Combustion and heat transfer in large boiler furnaces

Radiant Heat Transfer In the furnace chambers of water-tube boilers the heat transfer process is almost wholly radiant, with less than 5% of the heat transferred by convection.22 Unlike the radiation emitted from a solid the radiation from a flame emanates from within the volume of the flame.

Boiler Fundamentals and Best Practices

Steam Production. From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2, kpa.

Measurements of Local Heat Flux and Water-Side Heat Transfer

steam boilers failed due to calculation of inside heat transfer coefficients. The heat flux can only be determined accurately if the inside heat transfer coefficient is measured experimentally. New numerical methods for determining the heat flux in boiler furnaces, based on experimentally acquired interior flux-tube temperatures, will be presented.

Boiler Heat Exchanger: Aluminum vs Cast Iron vs Stainless Steel

Cons: Aluminum doesnt transfer heat as well as stainless steel, and it cannot be used in condensing boilers. The bottom line: Aluminum heat exchangers are found in boilers in the 90% to 94% efficiency range like the Utica UB90-100 IV 90% boiler and the Weil McLain Ultra Gas S3 CT with models from 92-94% efficient.
