according to my view the chimney is same as that of stack the only thing is height.in chimey less amount of co2,co,sulphur di oxide etc comes out which means less ppm ( parts per million ) they do not affect the living beings.in stack more amount of co2,co, sulphur di oxide evolves and they affect the living being .so, it should vent out at some distance from the ground level.

ReneA chimney is a structure that is typically used to vent smoke from a fireplace or stove in a residential setting, while a stack is a similar structure used in industrial settings to vent various types of gas emissions from factories or processing plants. Chimneys are usually smaller and made of brick or metal, while stacks are larger and made of steel or concrete to withstand higher temperatures and harsher conditions.

What is the difference between flue gas and stack gas?
Flue gas is the gas that is emitted from a combustion process within a building or industrial facility, while stack gas refers to the mixture of gases emitted from a chimney or stack. In general, flue gas is the specific type of gas that is produced from a specific process, while stack gas is the broader term that encompasses all gases emitted from a stack or chimney.
How does a chimney work using convenction?
A chimney works by creating a temperature difference between the air inside and outside the chimney. When the fire heats the air inside the chimney, it becomes less dense and rises, pulling in fresh air to feed the fire. This convection process helps draw smoke and gases up and out of the chimney.
Difference between combustible and noncombustible fireplace?
A combustible fireplace is designed to burn actual wood or other combustible materials, requiring a chimney for ventilation. A noncombustible fireplace uses electricity or gas for heating, eliminating the need for a chimney.
What is called dirt from the chimney?
The buildup of soot and creosote from the chimney is often referred to as chimney residue or chimney deposits. This residue can be a fire hazard and should be regularly cleaned to maintain a safe and efficient chimney.
Why does smoke from a fireplace go up the chimney instead of out into the living room?
Smoke rises because it is hotter and less dense than the air around it. The chimney is designed to create a draft that pulls the smoke up and out of the fireplace, preventing it from flowing back into the room. This draft is created by the temperature difference between the inside and outside of the chimney.
