2013-12-9·Melting Coking High strength coke Experimentally produced coke with HPC (300 kg) Possible to increase coke strength without relying on blending coking. Enhanced compatibility with raw materials at the time when hydrogen reduction is put in practical use. HPC starts softening and melting at low temperatures below 300 oC.

2013-4-16·Environmental Aspects of Coal Combustion Residues from Thermal Power Plants They are fly ash, bottom ash, boiler slag and flue gas desulfurization (FGD) materials (wet or dry). The process of ash formation is influenced by the chemical composition of mineral matter agent, such as hydrated lime or quicklime with the presence of water in

2, carbon coking occurs resulting in degradation of the cell performance, or even deac-tivation of the nickel electrode due to a build-up of carbon on the nickel surface.2325 In order to avoid carbon deposition an additional reforming agent is therefore required. This could be air, steam or anode recycling containing CO 2 and steam. It was

Undesirable components of traditional coking processes are selectively cracked or coked in the coking vessel by injecting an additive into the vapors in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack (or coke) these undesirable components

This paper presents a process for adapting coal with high sinterability for use in small boilers in residential heating systems. This solution allows for the combustion of coals with an RI of 50 without causing negative effects (in terms of combustion stability) in typical burners used in heating devices.

Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.

FIELD: power engineering. SUBSTANCE: plant comprises a fuel-burning unit connected to a stack by means of a horizontal flue equipped with a gate, which is placed in the zone of adjacency of the horizontal flue end towards the stack, a circuit of cleaning of smoke gases, including a waste heat boiler, a smoke exhaust with a guide vane, at the same time the inlet of the circuit of smoke gases

So coal (as coke) is a reducing agent, a source of energy to drive the process and a source of carbon to incorporate in the steel. Alternative processes need to meet all three functions. This is why you have to do more than just substitute a different energy source. In New Zealand, the coking coal occurs on the west coast of the south island.
