Frank Lill & Son's highly skilled engineers utilize the latest computer systems to provide efficient and accurate designs. Heat Recovery Steam Generators are designed to match the requirements of a variety of combustion turbine generator designs. The HRSG provides the utmost in flexibility and performance while achieving increased environmental emissions control requirements. Frank Lill & Son offers the complete capability to install, modify and repair HRSGs. Heat Recovery Steam Generators optimize maximum utilization of shop-assembled or on site assembly methods. Truck and rail shippable modular designs allow for shorter time constraints. The results are simplified installation, improved flexibility and shorter construction schedules, which translates into minimum overall plant and project costs. Frank Lill & Son has experience with large shop-assembled and on site assembly of modular construction for utility and cogeneration combined cycle projects, including reheat for a number of combustion turbine types and sizes. Our extensive experience in the erection and operation of heat recovery steam generators puts Frank Lill & Son in the forefront of overall heat recovery technology development.
