  • Boiler Horsepower - Engineering ToolBox

    This chapter will first describe the radiation heat transfer between solid surfaces without considering the effect of the medium among them, that is, the medium is transparent. Transparent objects or media are those of which the transmissivity τ = 1. There are four kinds of situations introduced here.

  • Alfa Laval - Calculation method

    Calculation method. The heat load of a heat exchanger can be derived from the following two formulas: 1. Heat load, Theta and LMTD calculation. Where: P = heat load (btu/h) m = mass flow rate (lb/h) c p = specific heat (btu/lb °F) δt = temperature difference between inlet and outlet on one side (°F)

  • Scaling in boilers - Lenntech

    This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.
