- v. To feed insufficiently.
- v. To supply (an engine) with fuel from the underside.
Century Dictionary and Cyclopedia
- Noting apparatus which feeds or supplies fresh material from below; specifically, noting a form of mechanical feeder for fuel of boiler-furnaces, designed for bituminous coal rich in volatile components. The coal is fed through a tubular channel and enters the burning area from under the bed of ignited fuel. The gases first distilled off must pass up through the glowing bed above them and become heated enough to unite with oxygen and burn with little smoke. After the coking is completed the solid carbon begins to glow and burn, and its combustion is completed as it reaches the top of the fuel-bed and rolls outward toward the sides of the grate area proper. This feeder is particularly well adapted for pitchy or fat coals.
