What is the effect of too low or too high furnace pressure on boiler operation?

If the furnace pressure is too low, the air leakage in the furnace and the flue will be intensified, the combustion will deteriorate, the combustion loss will increase, and even the combustion will be unstable until the fire is extinguished; If the furnace pressure is too high, the flame and high-temperature flue gas in the furnace will leak out, seriously affecting the safety of personnel and equipment.

SZS boiler adopts the design idea of large furnace, reduces the furnace volume heat load, and cooperates with professional burners to reduce NOx emission to ＜ 30mg / nm ³。 99% of the natural gas is methane (CH4), containing a large amount of hydrogen (H). The flue gas after combustion contains a large amount of water vapor. According to theoretical calculation, the water vapor in the flue gas accounts for about 18%. If the water vapor is condensed into water, the latent heat of vaporization is recovered, and the heat recovery is about 5%, the boiler efficiency can be increased to > 100%.
