Reasons for Increasing Exhaust Gas - EPCB Boiler

Aug 01, 2007 · Apparently, the pressure fluctuations in the waste gas distorted the fuel gas/air mixing process at the existing frequency, and the energy already available from the flammable mixture pockets was redirected from standard combustion noise to the new frequency, which happened to be the same as the resonant frequency of the furnace system.

Finding the Root Cause of Boiler Tube Failures

Flow induced vibration in tube bundles subjected to cross flow has been known for a long time. In boilers, tube bundles carrying steam or water are subjected to cross flow of flue gases. This flow causes external forces which may generate vibrations

Vibration Issues in Boilers & Furnaces

Apr 24, 2020 · The issue is so complex for several reasons: Vibration can be caused by a single component of the system or the interaction of multiple components. Where vibrations manifest in the system may be far away from the source. "Identical" units do not exhibit the same behavior (i.e. one may vibrate and the other does not).

Combustion Pulsation and Noise - Process Heating

Sep 03, 2019 · It starts the noise when dhw is flowing through at half flow (tap only opened a little) and when the water temperature of the boiler is set low. Changing the water temperature output to high or opening the tap to max stops the vibration. It recently started vibrating also in central heating mode. Here vibration occurs at 55-60 degrees.

BOILER INSTALLATION GUIDE - MemberClicks

Stresses may be associated with vibration due to flue gas flow or sootblowers (high-frequency, low-amplitude stresses), or with boiler cycling (low-frequency, high-amplitude stress mechanism). Components typically affected: Fatigue failures will most often occur at areas of constraint such as tube penetrations, welds, or supports.
