Chevrons in a boiler refer to the angled or zigzag-shaped elements found within the heat exchanger or economizer sections. Their primary function is to enhance heat transfer efficiency by increasing the surface area and promoting better fluid distribution. This design helps to maximize the contact between the flue gas and the heat transfer surfaces, leading to improved thermal performance and energy efficiency. Additionally, chevrons can assist in reducing fouling by directing the flow of gases more effectively.

What is pf fired boiler?
For getting better efficiency from boiler, coal is pulverized in mills (powder form) before entering into boiler along with hot air. This is done in order to control damage to boiler tubes and plates due to high (but cheap) sulphur content in coal. These types of boiler are usually called super critical boiler and works on high pressure (3600psi) and temperature (610 degree C) unlike sub critical boilers. alok bh.

Are chevrons used in all military branches?
The short answer is yes and no. The Army and the Marine Corps have a very similar rank structure, with all enlisted ranks displaying chevrons, with the exception of Privates (E-1 in both services, no markings) and Specialist (E-4 in the Army, similar in look to a parachute). The Navy uses chevrons in enlisted ranks E-4 through E-6, however the chevrons are inverted with the point directed down. The Airforce uses chevrons in enlisted ranks E-7 through E-9. So yes the military uses chevrons in all branches, but some are inverted, and are not applied to all ranks.
