Biomass energy: green or dirty? Physics World

Jan 08, 2020 · But as environmentalists cheer the good news and policy-makers give themselves a pat on the back, a terrible truth has come to light: biomass power plants a key renewable-energy source and one of the main replacements for coal-fired power are emitting more carbon dioxide from their smokestacks than the coal plants they have replaced.

Steam locomotive - Wikipedia

How a steam locomotive works, in 100 words ; Coal or oil is directed into the firebox (item 27 in the large diagram below), where it burns at high temperature. The firebox is surrounded by water in the boiler, and many tubes (28) extend from the firebox's front along the boiler barrel (29). Very hot gases travel through these tubes and up the smokestack/chimney (33).

Biomass briquettes - Wikipedia

Biomass briquettes are a biofuel substitute to coal and charcoal. Briquettes are mostly used in the developing world, where cooking fuels are not as easily available.There has been a move to the use of briquettes in the developed world, where they are used to heat industrial boilers in order to produce electricity from steam.The briquettes are cofired with coal in order to create the heat

Pellet fuel - Wikipedia

Pellet fuels (or pellets) are biofuels made from compressed organic matter or biomass. Pellets can be made from any one of five general categories of biomass: industrial waste and co-products, food waste, agricultural residues, energy crops, and virgin lumber. Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust and related industrial wastes from
