Abstract :Current issues related to fuels can be grouped under four headings. Today world is facing three critical problems: insert ignore into journalissuearticles values(1); high fuel prices, insert ignore into journalissuearticles values(2); climatic changes, insert ignore into journalissuearticles values(3); air pollution, and [1] heating value. Higher Heating Value insert ignore into journalissuearticles values(HHV); is one of the most important properties of fuels which explain the higher energy content and determine the efficient use of biomass and fossil fuels. HHV comes to design calculations or numerical simulations of thermal conversion systems for fuels. There are numerous equations proposed in the literature for calculating the HHV of fuels from the basic analysis data. The proximate and ultimate analyses of fuels are necessary for their efficient and clean utilization while the HHV of fuels determine the quantitative energy content of fuels. The proximate analysis can be applied by using the simple lab equipments. The HHVs nine biomass samples were correlated with their lignin insert ignore into journalissuearticles values(L%); contents. There was a highly significant correlation between the HHVs and L% of the biomass samples. The HHV insert ignore into journalissuearticles values(MJ/kg); of the biomass sample as a function of the L was correlated using the following Equation: HHV = 0.0979L + 16.292 for which the square of the correlation coefficient insert ignore into journalissuearticles values(R2); was 0.9321. The percentage of average error which was calculated using this Equation was equal to 3.3
