To heat that boiler, the damp, crumbly brown coal known as lignite — which is even more polluting than the harder black anthracite variety — burns in the presence

oxyfuel and precombustion scrubbing, so as to reduce the amount
of gas and pollutants to be scrubbed, as well as save on the energy penalty
of dealing with flue gas at atmospheric pressure.
