Boiler feedwater is treated to prevent issues such as scale, sludge, and corrosion. Different processes can be used, including deaeration and filtering. Untreated feedwater can reduce efficiency and damage components. Corrosion is caused by carbon dioxide and oxygen, which can be removed with a deaerator or chemical scrubbers. Alkalinity levels must also be adjusted to […]
Feedwater heaters gradually heat water for steam boilers to prevent thermal shock. They increase efficiency by using alternative heat sources and are regulated to optimize steam extraction. Closed feedwater heaters are preferred to prevent corrosion and contamination. Alternative methods include economizers and excess heat from steam engines. A feedwater heater is a device used to […]
Feedwater heaters preheat water in steam turbine and locomotive boilers to improve efficiency and prevent thermal shock damage. There are two types: open and enclosed. Open heaters mix steam directly with water, removing corrosion-causing oxygen. Enclosed heaters heat water indirectly through a bundle of pipes in a sealed shell. A feedwater heater is a component […]
