The document introduces HRSG SOLUTION, an integrated software for designing heat recovery steam generator (HRSG) boilers. Some key features of the software include: carrying out basic design calculations and performance analysis; estimating boiler weight and price; releasing final design documents; and being extensible. The software allows inputting gas turbine and burner information, setting heat exchanger parameters, and performing circulation analysis, pump calculations, and insulation thickness calculations to facilitate HRSG design.
