“…Srivastava et al [40] acknowledge that optimizing energy consumption will minimize harmful emissions to the environment. At the same time, it is reported that adjusting the solid fuel circulation time and the height of the fuel loading chamber will reduce the emission values [9].…”

In this study, an automatic solid fuel control algorithm has been developed that provides maximum heating with minimal solid fuel waste in boiler systems. With the algorithm developed using the Atmega16 microcontroller, motors such as stoker, fan, water pump used in boiler control and features such as boiler temperature, temperature sensor, water pump temperature are controlled. In addition to these features, operations such as fuel loading, waiting, fan speed adjustment can be performed with the help of the menu controlled by interrupt functions. The boiler control algorithm developed for real-time control of the system is programmed with the AVR C language. In the system in which the developed algorithm is used, a user-friendly panel with a 7-segment display has been developed to facilitate the work of the users. With the help of this panel, the user will be able to make all adjustments that affect the operation of the boiler in a very short time. As a result of experimental studies, an increase in the life span of the controlled boiler elements has been determined and an annual fuel saving of approximately 20% has been achieved compared to conventional boiler control systems.

Energy drives human life and is crucial for continued human development. It is the convertible currency of technology. Without energy the whole fabric of society would crumble. Global demand for energy is rapidly increasing with increasing human population, urbanization, and modernization. This growth is projected to rise sharply over the coming years in developing countries. The world heavily relies on fossil fuels to meet its energy requirements -oil, gas, and coal are providing almost 80% of the global energy demands. Oil and natural gas prices are continuously rising, due to the rapid worldwide increase in their consumption. Coals, covering about 65% of the proven fossil fuel reserves and being widely distributed throughout the world, provide stability in price and availability and will therefore play a major role in the global energy system in the coming decades. Furthermore, given the energy crisis, the development and use of renewable energy sources is one of the key challenges in the shorter and medium term to substitute fossil fuels, to provide commercially attractive options for meeting specific energy service needs, and to mitigate greenhouse gas emissions. Biomass, including all kinds of materials that were directly or indirectly derived not too long ago from contemporary photosynthesis reactions, such as vegetable matter and its derivatives, is a widely dispersed, naturally occurring carbon resource with great energy potential. It is also considered as a CO 2 -neutral energy source. The simple act of burning biomass to obtain heat and often light is one of the oldest biomass conversion processes known to mankind.Thus, the study of coal and biomass combustion for power generation or heating processes is of extreme importance, if we are to conserve our sources of energy, while achieving the required environmental goal efficiently and reliably in a world of increasing population and energy needs. This chapter provides a survey of the technologies that are either available or are being developed to enable all solid fuels to be used cleanly and with greater amenity.

The United Nations Framework Convention on Climate Change (UNFCCC) states that Indonesia is committed to contributing to global climate change solutions. The government will also continue to encourage the development of a number of renewable energy (EBT)-based power generation projects. This is based on the use of renewable energy which is still low, namely around (1.9%) 8215.5 MW. Meanwhile, the potential for EBT to become energy can be around 443,208 MW. One source of EBT in Indonesia that can be utilized is Biomass. Co-firing of biomass is a relatively cheaper option and does not require investment in new power plants. However, Co-firing combustion has several aspects that need to be studied, such as temperature combustion and the generation of gas emissions. Therefore, this study aims to determine the temperature and the emissions resulting from co-firing of palm kernel shell biomass. This research was conducted using the Computational Fluid Dynamics method on stoker boiler model. The test parameters of the research was the maximum and average temperatures in the furnace, and the average and maximum fractions of CO2, SO2 in the stoker boiler furnace. From the research conducted, it was found that the resulting combustion temperature decreased as the co-firing fraction of the biomass increased. However, CO2 gas emissions increased and SO2 decreased with increasing fraction of co-firing biomass which showed a decrease in harmful gas emissions and complete combustion that occurred in the furnace.
