Review of experimental methods to determine spontaneous combustion susceptibility of coal – Indian context

This paper presents a critical review of the different techniques developed to investigate the susceptibility of coal to spontaneous combustion and fire. These methods may be sub-classified into the two following areas: (1) Basic coal characterisation studies (chemical constituents) and their influence on spontaneous combustion susceptibility. (2) Test methods to assess the susceptibility of a coal sample to spontaneous combustion. This is followed by a critical literature review that summarises previous research with special emphasis given to Indian coals

Experimental and Numerical Study of Water Mist Fire Suppression System Effectiveness on Shielded Fire

This study aims to investigate the effectiveness of water mist on suppressing a shielded fire. Full-scale experiments are carried out in a partition room of (lxwxh) 2x2x2.5 m size. Five water mist nozzle which consist of two type nozzle was used, high flow (fogjet) nozzle installed at top center of the room and fine spray nozzle installed at each side of room at high 1.5 m from ground. The pressure of water mist system was maintained at 20 bar which correspond to 2.6 lpm of water flow rate. Wood crib of 6.5 x 6.5 x 6 cm size was used as the fuel source. The obstruction used as a fuel shield has table like form with 40 x 40 cm cover area and 0.5 m height. The location of fuel source and fuel shield was varied (1) fuel source and shield at centre of room, (2) fuel source at one side of shield and the shield at centre of room, (3) fuel source and shield at corner of room, and (4)) fuel source at one side of shield and the shield at corner of room. Numerical simulation using FDS 6.5.3 was also performed to validate the use of FDS and get better understanding of the phenomena. The results showed that water mist was able to extinguish the fire around 20 s, 16 s, 30 s, and 24 s for scenario 1, 2, 3 and 4 respectively. It is also observe that the mist distribution around the shield and cover area of the shield play a role on the capacity and time needed of water mist to extinguish the fire

Bantengan: Kadigdayaan Seni Tradisi

Bantengan merupakan bentuk seni pertunjukan rakyat Jawa Timur, warisan leluhur tanah Jawa yang erat dengan budaya agraris. Hampir seluruh pelaku bantengan merupakan petani penggarap. Bantengan menggambarkan pertarungan antara banteng melawan musuhnya, yaitu macan dan monyet. Banteng melambangkan kebaikan (kekuatan, keadilan, sekaligus melambangkan kemakmuran) yang dapat mengalahkan keburukan (macan dan monyet). Permainan bantengan menggunakan kekuatan magis untuk memanggil ruh leluhur, roh binatang atau dhanyangan dan memasukkan kedalam tubuh pemain bantengan sehingga pemaindalam kondisi in trance (ndadi). Permainan dikendalikan pawang atau pamong (sesepuh dan pendekar). Buku ini memfokuskan diri pada kehidupan bantengan di daerah Kota Batu dan sekitarnya, yaitu daerah Pujon karena populasi bantengan meningkat pesat. BAhasan dalam buku ini antara lain mengulas tentang: sejarahbantengan, masyarakat bantengan, gebyak bantengan, ngarak bantengan, revolusi bantengan, dll. Kata kunci: seni tradisi, bantengan, seni pertunjuka
