    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.

  • failure analysis of waste heat boiler tubes


    A petrochemical plant was shut down due to tubes leaks in a waste heat boiler (WHB). The failed WHB has been in operation for about 20 years, without any previous failure. Following the incident, inspection activities revealed the following: • Leaks were observed at 7 tubes. • Localized damage was observed on 70% of the ferrules.

    What is a Waste Heat Boiler? (with picture)

    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.

    Waste Heat Recovery System - an overview | ScienceDirect

    The first step in planning to install a waste heat recovery system (WHRS) is to work out the net available waste heat that can be used to generate power. 2.1.1. In a cement plant, waste heat is available mainly from kiln exhaust gases and vent air from the clinker cooler. Waste heat is also available from the exhaust of diesel engines of DG Set.

    As posted yesterday about my process stream operating conditions for my waste heat boiler, there has been some changes. My inlet remains at 400degC and 2 atm (because this is the optimum operating conditions for my reaction) however my outlet is now at 68.65degC at 1.85 atm. I have learnt that boiler feed water is used generate steam.
