Condensation Of Flue Gases In Boilers

Condensation Of Flue Gases In Boilers

If strict accordance with methods to manipulate natural gas condensation of fluees in boilerss, boiler failure does not occur. But if human error or other reasons, is likely to make the boiler at risk, then we need an emergency shutdown, in order to ensure the safety of the boiler and operator.

How gas condensation of fluees in boilers automatic control of temperature: the traditional coal-fired boilers, the boiler worker is a job must be equipped, they must not only ensure the safe operation of coal-fired boilers, we have to maintain the operation of the boiler. However, new gas boiler has passed the automated control system, all-weather running unattended, then how to achieve it? In boilers with automatic control systems, built-in temperature sensors, which during operation is equivalent to our eyes, it is responsible for the case where the operation of the boiler on the boiler to the controller by way of data. For example, a boiler with a set temperature of 55 ℃, a temperature sensor in the boiler furnace temperature acquired at this time is 40 ℃ boiler runtime. After sending the temperature data to the controller determines the control temperature is far from the set temperature, so the controlled state of the burner fire continues to heat the water in the boiler.

After the above introduction, we can see that the papermaking process is also inseparable from the help of steam condensation of fluees in boilerss. The steam that industrial steam boilers can provide can meet the demand for thermal power in the papermaking process.

July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam condensation of fluees in boilers contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.

2018-10-31·Best Practices for Condensing Boilers ATE ANWORMER, .E. AVI RASS, .E., EMBER ASHRAE Boiler systems today are engineered to increase ef ciency and reduce operating costs. Condensing boilers are a popular option because they recover energy that otherwise would be discharged out the boiler stack, enabling them to achieve more than 90% ef -

Condensing boilers achieve a much higher efficiency |

In a gas-fired condensing boiler, the water is heated through the heat of combustion, just as with non-condensing boilers. The resulting flue gases are normally passed into the chimney. As a result, the energy contained in the flue gas is lost. However, condensing technology exploits these gases, which consist to a large extent of hot water vapour.

Boiler Gas Condensation -

2017-8-14 · Myths and methods for protecting boilers against flue-gas condensation. Neptune was the god of freshwater and the sea in Roman religion. Speaking of myths, there are some when it comes to protecting boilers against flue-gas condensation. This temperature is low enough to cause sustained flue-gas condensation within the boiler.

Consider Installing a Condensing Economizer

2014-5-20·exhaust gases is dependent upon the hydrogen content of the fuel, the fuel firing rate, the percent of excess oxygen in the flue gases, and the stack gas temperature. Consider a natural gas-fired boiler that produces 100,000 lb/hr of 100-psig saturated steam. At 83% efficiency, the boiler firing rate is about 116 MMBtu/ hr.

Condensing - MG-Flues

Condensing boilers are renowned for being more efficient than non-condensing boilers, as the flue gas is kept under 60 degrees Celsius for condensation to start. The more condensation the better, as this means the maximum amount of energy is being extracted from the gas.

Application of Gas Condensing Boilers in Domestic Heating

boilers is justified from the point of view of energy because they achieve higher thermal efficiency than traditional boilers. Condensation of water vapour occurs in the flue gases, whereby the heat released by condensation is used to heat the water in the boiler. How much water vapour will condense depends on the temperature to which the

Combustion Booklet 2013 (2013,

The flue gases produced from condensing boilers are at a much lower temperatures than those of non condensing boilers to the extent that the water vapor in the flue gases condenses, thus releasing their latent heat and increasing efficiency of the boiler.


Condensing technology recovers the condensation heat retained latently in flue gases, that is a part of energy that normally disappears up the chimney in other heating systems. Thanks to lower fuel consumption and lower heating costs, condensing boilers usually pay for themselves in few years, reducing costs up to 20% in comparison with
