ASTM A240 F304/1.4301 Stainless Steel Baffle Plate For Heat Exchanger Application
A240 304 Stainless Application scope
System description: A240 304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending.
Corrosion resistant in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion.
It is suitable for food processing, storage and transportation.
Has good processing properties and weldability.
Plate heat exchangers, bellows, household products (category 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, Agriculture, ship parts, etc.
304 stainless steel is a nationally recognized food grade stainless steel.

What is Baffle Plate?
The baffle plate also referred to a heat deflector plate, sits at the top of the fire box chamber. Baffles can be made of cast iron, heavy steel, stainless steel or vermiculite. It is designed to deflect heat back into the fire box to prevent waste gases and heat being lost through the flue too quickly. By reflecting heat back into the firebox this aids in secondary combustion of waste gases to produce even more heat.
Use of Baffle:
The main roles of a baffle in a shell and tube heat exchanger are to:
Hold tubes in position (preventing sagging), both in production and operation
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
In a static mixer, baffles are used to minimize the tangential component of velocity which causes vortex formation, and thus promotes mixing.
In a chemical reactor, baffles are often attached to the interior walls to promote mixing and thus increase heat transfer and possibly chemical reaction rates.
In a household stoves like Handölkassetten and similar stoves a baffle is used to prevent the gas from going directly up in the chimney and possibly causing a chimney fire and direct the gas towards the front of the oven before it continues upwards into the chimney. In this case the baffle helps increase the efficiency of the stove as more heat leaves the gas before it exits.
The baffles prevent the rotational flow without affecting radial or longitudinal flow. The tank is provided with baffles which prevent swirling and vortex formation. Except in very large tanks, four baffles are placed.
