coal boiler flue gas governance design

Design standard for flues and ducts? - Boiler and Pressure

Estimated Boiler Performance and Expected Plant Performance. Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency.

• 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

Jul 05, 2009 · Coal Analysis for Boiler Designers - Hydrocarbon fuels are the major source of energy for power and process steam generation, and coal takes a major share in this. Boiler furnace design will depend more on fuel characteristics, and further heat transfer surface sizing will depend on furnace outlet temperature. Furnace Size Varies for Gas, Oil and Coal Firing - Furnace sizing is a very important for a successful boiler design. The variation in boiler …

H. Widell, in Biomass Combustion Science, Technology and Engineering, 2013 Furnace design. Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.
