BOILER
3 ways HEAT TRANSFER
1. Conduction - through a substance to another by actual contact.
Exampe - a metal spoon in a hot cup of drink.
2. Convection - transfer of heat within a substance by the actual fluid movement of the substance. Occurs only in liquids and gasseous like in the boiling of water.
3. Radiation - by heat energy waves which is travel in straight line at the speed of light.
Example the sun and earth.
Unit of HEAT
1. BTU British Thermal Unit
Amount of heat required to raise the temperature of one pound of water through 1 degree F.
2. KW Kilo Watt
3. K Calories.

Follow up 100x!
Sejak menyertai industri sawit sebagai cadet engineer Mac 2014, dalam masa 2 tahun 9 bulan saya dilantik menjadi incharge untuk kilang sawit berkapasiti 90 mt/hr dan memproses 350,000 mt ffb pada tahun 2007. Selain bertugas sebagai jurutera stim, saya mula meningkatkan skill pengurusan bermula tahun tersebut sehingga kini. Untuk rekod, saya telah menjadi pengurus sejak 9 tahun lepas dan telah menamatkan MBA pada tahun 2014.
Dalam semua pengalaman praktikal saya dan juga teori yang dipelajari, saya cukup terkesan dengan perkataan FOLLOW UP. Apa pun tugasan kita di sesebuah organisasi, follow up amat penting. Dalam teks, kita diingatkan dengan PDCA
PLAN
DO
CHECK
ACTION
Semua di atas cuma perlu lakukan sekali
PLAN, DO & ACTION
Namun, FOLLOW UP tidak cukup sekali, malah perlu lebih 100 kali atau 1000 kali !
Jika ada menjadi penyelia, mahupun jurutera, pengurus serta ceo sekali pun, FOLLOW UP amat penting. Jika ada cekap dalam FOLLOW UP, maka anda akan menjadi sangat efektif dan berjaya! Dalam apa jua yang anda lakukan.
Namun, jika ada lemah dalam FOLLOW UP, maka anda pegang jawatan apa pun, anda tidak akan berjaya!
Soalnya, apakah kaedah FOLLOW UP terbaik?
Sebenarnya tidak ada kaedah yang terbaik, yang paling penting adalah mencapai maksud atau tujuan sesebuah organsasi atau projek tersebut.
Gunakan segala kaedah yang ada.
Site visit.
Telefon.
Whatsapp.
Msg.
Mesyuarat.
Spot check.
Bertanya sumber lain seperti pekerja atau individu berkaitan.
Surat.
Email.
Yang paling utama adalah, proses tersebut MESTI DIULANG SEBANYAK 100 KALI ATAU 1000 KALI sehingga matlamat tercapai!
Ya kawan - kawan.
Jangan lupa FOLLOW UP!

Rupture Disc
A rupture disc, also known as a burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
A rupture disc, also known as a burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions. A rupture disc is a type of sacrificial part because it has a one-time-use membrane that fails at a predetermined differential pressure, either positive or vacuum. The membrane is usually made out of metal,[1] but nearly any material (or different materials in layers) can be used to suit a particular application. Rupture discs provide instant response (within milliseconds) to an increase or decrease in system pressure, but once the disc has ruptured it will not reseal. Major advantages of the application of rupture discs compared to using pressure relief valves include leak-tightness and cost.
Rupture discs are commonly used in petrochemical, aerospace, aviation, defense, medical, railroad, nuclear, chemical, pharmaceutical, food processing and oil field applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the rupture disc will burst. Rupture discs are very often used in combination with safety relief valves, isolating the valves from the process, thereby saving on valve maintenance and creating a leak-tight pressure relief solution.
Some models of gene gun also use a rupture disk, but not as a safety device. Instead, their function is part of the normal operation of the device, allowing for precise pressure-based control of particle application to a sample. In these devices, the rupture disk is designed to fail within an optimal range of gas pressure that has been empirically associated with successful particle integration into tissue or cell culture. Different disk strengths can be available for some gene gun models.
Although commonly manufactured in disc form, the devices also are manufactured as rectangular panels (rupture panels or vent panels). Device sizes range from under 0.25 in (6 mm) to at least 3 ft (0.9 m), depending upon the industry application. Rupture discs and vent panels are constructed from carbon steel, stainless steel, hastelloy, graphite, and other materials, as required by the specific use environment.
Rupture discs are widely accepted throughout industry and specified in most global pressure equipment design codes (ASME, PED, etc.). Rupture discs can be used to specifically protect installations against unacceptably high pressures or can be designed to act as one-time valves or triggering devices to initiate with high reliability and speed a sequence of actions required.
