Boiler Stainless Steel Exhaust Flue Stack. This change of state of flue gases in the vent pipe depends on many different variables like length of run, the efficiency of the boiler or furnace, type of material used in the flue, the temperature of the flue, and ambient temperature outside and where the flue pipe is running.
Gas Oil Vent Flue Vents Materials Table - Gas and oil vent flue piping uses different types of materials depending on the applications. It is important that gas or oil flue vent pipes are installed correctly and maintained throughout the life of the furnace This pipe has a condensation problem which an adept technician will recognize and take corrective action before the corrosive effects of
Feb 09, 2005· We are looking at replacing the top section of a 75foot boiler stack. The stack is a self supporting stack and has a 3.5ft inner diameter at the last 50ft. This section was just replaced 12 years ago. It was 7/16" thick A285 Gr C carbon steel. It is eaten away by the flue gas from the boiler.
Factory built for boiler breeching, engine exhaust, and chimney stack. Grease duct (DIS only) and diesel exhaust applications. Thick-gauge material for the inner pipe and coupling provides a strong and rigid assembly. Self-centering flue design significantly simplifies and accelerates the installation process.
The service conditions of a fossil fueled boiler are among the most severe of any large engineered structure. Flame temperatures may reach more than 30000F. Flue gas and ash contain many species that are corrosive to the materials of construction. The steam side environment for superheaters and reheaters is generally nearly
Exhaust gases go up a flue and steam or hot water enter the piping system. In steam systems the vapor condenses as it cools and the condensate returns to the boiler to be reused. Condensing boilers tend to produce a corrosive condensate, (actually carbonic acid,) in the exhaust stack. Boiler Maintenance
You might want to look at Corten steel, as an option. This is a steel designed for outdoor use, a weathering grade of steel. I would not use A 36 fI don't think Corten would help against the flue gas corrosion but the nickel base alloy liner sleeve is a good suggestion. I have never found anyCarburize; We had two metal stacks collapse in the 1950's (well before my time) at two (one is now retired) of our power stations in the Midwest. WReally - if you have any kind of literature reference I would be very interested to add these to my database.Note that A36 or A516-70 would normally be used for availability or strength or ductility reasons, and aren't normally considered any more corrosioCarburize; I have at least one copy of one of the actual reports, which I can retrieve. I am going on memory here but the steel used at that time wCorten is the best material. The only problem is that it will bleed and discolor any concrete foundations. Hi temp. paint will help to control theJust some thoughts of the top of my head. What is the sulphur content of your fuel? Can this be reduced. We ran for many years on <3.5% content witJaypack. I think before choosing material you should know the exhausht gas temperature and content of exhaust gas.Then you can choose materials.Ifmetenrg - I have e-mailed the forum web-masters to see if there is any way they can provide an upload area where reference articles, images etc cou The medium pressure boiler pipeline mainly adopts hot rolling process or cold drawing process. b. High pressure boiler pipes are often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and steam, the pipe will occur oxidation and corrosion.
Can a brass fitting be used to connect a condensing boiler flue condensate or will this corrode? This question and answer were posted originally at CHIMNEY WET TIME & CORROSION. Reply: use corrosion-resistant piping for condensate disposal. Condensate from condensing boilers is quite corrosive, a view shared by experts (Xinqiao 2006).
The Accel CS Boiler can generate exiting flue gas temperatures between room temperature and 230oF, depending on the modulated firing rate and the boiler water temperature. The Accel CS boiler can be safely vented using a variety of venting materials. Approved materials include stainless steel, such as 316, 316L, 316Ti or AL 29-4C.
