19/06/2019 · Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation

The denitration performances of transition metal oxide oxygen carriers (OCs) including CuO/Al 2 O 3 MnO 2 /Al 2 O 3 and NiO/Al 2 O 3 for the gas-fired boiler flue gas were investigated. The results showed that NO was able to be reduced to N 2 through a direct reaction with the reduced OCs and at the same time the reduced OCs were converted to the oxidized OCs. .
01/04/2019 · Therefore, it is of great significance to develop a new low-temperature denitration technology for the gas-fired boiler flue gas,, . The SCR of NO x with CO, H 2, or hydrocarbons (i.e., CO-SCR, H 2-SCR and HC-SCR) based on noble platinum group metals (PGMs) has been generally applied for the automobile exhaust . However, it is not suitable for the field of gas-fired boilers due to the scarcity
Once the water vapour has been condensed, it turns into water. A condensing boiler, on average, creates around 2 litres of condensate water per hour, and it needs somewhere to go! By having a condensate pipe, the water is safely disposed of with the rest of the waste water, just like a sink or washing machine.
The methanol purification system is based on the unit operation of distillation (see Figure 1). The system includes two distillation stages. In the first topping stage, the compounds more volatile than methanol, such as H2S and ammonia, are removed in the vapour phase while the methanol, water and other less volatile compounds remain in
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
