提出了超临界锅炉汽温调节和煤水比调节应注意的几个主要问题。
Some vital points to be heeded concerning steam temperature regulation and coal water ratio in supercritical boiler are mentioned.
更好的方法是使煤和水发生反应，产生一种二氧化碳和氢气的混合物。在这种混合物中二氧化碳含量比一般电厂废气中的更高，所以更容易分离。
Better still, the coal can be reacted with water to produce a mixture of CO2 and hydrogen in which the carbon dioxide is much more concentrated than in normal flue gas, so it is easier to scrub out.
