so mills make every effort to reduce consumption. According to CEPI4, "the paper industry has made important strides in reducing total energy use since 1973 and in increasing the fraction of energy provided from selfgenerated biomass sources. The paper industry is now the biggest user and producer of renewable energy sources".

The most significant airborne mercury discharge occurs through burning of coal (12 lb of Hg/1000 ton of pulp). The fuel use by the paperpulp industry may represent about 2% of the total coal burned and the industry's share in airborne mercury pollution amounts to just that. Paperpulp mills discharge only a very small amount of mercury (about ...

Pulp and paper mills using biomass boilers are facing the challenge of managing the resulting ash residues. It was estimated that the Canadian industry generated approximately 420,000 t/y of ash in 2013 (Elliott and Mahmood, 2015).Most of these power boilers combusted biomass (hog, pulp rejects, biosolids) with or without being supplemented with oil or gas.

Don't forget that a paper mill consumes massive amounts of energy, so you might have a boiler plant on site that receives coal or oil. Outbound products are typically shipped in insulated boxcars, since paper is very sensitive to moisture and temperature variations. I modeled a significantly compressed paper mill on my N scale layout.

Flambeau burns coal, biomass and highenergy wood pellets to generate electricity. Then it turns the waste heat from that process into highpressure steam that is used to produce an additional MW of electricity, meeting 27 percent of the plant's power needs. After being used for generation, the nowlowpressure steam is used to make paper.

To solve the problem of acquiring massive fault data, a method used for fault data generation is proposed in this paper, by which fault data samples can be generated by the fault simulation of a coal mill system model. The core lies in constructing a model of the coal mill system that can support fault simulation.

Power House boilers generally use coal, wood waste, black liquor, oil, natural gas, or a combination of fuels. The type of fuel used depends on the size of the mill and whether there's a pulping operation on site. Many mills have multiple different kinds of boilers on site and most include steam turbines to generate electricity.
