The following losses are applicable to liquid, gas and solid fired boiler L1Œ Loss due to dry flue gas (sensible heat) L2Œ Loss due to hydrogen in fuel (H 2) L3Œ Loss due to moisture in fuel (H 2 O) L4Œ Loss due to moisture in air (H 2O) L5Œ Loss due to carbon monoxide (CO) L6Œ Loss due to surface radiation, convection and other unaccounted*.
Boiler Post Purge When a boiler is turned off some heat remains in the mass of the boiler. If the flow through the boiler is stopped at the same time the boiler is shut off, the residual heat is lost. Therefore, after operation of the boiler the residual heat in the boiler should be purged to the system in order to decrease standby losses.
Mar 20, 2016· Before I get into the purge cycle losses, it is worth pointing out that the flue gas temperature profile provided another clue into a potential optimization opportunity. Specifically, the flue gas temperature is an indication of the efficiency of the combustion process.
Wet flue gas loss Wet products of combustion are obtained from the following components in fuel : Moisture Hydrogen – Burns to form water vapour 18 1 Kg of hydrogen burn to form 9 Kg of moisture The heat lost with the mass of the water vapour along with flue gas to the atmosphere is known as wet flue gas loss
Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

Aug 27, 2018· The major energy losses associated with boilers fall into two categories: stack losses‚ and radiation and convection losses. Stack Losses. Stack losses represent the heat in the flue gas that is lost to the atmosphere upon entering the stack. Stack losses depend on fuel composition‚ firing conditions and flue gas temperature.
Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.
Calculation of Wet Losses in stack: Eq-11 Boiler Efficiency: Eq-12 Assumptions The assumptions used in this calculation are the following: 1. One percent energy loss from radiation and surface convection. 2. Loss associated with carbon monoxide in flue gas is negligible. 3. Loss associated with moisture in fuel …
Apr 18, 2017· As flue gas temperature increases, so do flue-gas heat losses. Flue gas heat recovery is possible with the installation of specialized equipment. However, too much heat removal may lead to more water condensation and increased corrosion. Use of certain metals can protect against this. Miscellaneous Heat Losses – Miscellaneous heat losses can also be an issue for cyclic boiler operations. Pre-purge and post-purge losses…
Jul 17, 2017· Purging a boiler is a simple way of saying that you are going to get the air out of it so the water can run freely. Air bubbles stop water flow and need to be purged, or the boiler will not function. If you are having trouble getting sufficient hot water, then your hot water boiler may need purging.
