Biocoal is ecofriendly, renewable energy fuel, economical cheaper contain high density. Government is providing tax benefit and incentives. It has easy mobility and transportation. Biocoal is solid fuel. The process of converting biomass to solid fuel is also nonpolluting. No addition of any binder/ chemical is required so it is natural.

Due to global warming, technologies reducing CO2 emissions in the metallurgical industry are being sought. One possibility is to use biocoke as a substitute for classic coke made of fossil coal. Biocoke can be produced on the basis of coal with the addition of substances of biomass origin. Blends for the production of biocoke should have appropriate cokemaking properties to ensure the ...

The average modified combustion efficiencies increased, and burning rates were about 20% faster. The combustion of biocoal briquettes can reduce greenhouse gases like 38% CO 2 and 45% CH 4 but also hazardous air pollutants like 52% CO, 45% NO, and 29% PM effectively in comparison with the bituminous briquettes.

Next, the ability of the biocoal production process or HTC technology to reduce pollutants in the environment is also a key driver for the adoption of biocoal. The firms are keen to look for alternatives that can perform the same function as coal while being environmentally friendly, unlike conventional coal.

Biocoal is produced by processing dry biomass in an inert environment (no oxygen) at high temperatures, a process referred to as pyrolysis. Depending on the temperatures and the characteristics of the end product, the process may also be referred to as torrefaction. This process is commonly carried out using an indirectfired rotary kiln.

The biocoal higher heating value (3032 MJ/kg) is in the range of the heating value of coal (3032 MJ/kg) used in the steel industries. Therefore, different biocoal production methods, such as pelletization, torrefaction, pyrolysis, hydrothermal carbonization, and steam explosion to produce biocoal, have been critically reviewed.

Biomass briquettes are a biofuel substitute to coal and charcoal. Briquettes are mostly used in the developing world, where cooking fuels are not as easily available. There has been a move to the use of briquettes in the developed world, where they are used to heat industrial boilers in order to produce electricity from steam.

Manmade or natural catastrophes cause disruptions of the entire demandsupply chain. Generally, it takes longer to make up the demandsupply chain and ultimately there is a loss of revenue and reputation. The major purpose of this paper is to evaluate the costbenefit and reliability of a biocoal manufacturing plant with deviation in demand. Whenever demand deviates, it affects the ...
