North American coal deposits were first discovered by French explorers and fur traders along the shores of Grand Lake in central New Brunswick, Canada in the 1600s. Coal seams were exposed where rivers flowed into the lake and was dug by hand off the surface and from tunnels dug intoRead More →
Thus the volatile matter is an index of the gaseous fuels present. Typical range of volatile matter is 20 to 35%. Proportionately increases flame length, and helps in easier ignition of coal. What is volatile material? A volatile substance can be defined as (1) a substance that evaporates readily atRead More →
HydroMOR can also process iron ore fines or mill scale, which are considered lower-value than premium lump iron ore and often considered waste. So, steel can be made without metallurgical coal. And green steel made from renewable-generated hydrogen may one day be affordable. Can steel be made with renewable energy?Read More →
That is miles upon miles between the earth’s surface. Due to the immense pressure that is present in this part of the earth, as well as the extreme temperatures, a diamond gradually begins to form. The entire process takes between 1 billion and 3.3 billion years, which is approximately 25%Read More →
Toilets. You’ll find public toilets on Lower Stable Street (south), including two accessible WCs with a family room and at the Western Coal Drop (north) there is one accessible WC and family room. What are Coal Drops? A coal drop is an elevated railway track designed to allow material toRead More →
A non-caking coal is that coal which on heating in absence of air doesn’t from a coherent mass of residue. … A coking coal is that coal which on heating in absence of air leaves a solid residue. A non-coking coal also leaves a solid coherent residue which may notRead More →
What is difference between thermal coal and coking coal? Thermal coal and coking coal are two such types of coal. The key difference between coking coal and thermal coal is that coking coal is mainly used to produce high-quality coke, whereas thermal coke is important in producing electricity. What typeRead More →
Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast. IsRead More →
Use the accompanying fact sheet and differentiated flash card activity to explore the different properties and uses of four allotropes of carbon – diamond, graphite, graphene and buckminsterfullerene. What are the allotropes of carbon? Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are threeRead More →
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. DoesRead More →
