HEAT RECOVERY BOILERS

Boilers designed to recover heat from high temperature gases exhausted from glass making plant have to offer very low pressure drop to the gas stream and the tubes have to be arranged such that deposits, which are unavoidable as a result of the excess of sulfur trioxide in the gas, can be treated and removed regularly by soot-blowing.

Factors Affecting Claus Waste Heat Boiler Design and Operation

recent industry survey of Waste Heat Boiler design and operation in existing SRUs was performed to explore the determining factors in good WHB design and operation practices (reference 4). This survey has indicated that neither mass flux nor tube diameter is an indicator of risk of failure. The survey confirms that the failure mechanisms can be attributed to a combination of factors which may be design …

Waste heat recovery boilers (WHRB) | Danstoker

A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
