Boiler feed water - Lenntech

The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).The make-up water is usually natural water either in its raw state, or treated by some process before use.

Boiler Mountings And Their Function - Complete List

Aug 05, 2018 · Boiler mountings are a set of safety device installed for the safe operation of a boiler. There are seven main mountings on a boiler shell; safety valve, steam stop valve, vent valve, pressure gauge, water level indicator, feed check valve and fusible plug.

If a boiler water possesses embrittling characteristics, steps must be taken to prevent attack of the boiler metal. Sodium nitrate is a standard treatment for inhibiting embrittlement in lower-pressure boiler systems. The inhibition of embrittlement requires a definite ratio of nitrate to the caustic alkalinity present in the boiler water.

Jun 12, 2017 · This boiler water control method was developed to insure that hydroxide formation does not occur under hideout conditions. Here the boiler water chemistry is controlled to achieve zero free caustic alkalinity. The sodium to phosphate ratio is maintained between 2.3:1 and 2.6:1 via the pH versus PO 4 control chart.

Characteristics of boiler feedwater - Lenntech

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

Sep 03, 2020 · When testing boiler water, it is important to understand what you are testing for. ALKALINITY. The presence of Alkalinity in a water sample may be due to many different substances. For the sake of simplicity, the presence of Bicarbonate, Carbonate and Hydroxide contributes to the alkalinity of water. P ALKALINITY.

Alkalinity, especially by boiler water chemists, can be reported as M-Alkalinity and P-Alkalinity. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of ppm as calcium carbonate. The M-Alkalinity measurement is based on a sulfuric acid titration using a Methyl orange
