Coal-Fired Boiler Flue Gas Condenser

Coal-Fired Boiler Flue Gas Condenser Related Information

Coal-Fired Boiler - an overview | ScienceDirect Topics

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.

Challenges when Converting Coal-Fired Boilers to Natural Gas

• Flue gas recirculation (FGR) – Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler

Gas Condensing Boiler - Gas Fired Boiler, Gas Steam Boiler

Oct 30, 2020 · Gas condensing boiler is a steam boiler that condenses the vapor in the flue gas into water by condenser. It recovers the latent heat released during condensation process, and reuses such heat to achieve or above thermal efficiency. The flue gas temperature of conventional gas fired boilers is generally 160~250℃. The water produced during fuel combustion becomes vapor in the flue gas and …

Natural Gas Fired Boilers

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).
