To verify technical data, research has been conducted on a 1025 t/h tangential firing boiler adopting this technology and a three-dimensional particle-dynamics anemometer (PDA) is employed on this prototype for measurement of the characteristics of two-phase gas/particle flows in the burner area. The distribution of the particle concentration and size distribution of the primary air, as well as the gas/particle velocity field were obtained. The experiments also measure the flowing characteristics of over-fired air (OFA) and secondary air. The results show that, with counter flow of fuel-rich jet technology, more particles can be injected into the high-temperature side in the furnace, the concentration of the particle is higher at the high-temperature side than that near the water wall, and the particle concentration of large particles is also lower near the water wall. The research shows that the counter-flow technology combined with overall air-staged technology of the tangential firing boiler can realize low NOx emission and high efficiency combustion and can prevent slagging on the surface of the water wall and high-temperature corrosion. | ||
