to 60 МW
Heat recovery steam generators (HRSG), steam type and water heated type with horizontal hot-water heat-recovery boilers with horizontal and vertical gas flow, natural circulation, equipped with duct burner or without it. Hot‐water heat‐recovery boilers with horizontal and vertical gas flow.
- Horizontal configuration of the heat recovery steam generator with natural circulation with stack fitted closely to the boiler has compact dimensions, comparable with those of the vertical configuration boilers, however the horizontal boilers are more economical, reliable and simple in service;
- Special design solutions aimed at improving compactness of the boiler and its components (installation of the blocks without impellers closely to each other width-wise, direct steam discharge pipes, lack of warm box, etc. ;
- High modularity of the boiler design;
- Simplicity and high speed of installation;
- Low weight modular design of the boiler frame;
- Free expansion of heating surface tubes downwards;
- High multiplicity and uniformity of circulation;
- Lack of unreliable and costly circulation pumps;
- Reduced demand for electric power by eliminating circulation and recirculation pumps;
- Lower consumption of spare parts and reduced volume of maintenance;
- Low pressure evaporator from alloy steels reduces corrosion multiple times;
- Lack of heated external downcomers;
- Automatic heating surface drainage system;
Special design of economizer provides a complete uniformity in the fields of velocity and temperature of mediums in the bank as well as eliminates the problem of medium boiling in tubes.
