Abstract

Process for producing a briquette containing carbon carriers (2): mixing the carbon carriers (2) together with a binder system (3) with introduction of steam and the mixture obtained is pressed to form briquettes. At least one of drying carbon carriers (2), setting the temperature of the carbon carriers (2) to be mixed with the binder system before mixing or heat treating the briquettes after pressing by direct or indirect interaction with superheated steam. Waste steam is at least part of the steam introduced during mixing. An apparatus for carrying out such a process has such interaction with steam, from which a waste steam conduit leads and opens directly or indirectly into the mixing device.

Steam

Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated (water vapor) is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam".

Steam engine

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products.

Steam turbine

A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century.
