WebMay 6, 2024 · Water in the system is bad for your boiler because it can lead to water hammer and other issues. If foaming occurs in your boiler, check the pH level – it should be between 7 and 9. But a high pH level is not the only thing that causes foaming. When your boiler water violently bounces, this is called priming.

WebAs the water boils its density decreases and there is circulation of hot water and steam. Steam is separated from water in steam drum and taken out. Longitudinal drum boilers range from 2250 kg/h to 3600 kg/h. 2. Cross drum boiler : The drum in this type is placed in cross to the heat source. WebJan 28, 2024 · However, the piping pitch is much more crucial to this system. The piping must have pitch or fall to help the steam rise, and more importantly, to allow the condensate to flow back to the boiler. Level piping holds water, so it must have fallen. Also, a Hartford Loop is required to connect the supply and return.

WebFormation of scales may be due to; (1) Decomposition of calcium bicarbonate. Ca (HCO3)2 → CaCO3 ↓ + H2O + CO2 ↑. Scale. However, scale composed chiefly of calcium carbonate is soft and is the main cause of scale formation in low-pressure boilers. But in high-pressure boilers, CaCO3 is soluble. CaCO3 + H2O → Ca (OH2)2 (soluble) + CO2 ↑.
