  生物质燃料在排风和二次风中,在炉膛内受到高温烟气和排风播种作用的强烈扰动,迅速产生大量的还原性大气,并释放出满足负荷的热量。
  In exhaust and secondary air, biomass fuel is strongly disturbed by high temperature flue gas and exhaust sowing in the furnace, which rapidly generates a large amount of reductive atmosphere and releases heat to meet the load.
  生物质热风炉高效燃烧形成的条件如下:
  The conditions for high efficiency combustion of biomass hot blast stove are as follows:
  (1)篦孔畅通,倾角合理,停止间隔、振动频率、振动时间适宜。
  (1) The grate hole is smooth, the inclination is reasonable, the stop interval, the vibration frequency and the vibration time are suitable.
  (2)第一次风穿透燃料,底部火风充足,呈微沸腾状。
  (2) The first wind penetrates the fuel, and the bottom is full of fire and wind, which is slightly boiling.
  (3)二次风角合理,足以抑制管柱上的火灾。
  (3) The secondary air angle is reasonable enough to suppress the fire on the pipe string.
  (4)适宜氧含量为3%~6%,秸秆燃料含碳量低、挥发性大、灰分大、燃料空隙大、燃尽时间长,需要富氧燃烧。
  (4) The suitable oxygen content is 3%~6%. The straw fuel has low carbon content, high volatility, high ash content, large fuel gap and long burnout time, which requires oxygen-enriched combustion.

  (5)根据生物质燃料的干燥程度,利用点火风尽可能提高燃料的预热温度,形成炉排火灾的高端。
  (5) According to the drying degree of biomass fuel, the ignition air is used to increase the preheating temperature of the fuel as much as possible to form the high end of the grate fire.
  (6)炉温足够高,一般情况下,炉温在800℃以上可以建立连续的高强度燃烧。
  (6) Furnace temperature is high enough. In general, continuous high-intensity combustion can be established at above 800 C.
  (7)保持燃油湿度低于20%,降低点火温度。
  (7) Keep fuel humidity below 20%, and reduce ignition temperature.
  (8)燃料灰分应控制在20%以下,以改善燃尽。
  (8) Fuel ash should be controlled below 20% to improve burnout.
  (9)炉排两侧燃料分布在中、高、低状态,厚度适宜。
  (9) Fuel on both sides of grate is distributed in medium, high and low state, and the thickness is suitable.
  (10)燃料应尽可能细,粒度适中,与氧气保持良好的结合面。
  (10) Fuel should be as fine as possible, with moderate particle size and good combination with oxygen.
  (11)保持连续进给,防止堵塞进给。
  (11) Maintain continuous feeding to prevent blockage of feeding.
  (12)一次风和二次风的比例为3:7或4:6,根据不同的材料选择风速,使风速适合于燃料燃烧。
  (12) The ratio of primary air to secondary air is 3:7 or 4:6. The wind speed is selected according to different materials to make the wind speed suitable for fuel combustion.
  (13)二次风及时进入,混合炉内气体混合,使炉内烟气涡旋,延长了悬浮粉煤灰和粉煤灰燃料在炉内的行程,进一步降低了粉煤灰和粉煤灰燃料。
  (13) Secondary air enters in time and gas mixes in the mixing furnace, which makes the flue gas swirl in the furnace, prolongs the travel of suspended fly ash and fly ash fuel in the furnace, and further reduces the fly ash and fly ash fuel.
  (14)选用木质或竹材生物质颗粒燃料可提高热风炉的燃烧效果!
  (14) Choosing wood or bamboo biomass pellet fuel can improve the combustion effect of hot blast stove.
