The Concept of Condensing Boilers

In a traditional boiler, the flue gases exit at a temperature of more than 120ºC/248ºF. In a condensing boiler, the flue gases exit at much cooler temperatures (i.e., between 50ºC/122ºF and 80ºC/176ºF). In order to condense the gases in the venting, the flue temperature must be lower than the dew point temperature…

What temperature should a condensing boiler be set at

A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature.

Coal Boiler vs Gas Boiler Running Costs - Diesel Boiler

Mar 04, 2020 · 1. Gas boiler running costs. The amount of natural gas required to produce 1 ton of steam from a gas boiler = heating capacity of the boiler ÷ calorific value of natural gas ÷ thermal efficiency = 600,000 Kcal ÷ 8600 Kcal / m³ ÷ 99.8% = 69.9 m³; combined with the natural gas market price of 3 yuan / m³, the gas boiler generates 1 ton The

Flue Gas Temperatures and PVC Venting - Cause for Concern

The high temperature of flue gases is a major concern to me due to the fact that Schedule 40 PVC pipe and fittings are only rated for 140 degrees Fahrenheit. I think we, in New England, are going to see PVC failures in the near future, directly related to the high flue gas temperatures of the new high-efficiency boilers.

Calculating Flue Gas Temperature - HVAC-Talk

Jan 09, 2020 · Flue gas temperatures on natural draft boilers (taken before the draft hood) should be 390ºf to 570ºf, if the unit is tuned properly by combustion analysis. This is based on water temperatures of 120ºf to 200ºf plus 270ºf to 370ºf. Instead of learning the tricks of the trade, learn the trade. Kefid20, 03:02 PM #10.

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived
