Abstract:

Heat and material balances for sludge incineration can be divided into two (2) broad categories:

<list list-type="order"> <list-item>

Autogeneous - no auxiliary fuel required</list-item> <list-item>

Non-autogeneous - auxiliary fuel required to during steady state operation at desired temperature and XS air.</list-item> </list>

The method of solution for these two problems will be shown by way of the illustrative examples below.

As shown in the co-paper on Combustion Fundamentals, the enthalpy of flue gas is not a linear function. The literature contains several mathematical expressions that can be used to express this change over a given range of temperatures. For this Manual of Practice, straightforward fourth power polynomial equations to a 60°F base have been selected as the most functional. Unfortunately, neither these equations, nor the other enthalpy equations found in the literature, lend themselves to a direct solution when trying to calculate a temperature from an enthalpy value. The easiest and most common way to solve this problem is by using a trial and error solution. Before starting the first illustrative example, the Table of Molecular Weights from Combustion Fundamentals is repeated below for reference.
