Biomass feedstocks

energy

The main waste energy feedstocks are wood waste, agricultural waste, municipal solid waste, manufacturing waste, landfill gas and sewage sludge.

Biomass gasification

energy

Gasification is a process that converts biomass into gases. This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in the reaction.

Biomass heating system

energy

Biomass heating systems generate heat from biomass.

Biomass thermal conversion

energy

Thermal conversion processes use heat as the dominant mechanism to upgrade biomass into a better and more practical fuel.

Biomass to liquid

energy

Biomass to liquid is a multi-step process of producing synthetic hydrocarbon fuels made from biomass via a thermochemical route.

Biorefinery

energy

A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals).

Biosphere

energy

The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems.

Birefringence

energy

Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.

Bitter end

marine

The inboard end of a ship anchoring cable which is secured in the chain locker by the clench pin.

Bitts

marine

Vertical tubular steel posts; two of them are fastened to the rectangular base of a bollard.

Bitumastic

marine

Elastic cement used in place of paint to protect steel.

Bitumen

marine

A mixture of extremely heavy hydrocarbons obtained from residue refining process; used for road surfacing, roofing, etc.

Bitumen products

marine

Coaltar, creosote (coaltar and wood), coaltar pitch, antracene oil, coaltar naphtha. See also High heat tanker BITFLOWER, and Transport of bitumen products.

Bituminous coal

energy

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt.

Black body

energy

A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.

Black cargo

marine

Cargo banned by general cargo workers for some reason. For example because the cargo is dangerous or hazardous to health.

Black gang

marine

A slang expression referring to the personnel in the engine department aboard ship, that has an origin back to coal powered ships.

Black hole

energy

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.

Black petroleum oils

marine

Crude oil, furnace oil, fuel oil, also tar and asphalt.

Black start operation

energy

A method of starting or restarting power generation and supply to a power grid without use or reliance on external power supply.
