Flue-gas stack

A flue-gas stack is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device.

BOILER TYPES AND CLASSIFICATIONS

Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ''hot water boiler'' is used. Hotwater boilers that have temperatures above 250° Fahrenheit or pressures ...

Boiler Stainless Steel Exhaust Flue Stack

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.

Boiler Economizer Exhaust Heat Recovery Systems

Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids. Combustion ...

The following brief description of the steam locomotive boiler will acquaint inspectors with its construction and summarize the inspection procedure. For repair information and additional construction illustrations, the new NBIC Appendix H, Steam Locomotive Fire Tube Boiler Repair is recommended.

Boilers

The boiler shown above is a single furnace, two pass design. Larger boilers may have multiple furnaces and have multiple passes by replacing the exhaust stack with a return chamber and fitting another bank of tubes. The smoke tubes may be plain or threaded to act as stays. There are one stay tube for every three plain tubes approx.

Steam Boiler: March 2011

The corrosion can be prevented if the metal temperature in the steam boiler is maintained in high temperature. The flue gas temperature exit of steam boiler is usually maintained at minimum 200 o C to avoid the formation of acid in air heater, economizer, stack and other pressure part also flue gas.
