Improve The Thermal Efficiency of Industrial Boilers

The higher the exhaust gas temperature of the boiler, the greater the heat loss of the exhaust gas, so reducing the exhaust gas temperature is a good way to improve the thermal efficiency of the boiler. In order to reduce the flue gas temperature, most factories will choose to equip flue gas waste heat recovery devices, such as economizers

Removal of Elemental Mercury from Flue Gas Using …

2020-3-31 · Iris sibirica biomass (ISBM) used for cobalt (Co) pollution remediation was prepared by one-step pyrolysis and employed to remove elemental mercury (Hg 0) from flue gas.Results showed that the ISBM pyrolyzed at 700 °C (ISBM700) exhibited good Hg 0 removal performance (about 86%) at 150 °C. The existence of NO and O 2 facilitated the removal of Hg 0, while SO 2 and water vapor inhibited it.

GASIFICATION – The Gateway to a Cleaner Future

2002-1-25 · The flue gas will be removed without coming in contact with the product gas. With this concept, it is possible to get a high-grade product gas without use of pure oxygen. In "real life" this process can be realized with two fluidized beds connected with transport lines or with an internally circulating fluidized bed. Figure 6.

Biomass waste-to-energy valorisation technologies: a

In pyrolysis, biomass is subjected to an optimal temperature of 700 °C in the absence of oxygen resulting in the production of pyrolysis oil (biooil), char and synthesis gas (Syngas). Syngas is a mixture of majorly CO, CO 2, H 2, H 2 O, CH 4, trace amounts of higher hydrocarbons such as ethane and propane, as well as various contaminants

Figure 5 shows a typical example of how the concentration of unconverted CO in the flue gas of the Chalmers boiler increases as the activity of the olivine bed increases. The addition of a continuous flow of 1.0–1.2 kg/h (i.e., 1 mg/kg dry fuel) of elemental sulfur to the bed immediately confers complete combustion of CO, while the CO

A method of decreasing the concentration of nitrogen oxides in a combustion flue gas in which a nitrogen reducing agent is introduced together with the overfire air to mixes with the products of primary combustion along with the overfire air. The nitrogen agent reduced NOx as it passes through the temperature regime that is optimum for the NOx reduction as overfire air and flue gas mix.

International Journal of Greenhouse Gas Control, •

Oxy-fuel combustion needs recycled flue gas to reduce furnace temperature for material protection. The enhanced CO2 alters coal devolatilization behavior. Devolatilization (albeit very quick) determines the whole life of coal in furnace, and thus it is essential to clarify the effects of CO2 gas media on coal devolatilization behavior.
