Condensing boiler and non-condensing boiler are two main types of gas-fired boilers on the market at present. A correct understanding of the difference between condensing boiler and non-condensing boiler can help you choose a reasonable type. Before introducing the difference between them, it is necessary to introduce the principles of condensing boiler and non-condensing boiler.
Introduction of working principle of non-condensing boiler
Non-condensing boiler is a kind of heat energy c...
Low-carbon condensing gas boiler takes clean energy natural gas as fuel, and uses high-efficiency flue gas condensation waste heat recovery device to absorb sensible heat and latent heat released by steam condensation in the tail of the boiler, so as to achieve the purpose of improving boiler thermal efficiency and saving energy, thereby reducing carbon emissions.
Low-carbon gas-fired boiler recovers the energy from the hot flue gas (generally around 140℃) emitted by the boiler through ...
Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
The principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
Fully premixed low nitrogen condensing boiler refers to a boiler using fully premixed combustion technology. Fully premixed combustion refers to a combustion mode in which natural gas is fully mixed with air according to a certain proportion before combustion and air is no longer needed to be supplied during combustion.
The difference between ordinary gas-fired boiler and fully premixed low-nitrogen condensing boiler lies in whether air and natural gas are mixed before or after entering the burner.
Today, there are two main types of green boilers used in different industries: biomass boilers and condensing boilers. Each of these operates in completely different ways to reduce your carbon footprint.
Biomass Boilers
Biomass boilers operate by burning wood and other renewable organic materials to produce heat. There are automatic biomass boilers that control the amount of air and fuel that is used, making them even more efficient. To keep this boiler running, owners will need ample ...
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
