fireFIGHTINGthing





Fire fighting is a highly skilled operation and most medium and large firms have properly trained teams who can contain the fire locally until the professional brigade arrives. The best way you can help is to learn the correct fire drill, both how to give the alarm and how to leave the building. It requires only one person to panic and run in the wrong direction to cause a disaster.
In an emergency never lose your head and panic.

Smoke is the main cause of panic. It spreads quickly through a building, reducing visibility and increasing the risk of falls down stairways. It causes choking and even death by asphyxiation. Smoke is less dense near the floor: as a last resort crawl. To reduce the spread of smoke and fire, keep fire doors closed at all times but never locked.
The plastic materials used in the finishes and furnishings of modern buildings give off highly toxic fumes. Therefore it is best to leave the building as quickly as possible and leave the fire fighting to the professionals who have breathing apparatus.
Saving human life is more important than saving property


about Solidarity Poreper



sebenarnya lambang ini adalah lambang anak mesin yang dipakai pada saat Yell boys
Lambang ini divisualisasikan denngan menggenggamkan tangan kemudian menyelipkan ibujari di antara jari tengah dan jari telunjuk
Sepintas memang terkesan ngawur, karena tangan seperti itu artinya...mm, you know..
Tapi itu berarti kita tidak open-minded. Karena langsung mengartikan seperti itu. Maka dari itu, anak mesin justru mengartikan sebagai simbol open mindedness.

Yah, solidarity forever berarti kita akan selalu bersama sampai selamanya
(teori doang)
Semua juga pinginnya selalu kompak, tapi ya keluarga juga buntut2nya yang menjadi ganjalan

Sekian dan terimakasih

BOILER

This project costs Rp 891 514 700,-. The user is LEMIGAS (some kind of Lembaga Minyak & Gas; i don't know exactly, due to relation with the renewable energy division only).
Designed capacity is power plant that generate 3 kilowatt. This power can turn 6 lamps of 500W each. Not much, because it's just research purpose only. This power plant fueled by coconut shell charcoal, which have about 6000 cal/kg. So this charcoal burn the boiler, then boiler generate steam, thus steam rotate turbine, turbine rotate generator, and..... eng, ing, eng...Electricity!


Well... this boiler we made at
 Bandung. This's our first, so it's very "book-minded".
Two bottom tubes called bottom header. The small one called riser.
Above the riser called top header. And the top is called steam drum,
being used to separate water from steam.
So the steam that enter turbine is dryer, which make turbine life longer.

This is used to feed the charcoal under the top header & between the bottom, header. Charcoal will burned on the stair-like one. It can move forth&backward, while it burns. This will piling up the ash in the front bottom side, which make us easily to pick up the ash.


Thus, of course we build its furnace, so the heat focused on boiling the water inside. We used fireproof brick, SK 34, which means, could resist 1400 centigrades of heat. To generate the
 desired steam flow, the temperature inside must fulfil the designed temperature.
