Boilers - Visual Encyclopedia of Chemical Engineering

Waste heat boilers recycle the heat, steam, or combustible by-products of other processes to provide energy. Equipment Design Because of their unconventional fuel source, waste heat boilers have a unique design. Waste heat boilers generally have larger intake capacities than other types of boilers because the entering fuel is not very efficient.

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.

Waste Heat Boiler - an overview | ScienceDirect Topics

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.
