Beijing's burning issue – reducing boiler NOx emissions

A chimney is a structure that provides ventilation for hot smoke or smoke from a boiler, stove, furnace or fireplace. A chimney is usually vertical, or as close to vertical as possible, to ensure that gases flow smoothly, drawing in air into what is known as a chimney burn or chimney effect

Chimney Area. The velocity of air and flue gas in a smaller furnace should not exceed 2 m/s. Design velocities of larger furnaces should not exceed 10 m/s. Required chimney area can be calculated as. A = Q / v (3) where. A = cross-sectional area of chimney (m 2) Q = volume of flue gases at chimney temperature (m 3 /s) v = velocity (m/s)

Protecting Boilers Against Flue Gas Condensation | 2017-08

Before thinking about sharing a chimney flue - generally prohibited as a safety concern but permitted in some jurisdictions, particularly with gas and oil fuels provided proper venting arrangement - I'd check with your local building department about what they permit. Permission may also depend on the chimney type and design.


The firebox, or combustion chamber, of some boilers is also called a furnace. Boiler design provides for connections to a piping system, which delivers heated fluid to the point of use and returns the cooled fluid to the boiler, and also to a combustion air source and flue gas chimney.

Flue-gas stack - Wikipedia

May 25, 2005 · Because burning one pound of fuel oil in air also produces 1.18 pounds of water (as steam vapor), unless the boiler can condense and recover the latent energy in the steam, it also just goes up the stack, and is the main reason for chimney condensation problems (gas produces even more water per pound of fuel).

Chimney for gas boiler: installation and requirements

The design of a chimney for a gas boiler is designed on the basis of the current norms and parameters of the heating equipment. It is desirable that the gas boiler is installed in a separate boiler room with ventilation, on the ground floor, to ensure the escape of carbon monoxide. The entire heating …

Precautions in chimney design: (i) gas velocity through the stack should fall in suitable range to ensure good effluent dispersal and avoid flow noise under all operating conditions. (ii) gas temperature should be maintained near to the entry level by effective insulation; this is to prevent corrosion problem created by acidic moisture condensation.

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a 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
