Flue Pipe: What is it and What Are Its Uses

A boiler flue is a pipe that carries exhaust gases produced by a boiler outside the home and releases it into the atmosphere. Boilers burn fuels such as gas or oil to heat water, a process that creates harmful by-products such as carbon monoxide. The boiler flue expels these by-products outside the home for the safety of those living inside.

What is a Boiler Flue and How do they Work? | Heatable

The flue is simply a piece of pipework or duct that moves gases and hot air from the combustion chamber of the boiler to outside. With condensing boilers, the flue is effectively part of the heating system, as it is the heat from the burned gases that starts warming the returning water from the system. While the incoming water is getting warmer, the hot combustion gases are losing some of their heat …

Basics of hot water heating boilers - Specifying Engineer

Sep 18, 2020 · Flue side corrosion is caused by condensing of flue gases on the heat transfer surface or chimney. Condensation in the chimney can flow into the boiler to cause this corrosion. This condensation is highly acidic due to sulfur in the fuel and chlorides in the atmosphere.

What Is A Boiler Flue? | Vaillant

Nov 05, 2019 · Definition: A boiler flue is a component which enables gas to escape safely from boiler. In most cases, this is a pipe or a duct, which is fitted to the boiler to carry exhaust gases away from your home safely. The aim is to remove waste products without exposing you or anyone around you to them.

Optimizing Boiler-System Efficiency | HPAC Engineering

This causes an efficiency loss at lower loads due to the temperature drop across the throttle valves. In variable pressure operation, boiler pressure is varied to meet turbine requirements. This can significantly improve cycle efficiency when operating at low loads (15 to 40% of maximum continuous rating, or MCR). However, boiler response to turbine requirements is slower in this mode.

Boiler Flues - Ultimate Guide with Boiler Flue Regulations

Apr 26, 2021 · What is a boiler flue? By definition, a boiler flue is a duct or pipe for the expulsion of exhaust gases from a heating system or generator. In English – It's a pipe from your boiler to the outside of your house so the waste gases and condensation from your heating system aren't being pumped into your home – pretty important.

Boiler Operations That Affect Efficiency (Part 2)

Aug 26, 2011 · The flue gas losses on the other hand will be greater at greater loads as the exit gas temperature is greater at greater loads and decreases as the load decreases. The combination gives a somewhat flat or parabolic performance curve (Figure 3). The efficiency on a lower heating value (LHV) basis increases slightly from 91.44% at 25% load to about 60% load and then tapers off. To determine …
