Boilers, like all types of equipment, have fundamentally different-looking constructions depending on the boiler size, use, and fuel type. The main boiler usage classes are utility, industrial, heat recovery steam generators (HRSG), and process. Boilers are also

Industrial Hot Water Boilers are generally selected when the required process temperature is relatively low – typically less than 90°C. When higher temperatures are needed then alternative forms of heating such as high-pressure hot water, steam or efficient Thermal Fluid systems are used. However, the simplicity and generally low

Vacuum deaerators are used primarily on water streams to remove dissolved gases including oxygen, nitrogen, carbon dioxide and volatile organics that can produce corrosion, scaling and plugging of piping and injection systems. When used in boiler feedwater treatment systems, they provide a cost-effective means of removing carbon dioxide between

9/8/2019 · Deaerator working principle, Types and Process Control. Deaerators is commonly employed in any chemical process industry or in Power Plants wherever boiler is utilized for steam production from boiler feed water. Deaerator solves the aim of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before going in boilers.

Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.

Vacuum deaerators remove dissolved gasses from boiler feeds. Removing these gasses via vacuum is more economical than removing them through chemicals. The systems reduce corrosion in boiler tubes caused by dissolved oxygen and carbon dioxide. Deaeration is based on several principals. However, Henry's Law is the driving principle.

The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system
