Ensuring overall system reliability for the Chemical & Refinery Industry.
Combined General understands the extreme conditions of Chemical & Refinery boiler systems and how they can impact plant operations.

Chemical & Refinery Boiler Types
Chemical & Refinery boiler types are subjected to constantly changing conditions and are at high risk for boiler corrosion, tube scale, fouling, and/or failure of critical equipment such as economizers and turbines. Our chemical cleaning process can remove residual deposits of rust and mill-scale that can hinder flow and circulation.
All Refinery & Chemical boiler servicing projects include an extensive constructability and preplanning phase to identify opportunities for cost and labor reductions. Our extensive planning has been proven to improve overall efficiency and ensure long-term, reliable boiler performance.
