Analysis of the impact of hydrogen blended natural gas on combustion equipment
This article investigates the effect of natural gas blended with hydrogen on Combustion equipment.When the hydrogen blending ratio is within 30%,the variation of Wobbe index is small,which basically does not affect the combustion load and the performance of the gas appliance;Within a hydrogen blending ratio of 50%,there is a slight decrease in combustion air and flue gas under the same combustion load which basically does not affect the conveying capacity of the smoke and air system;The dew point temperature of the flue gas of hydrogen blended natural gas increases along with the risk of low-temperature corrosion.The latent heat of flue gas slightly increases with the same combustion load;Gas blended with hydrogen can significantly reduce CO2 and CO emissions,with less impact on NOx emissions from household gas appliances.However,further research should be conducted on the impact on low nitrogen burner of industrial boilers.
