Fuel characteristics of biomass boiler - FAQ - XinLi Boiler

Sep 17 2020 · The oxygen content of biomass significantly exceeds that of mineral coal which facilitates the ignition of biomass. Sulfur: The sulfur content in the BMF material is lower and the environmental protection characteristics are good. There is no need to set the denitration equipment when it is ignited.

OxyFuel combustion of Coal and Biomass DTU Research

The oxyfuel combustion process introduces several changes to the power plant configuration. Most important the main part of the flue gas is recirculated to the boiler and mixed with pure oxygen. The oxidant thus contains little or no nitrogen and a near-pure CO2 stream can be produced by cooling the to remove water.

Experimental investigation on flue gas emissions of a ...

Feb 23 2010 · When the biomass boiler is in operation at its design load with a flue gas O 2 concentration of 6% the dry flue gas flow rate was estimated to be 550 l (at 15°C and 1 atm)/min. The amount of CO and NO x emitted when the boiler is actually in operation could be estimated by using the measured emission concentrations and the estimated dry flue gas flue flow rate.
