Fire ice produces a high amount of energy when burnt and its chemical reaction produces nothing but dioxide and water.

【翻译】可燃冰燃烧时产生大量的能量，其化学反应只产生二氧化物和水。

本句使用burnt 或burning 都正确。过去分词强调“被烧”；现在分词强调“自身燃烧”。请比较：

Part of the house was burnt in the fire. 房子的一部分被火烧毁了。

来自《简明英汉词典》

The stubble was burning in the fields.  地里的麦茬正在燃烧。

来自柯林斯例句

有的语法书，把及物动词叫做“他动词”，把不及物动词叫做“自动词”，是为了体现动词是否及物的用法特征。“他动词”需要跟宾语，有被动语态；“自动词”不跟宾语，没有被动语态。

decrease（下降）还有increase（提高）等动词，既是他动词（及物动词），也是自动词（不及物动词），也就是说，使用主动语态和被动语态都可以，主动语态强调了自身的动作，被动语态强调了人为因素或外在因素。在英语中，这样的动词有不少，例如：

I'm sure our dream will be translated into reality in future.

我相信，在未来我们的梦想会（被）变成现实。

If we redouble our efforts, our dream will translate into reality.

如果我们加倍努力，我们的梦想会变成现实。
