  • De-scaling and De-sludging Of Plate Heat Exchangers

    As this facilitates heat transfer, the speed of warming increases. It is for this reason that plate heat exchangers are now becoming more common, with small brazed versions being used inside combination boilers and many larger buildings relying on them entirely for the supply of their hot water, using gaskets between the two plates.Learn More

  • What is a heat exchanger in a boiler? | Viessmann

    Viessmann boilers only contain one heat exchanger. The stainless steel design means that all of the heat generated can be extracted in one pass. This is due to the exchanger's larger surface area and the position of the burner, which sits centrally within the cylindrical heat exchanger.Learn More

  • Boilers - Primasonics International Ltd

    A boiler is a pressure vessel that is designed to generate heat, produce steam or cool gases. Typically built as a rectangular or cylindrical tube, the vessel is closed at both ends and is fully insulated. Fuels such as wood, coal, oil, or natural gas power the device, making it possible for pressures of 30 bar and more to be created inside.Learn More

  • Condensing theory - How do condensing boilers add

    Nov 16, 2018 · First of all you should understand the basic physics of combustion. CH4 +2O2 = CO2 + 2H2O + HEAT. (Note source of ignition is required) OR. Natural gas + 2 oxygens gives 1 carbon dioxide, two water molecules (typically water vapour) and heat. So in its purest form, the only by-products would be CO2, H20 and heat.Learn More

  • Furnaces and Boilers | Department of Energy

    Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere. AFUE doesn't include the heat losses of the duct Learn More
