HRST, Inc. provides power plant boiler technical service and products.  We specialize in Heat Recovery Steam Generators (HRSGs) and Waste Heat Boilers. Our engineers, technicians, and designers pride themselves on performing quality inspections, detailed analysis projects, developing engineered design upgrades, serving as Technical Advisors to plants, and offering professional HRSG training courses to help our clients avoid and solve boiler problems.

Since 1998, HRST has specialized in technical services and product designs for heat recovery steam generators (HRSGs), waste heat boilers, and smaller gas/oil-fired power boilers globally. 

HRST, Inc. was founded in 1998 by Robert Krowech.  Krowech started the business as a one-man operation in Minnesota, USA, with the goal of providing superior boiler engineering and on-site power plant technical service. His 22 years of previous boiler engineering and management experience for a boiler manufacturing company serves as the foundation HRST, Inc. has built upon.

As our business has continued to grow, we have increased our service and product capabilities. Our clients not only rely on us to help them find problems and determine the root cause but also to supply the solution in the form of engineering and fabricated components. We have developed a three-step cycle: Inspect. Analyze. Solve.® If our engineers and technicians inspect a boiler and find problems, they can immediately communicate with our design team, and utilize the field data, pictures and history to analyze the problem, and then provide a solution. This allows our clients to focus on other tasks within the power plant. More importantly, our customers have confidence that the HRST, Inc. fix will solve the problem the first time.

Our understanding of boiler problems, combined with investment in research and development, has resulted in innovative products to help our clients. These products include pipe penetration seals, economizers that resist thermal shock, finned tube gas side cleaning techniques and innovative components to improve boiler lay-up.

In addition to our Minnesota Headquarters, we have five regional offices located across the United States, as well as representation in Australia and Vietnam.
