Hennigan Engineering Co., Inc. has been providing comprehensive boiler system cleaning services to a variety of customers throughout the years. From Superheater descaling to Feedwater Heater tube hydrolasing, our cleaning systems are designed to restore maximum performance.
The use of high pressure water jetting tools has become standard practice for thorough furnace cleaning. Manual and remotely operated hydrolasing accessories are utilized at pressures of 8,000 -20,000 psi for the removal of scale, slag and ash from Superheaters, Water Walls, Economizers, and Air Preheaters.
Many municipalities and major utilities have discovered that high pressure water jetting is both the quickest and most economical way to restore efficient operation of their boiler systems. From 500 horsepower package boilers to 1,000+ megawatt coal fired units, hydrolasing provides superior cleaning results.
Where applicable, water tube internals can be effectively cleaned free of chemical and scale deposit build-up in a manner similar to that used in our heat exchanger cleaning process. For safety and insurance inspections, the use of 30,000 – 40,000 psi rotary water jetting guns are used to clean water wall welds and ligaments to white metal for UT testing (without using abrasive blast media).
The expense of the cleaning process is rapidly recovered in increased power output and significant fuel savings.
