brief explain water tube boilers

Furnace excess air ratio control is an important indicator of gas brief explain water tube boilers furnace combustion process. For Stoker, requires excess air ratio at the outlet of the furnace is generally between 1.3-1.5, the amount of flue gas flowing leakage calculation for each section of the flue, exhaust excess air ratio should be at 1.8 to 2.0.

FGR refers to flue gas recirculation techniques, by using external flue gas recirculation and the inner loop is provided, withdrawing part of flue mixed with the combustion air, and then into the furnace through a burner, not directly involved in the combustion, by reducing the flame temperature reached reducing combustion temperature and oxygen concentration effects, thereby achieving the purpose of reducing NOx generation. Second, a low nitrogen higher thermal efficiency of the brief explain water tube boilers

After use throughout the winter, the Central Conservatory of Music give us feedback, six V6-99 fully meet the heating needs of the school. And brief explain water tube boilers fuel and water requirements are not high, urban water and low-pressure natural gas combustion can operate. The most important point is that nitrogen oxide emissions are very low and very happy to recommend it to others to do the brother of boiler units. --customer feedback
