Grate firing was the first combustion system used for solid fuels. It now is used mainly for burning waste and biomass, but also for smaller coal furnaces.
- Capacities 0.3 to 175 MWth in industry and CHP
- Fuel fired per grate area 1-2 MW/m2, maximum grate area 100 m2
- Grates are typical only suitable for coarse particles, for fine particles a spreader is required, increases max. capacity
- Primary air through the grate (also used for cooling) and secondary air

Famous quotes containing the words grate and/or firing:
“I had rather hear a brazen canstick turned,
Or a dry wheel grate on the axle-tree,
And that would set my teeth nothing on edge,
Nothing so much as mincing poetry.
‘Tis like the forced gait of a shuffling nag.”
—William Shakespeare (1564–1616)
“The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.”
—Ralph Waldo Emerson (1803–1882)
