Dedicated to Professor Rüdiger Lange on the occasion of his 65th birthdayBiomass is an important energy source for decentralized power generation. The combination of a two-stage thermochemical conversion unit with an inverse Brayton cycle (IBC) is the subject of current research activities. Several advantages are expected compared to commercially available concepts. A commercially proven turbocharger from the automotive industry is used for the IBC unit. No cost-intensive gas cleaning is required due to an almost dust-and tar-free biomass conversion. The influence of the feedstock characteristics on the thermochemical conversion, the emissions, and the overall plant performance is subject to process optimization studies. Furthermore, validation of the concept is the target of a demonstration phase planned for a later stage of the research activities.

“…Simanjuntak, dkk (2015) berhasil mendapatkan nilai pembakaran biomassa jenis serbuk kayu sebesar 7 MJ/m 3 dengan menggunakan reaktor fluidized bed jenis sirkulasi internal [2]. Nilai CV dari biomassa sebesar ini sudah lebih dari cukup untuk digunakan sebagai bahan bakar pada mesin-mesin pembakaran dalam, motor bensin ataupun diesel [3] dan mesin pembakaran luar seperti turbin gas [4,5]. Namun teknik gasifikasi ini mempunyai kelemahan dalam hal perlakuanatau treatment biomassa sebagai bahan bakar.…”

Kombinasi antara reaktor pembangkit energi panas dari sumber energi terbarukan dan mesin pembangkit tenaga menggunakan mesin Stirling atau disebut cogeneration menjadi sebuah teknologi yang menjanjikan dalam menjawab tantangan penyediaan energi masa depan dari sumber energi terbarukan khususnya sumber energi dari biomassa. Tujuan artikel ini adalah memberikan review secara teoritis dan analitis bagaimana sebuah mesin Stirling yang terintegrasi dengan reaktor pembakaran biomassa mampu menghasilkan tenaga. Artikel ini juga bertujuan untuk memberi pemahaman yang lebih mendalam kepada mahasiswa yang sedang mempelajari mata kuliah khususnya terkait konversi energi termal. Banyak mesin-mesin termal yang dibicarakan dalam ruang kelas perkuliahan, namun itu semuanya secara sendiri-sendiri. Namun di dunia industri yang menggunakan mesin-mesin termal bahwa sistem termal tentunya adalah gabungan dari mesin-mesin termal yang bekerja secara bersama-sama. Implementasi rumus–rumus dasar, asumsi–asumsi yang digunakan untuk menganalisis suatu peralatan teknik yang melibatkan suhu, tekanan, dan aliran yang berkaitan dengan mesin termal lain dalam satu sistem akan membuat pemahaman para mahasiswa akan semakin baik dan mantap.

“…This biomass, converted into gas, which is called syngas [5,6], through the gasification process for sustainable bioenergy [7,8] and with additional treatment, could be utilized as an alternative fuel in a stationary engine for local electricity production and significantly contribute to socio-economic development in rural areas. Numerous works have reported on syngas as an essential fuel in several types of engines, including diesel engines in dual-fuel mode [9][10][11][12][13][14][15][16][17][18][19][20]. Despite its low energy content and the variability of its composition over time, especially for small installations, syngas has been found to be a good fuel for diesel engines operating in dual-fuel mode, since the engine maintains its performance and efficiency at high loads and is environmentally friendly.…”

Characterization, at Partial Loads, of the Combustion and Emissions of a Dual-Fuel Engine Burning Diesel and a Lean Gas Surrogate

For decentralized power generation in West Africa, gas from a small biomass gasification unit can be used as the main fuel in a dual-fuel engine with diesel as the pilot fuel. To study the combustion in this type of engine (Lister Petter), experiments were conducted with a surrogate gas composed of liquefied petroleum gas and nitrogen (LPGN2), the energy context of which is similar to that of syngas. The tests were conducted at different loads and for different diesel substitution rates. The combustion analysis showed that the LPGN2 mixture had an overall behaviour similar to neat diesel, while the pressure peaks were lower in dual-fuel mode. The results also indicated a longer ignition delay and a pronounced diffusive combustion phase leading to a lower indicated mean effective pressure with gas. The fuel efficiencies remained low in both mono- and dual-fuel operation. The relative instability of the combustion in dual-fuel mode gave rise to an increase in the coefficient of variation (COVIMEP). Compared to neat diesel, the engine running at low loads in dual-fuel mode showed higher emission levels of CO, a slight reduction of 2.5% of CO2 and a substantial decrease of 73% for nitrogen oxides.
