EHV Substation/Terminal Bay Extension HV/EHV Transmission Line Distribution System Strengthening Works (RAPDRP / IPDS / HVDS Projects)
Biocoal’ is solid fuel from biomass. Biomass waste is converted from a bulky, low energy high moisture content to having higher energy density, low moisture, mostly lower ash content and having very low harmful gases emission like SO2 & NO2. Pellets/briquettes of biocoal are made from processed agricultural refuse. The process of converting agricultural waste to solid fuel is net non-polluting. The application of coal, wood, furnace oil and other conventional fuels in industrial as well as in domestic practices can be readily substituted with the use of biocoals.
Loose Biocoal has very low specific density of just 60 to 180 Kg/m3 but in the briquette form has high specific density (1200 Kg/m3) and bulk density (800 Kg/m3). Costs for transportation of biocoal and loading/unloading are much lesser and storage requirement is also substantially reduced.
India produces huge quantity of biomass waste which are burnt or allowed to degrade. Biocoal will add value to agriculture produce and save the country valuable foreign exchange and reduce pollution. Net pollution from biocoal is zero unlike mineral coal.
KSA in technical collaboration with Aarath Engineers has designed a process to convert various types of biomass into biocoal. We are in process of setting up one 12000t per month plant in Manamadurai.
