Calculating Boiler Chemical Requirements Water
2017-6-26·CHEMICAL EQUIVALENTS A. Equivalents and equivalent weights The concept of equivalent weights, equivalents, and equivalents per million (epm) is most useful in calculating basic chemical dosages. The equivalent weight of any ion, radical or compound is that weight which will combine with or replace a unit weight of hydrogen. All ions (and compounds) react together

Calculating Boiler Efficiency - Forbes Marshall
H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable

An integrated method using MACBETH and EDAS
According to the results of the integrated method final ranking of steam boiler alternatives is obtained as A 1 > A 4 > A 3 > A 5 > A 2. As a result, the most appropriate steam boiler for the dyehouse is found as A 1 alternative. So it is advised to the dyehouse of the textile company to select the A 1 steam boiler.

Steam Pressure Reduction: Opportunities and Issues
2013-9-26·Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boilers net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
