Marine Engineering: Boiler Water Testing

Dec 15, 2010 · Phosphate ppm Test (PO4) Purpose: 1.It helps to maintain a phosphate reserve in the boiler to counter any possible contamination of the boiler water by corrosive and scale forming salts. However, too much phosphate in the boiler may also contribute to foaming and priming. Procedures: 1.Take the comparator with the 10 ml cells provided.

Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
