The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Deaerators in Industrial Steam Systems - Energy
Steam, produced in the boiler at 10 bar g, is to be used as the heating agent. If the 'From and At' rating of the boiler plant is 10 tonne/h, determine the flowrate of steam required to heat the deaerator. Before any calculations can be made to estimate the size of the deaerator, it is important to know the maximum likely feedwater requirement.
Air acts as an oxidizing agent and causes corrosion and weakening leading to damage and leakage in pipes and related equipment. In Boilers it can cause serious accidents. Air gets in the system mainly through Boiler Feed water. The harmful element in Air is Oxygen, and De Aeration essentially involves removal of Oxygen. This is done by heating the water in the De-aerator Head (DAH) to 90Deg C when …

Pressurised Deaerator Head Description Spirax Sarco Deaerator Heads are designed for boiler feedwater treatment applications. They are recommended in order to reduce the cost or the impact of chemical treatment agents and to reduce the amount of dissolved oxygen and carbon dioxide. Oxygen and carbon dioxide are the main causes of corrosion in
Hurst Boiler & Welding Company, Inc. has been manufacturing, designing, engineering, and servicing gas, oil, biomass, and hybrid firetube and watertube steam and hot water boilers since 1967, for thousands of satisfied customers. In addition to a complete line of steam and hot water boilers, Hurst Boiler & Welding Company also manufactures a complete line of boiler parts and boiler room
In a steam deaerator, steam serves as the scrubbing agent to reduce the partial pressures of the gases being removed. The phenomenon of gas removal from water through the use of scrubbing in a deaerator can be accomplished in several different ways. With the scrubbing action occurring, the deaerator must vent the non-condensable gases
Since the deaerator is designed for degassing of the work-agent, it is used in combination with steel heating equipment. Most often deaerators are used in heating and hot water supply systems. Boiler-houses with water-heating boilers are usually equipped with the vacuum type units.
HP boilers can afford to go for a pressurized de-aeration system, But for process boilers a separate DA vessel will cost as much as the boiler cost and may not be affordable and justified. UDH UKL Deaerator Head for boiler feedwater tank in stainless steel and carbon …
A thermal deaerator is used for reducing the oxygen content of steam boiler feedwater. Without proper treatment, feedwater for steam boilers typically has a high oxygen content of 8-10 mg/l, which causes critical corrosion in the system. Theory of operation. The condensate and the make-up water are mixed so that a temperature of 60-70°C is
Pressurised Deaerators | Spirax Sarco
Deaerators provide the water storage capacity and the net positive suction head necessary at the boiler feed pump inlet. Returned condensate is mixed with makeup water within the deaerator. Operating temperatures range from 215° to more than 350°F, which reduces the thermal shock on downstream preheating equipment and the boiler. Insulation
