The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blowdown required. The chloride test is unsuitable for feedwater with low incoming concentrations and the concentrations in the feedwater must be averaged over time for accuracy. High boiler solids will lead to foaming, priming Get Price

May 09, 2020 · For many years, a water boiler was the 'go-to' water heater for both professional and D.I.Y. campervan builds. But, since the introduction of L.P.G. heaters that can supply on-demand hot water at a fraction of the cost, a modern-day water boiler is now struggling to be a viable option. But we're not saying a water boiler has no uses.Get Price
The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.Get Price
