Heat Exchanger

Heat Exchanger

With a heat exchanger heat is transferred from a liquid or gas to another liquid or gas without requiring direct contact of the fluids. Within heat exchangers, heat is transferred from the warmer fluid to the colder fluid as both streams flow through the pipe network.

Boiler heat exchangers

In a boiler heat exchanger, heat is transferred from the hot gasses of a combustion process to water moving through the exchanger’s internal piping system. As a result, the water heats up as the gas cools down. Other appliances that utilize a heat exchanger include refrigerators and air conditioners, though the direction of heat transfer in these systems is reverse to that of a boiler.

Typical boiler problems

  • No heat or hot water – Broken diaphragms and airlocks, failure of motorized valves, issues with the thermostat or low water levels can result in no heat or hot water. Check if your boiler is not working on account of the boiler pressure or your thermostat. A broken diaphragm, airlock or valve may need to be replaced with a new part.
  • Leaking and dripping – The most common cause of leaking in a heat exchanger is a broken internal component, such as a pump seal or pressure valve. If the leak is emanating from the pressure valve, it may be that your boiler pressure is too high. If it’s coming from the pump seal, it may have become worn and needs replacing. If the boiler is leaking around the pipes or tank – it could be a result of corrosion or in some cases where the system has not been fitted correctly.
2017 is Liquid Process Systems’ 25th Year of Service to industries needing to filter hot oil / heat transfer fluid / thermal fluid / thermic fluid used in process heating and cooling – continuous filtration while plant and process operate. Industries served include manufactured/engineered wood, asphalt, die-casting, plastics, PET, adhesives, paints, chemicals, pharmaceuticals, supplements, medical devices, carpet, fiber, automotive, food processing, resort and institutional laundries, recycling, reprocessing, petrochemical and aerospace.
