一种新式蒸汽秸秆氨化炉

A New Type of Steam Chamber Used in Crop Steam Ammoniation

我国现有秸秆氨化炉能耗高，氨的利用率低。研制出一种新式蒸汽秸秆氨化炉。利用蒸汽从秸秆垛内部加热，秸秆升温快，可节能20％以上；采用水雾法回收氨气，可节省氨化剂10％左右；氨化秸秆的质量不低于现有氨化炉的水平，氨化稻草的粗蛋白含量提高了1．2倍。

A new type of ammoniation steam chamber is developed. The straw pile is heated with steam on the inside,the heating-up of straw pile goes rapidly and the energy requirement can be reduced nearly 20%. Adopting the water spraying method to recover the ammonia, the ammoniation dosage can be saved about 10%. The quality of amoniated straw is not lower than that of straw produced by the ammoniation chambers available on the market. The crude protein content of the ammoniated paddy straw is 2. 2 times as much.
