The heating value or energy value or calorific value of a substance usually a fuel or food see food energy is the amount of heat released during the combustion of a specified amount of it The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditionsThe materials specifically covered by these standards can be in the form of lump coke pulverized coal bituminous coal coke and coal ash reformed gas and polishing and etching coal These standards also include the thermophysical property tables for methane ethane propane normal butane and isobutane

CWG carburetted water gas tar is less valuable than coal gasification tar as a feed stock Tar water emulsions are uneconomical to process due to unsellable water and lower quality by products CWG tar is full of lighter polycyclic aromatic hydrocarbons good for making pitch but poor in chemical precursorsLower calorific value / Net calorific value GCV NCV = The total amount of heat is produced when a unit quantity of the fuel is completely burnt and products of combustion are allowed to escape is known as NCV NCV = GCV 009H x 587 3 Explain proximate analysis Give its significance

q Tar Content in the gas by pyro gasification is nil The gas produced being at high temp has higher calorific value as such enhances gasification efficiency and lowers consumption of Coal/ MSW /Biomass q There is no effluent output in the process The washing of gas is done with re circulated water which separates out the solid impurities Coal Tar Lower Calorific Value 250tph river stone crushing line in Chile 200tph granite crushing line in Cameroon 250tph limestone crushing line in Kenya 250tph granite crushing line in South Africa 120tph granite crushing line in Zimbabwe 400tph crushing plant in Guinea Chat Online

Only 2 participants give lumped calorific values for tar One organisation uses 30 MJ/kg for all tar This is a low value and can only valid for tar with a high moisture or oxygen content ie typical for low temperature formation Molar weight for tar is used when estimating the density and the calorific value per mole or m³ for a tarry gasThe double stages Coal Gasifier has two upper and lower gas outlets which can output gas with different calorific valu The top gas contains tar and can be collected by electricity The gas is removed and recycled the bottom gas does not contain tar
