2020-5-6 · Warning: Chemical Cleaning May Be Hazardous To You And Your Boiler. The chemical cleaning of a boiler is a project fraught with danger and horror stories abound. For example, a few years ago a power boiler was cleaned with ammoniated EDTA (ethylenediaminetetraacetic acid).

The boiler water side (interior) must be carefully inspected at least twice a year. Yearly. Check of the water side of the boiler and hotwell/deaerator for corrosion and scaling. Check the chemical pump unit. Reference: AQ-2 Boiler Manual by Aalborg Industries

Waste heat boilers are used in many industries. In steel mills, two furnaces supply heat to one boiler. Energy sources are recovered from diesel engine exhaust, ore refineries, and cement kilns. These boilers are also common in the paper and wood industries. The boiler shown below is a tail gas fired waste heat boiler.

Keeping dissolved solids below the concentration that causes foaming requires continuous or periodic blowdown of the boiler. High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter. Where a chemical species is sufficiently volatile, it also carries over as a vapor in the steam.

In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner. The boiler should also be designed to generate high quality steam for plant use. A flow diagram for a typical boiler plant is presented in Figure 12.l.

: 99KBThe energy can be released or absorbed. For example, combustion releases more energy than is needed to initiate the reaction. Photosynthesis absorbs more energy than it releases. Examples of Chemical Energy. Basically, any compound contains chemical energy that can be released when its chemical bonds are broken. Any substance that can be used

As an example, corrosion during operation of the boiler is often caused by concentration of sodium hydroxide, concentration of caustic-forming salts such as sodium carbonate, or concentration of acid-forming salts such as magnesium chloride or sulfate.
