Abstract

Utilizing and improving the quality of Philippine indigenous coal is getting more important in order to sustain the country’s high dependence on coal over the next 10 years and to keep up with the country’s growing energy demands. Also, environmental problems and negative impacts of agricultural wastes are drawing more and more attention since the quantity of agricultural wastes has been rising rapidly all over the world. In the Philippines, sugarcane (Saccharum officinarum) bagasse has been identified as one of the significant contributor to the country’s biomass energy resource. Hence, in this study, coal blending technique has adopted as a proper approach to improve the quality of indigenous coal reserves while concurrently reducing and reusing agricultural wastes. This paper aimed to establish recommended blending ratios for Semirara coal, a sub-bituminous type of coal from Semirara Island in the province of Antique, Philippines and sugarcane (S. officinarum) bagasse. Proximate analysis, ultimate analysis, and calorific value were determined to characterize and understand the physical conditions and coal properties during combustion. Results showed that blending torrefied sugarcane (S. officinarum) bagasse with Semirara coal would generally improve its quality in terms of its combustion properties thereby making these combinations of coal and biomass advantageous.

Highlights

Coal is the largest source of energy in power generation industry worldwide that supports for the economy in both developed and developing countries
It can be established that Semirara coal blended with sugarcane (Saccharum officinarum) bagasse were additive based on its proximate analysis parameters
This paper aimed to establish recommended blending ratios for Semirara coal, a sub-bituminous type of coal from Semirara Island in the province of Antique, Philippines and torrified sugarcane (Saccharum officinarum) bagasse thru coal blending technique in order to improve the quality of indigenous coal reserves while concurrently reducing and reusing agricultural wastes

Summary

Introduction

Coal is the largest source of energy in power generation industry worldwide that supports for the economy in both developed and developing countries. Semirara coals are black in color, dull (not shiny), have higher moisture and volatile matter, and lower sulfur and fixed carbon content compared to other types of coal, referred to as sub-bituminous [4,5]. It is classified as second lowest rank of coals due to their lower calorific value [6,7,8]
