    11 Losses due to heat transfer (radiation) to the environment The main form of heat transfer from boiler to boiler room is radiation. It is proportional to the outer surface area of the boiler and is usually 200-300 W/(m2K) for a well-insulated boiler having its outer surface temperature below 55 °C.

  • The theory behind heat transfer - Alfa Laval

    Heat transfer theory The natural laws of physics always allow the driving energy in a system to flow until equilibrium is reached. Heat leaves the warmer body or the hottest fluid, as long as there is a temperature difference, and will be transferred to the cold medium.

    Condensing boilers use waste heat from flue gases to pre-heat cold water entering the boiler. Flue gases are condensed into liquid form, thus recovering their latent heat of vaporization, which results in as much as 10%–12% increase in efficiency. Modeling these heat transfer phenomena is crucial to control this equipment. Despite the many approaches to the condensing boiler modeling, the
