Use of baffles
Prevent the effects of steam starvation, which is increased with both fluid velocity and the length of the exchanger. Direct shell-side fluid flow along tube field. This increases fluid velocity and the effective heat transfer co-efficient of the exchanger.
What is the function of a baffle?
Baffles serve two important functions. First, they support the tubes during assembly and operation and help prevent vibration from flow-induced eddies. Second, they direct the shell-side fluid back and forth across the tube bundle to provide effective velocity and heat transfer rates.
When should I replace my baffle plate?
When a baffle warps, it can disrupt how efficiently and effectively a stove is operating, and so will need to be replaced for the stove to return to fully working order. As long as the stove has been properly operated and maintained, baffle plates can last for long periods of time.
Do you need a baffle in a wood stove?

What are baffles in exhaust?
Exhaust baffles are metallic chamber parts that are acoustically tuned and fit onto the exhaust pipe’s muffler. They function to cancel out or muffle the loud noise created from the exhaust pipe. Most motorcycles come with a standard baffle or muffler required by law to reduce the engine’s natural noise levels.
How many types of baffles are there?
There are two main types of baffle which give longitudinal flow: Orifice Baffle, Rod Baffle.
How long do baffle plates last?
They are positioned in perhaps the hottest part of the stove with the aim of keeping burning and unburnt gases in the firebox for as long as possible. Nonetheless, some people can make a wood-burning stove baffle last for several years, while others find they have burned through or warped the baffle within a year.
Why does my wood burner smoke when I open the door?
Your wood stove relies on suction, called draft or draught, from the chimney to draw the smoke up out of your wood stove and out of your house. There are a few items that can cause bad draft in wood burning stoves: a cold chimney, wind induced down draft, or even a clogged or obstructed chimney.
Where should the baffle plate sit?
As the descriptive queries we receive suggest, the baffle plate sits at the top of the inside of a woodburner, just below the top of the firebox. Its purpose is to stop gases escaping straight up the flue pipe. The baffle serves as a barrier to the most direct route for gases to leave the firebox.
How do I know if my wood stove is leaking?
If your wood stove isn’t airtight, you’ll see smoke entering your stove where the leak is located.
What is a sump in a car?
The oil sump contains the engine oil required for lubrication. The oil is extracted from it by an oil pump and conveyed into the engine block’s oil ducts via the oil filter. The oil then flows back into the oil sump from the lubrication points.
What are valve cover baffles?
There is usually a baffle inside the valve cover to help control the oil and keep it from spraying out, but these baffles may not clear some valve trains, particularly when you’re using wide-bodied aluminum rocker arms.
