Today many boiler users use solid fuel
as an option for their fuel consumption, for example palm shells. palm shell (shell / shell) as fuel. Consideration of the use of this fuel, because palm shells are widely available in this country.
Oil palm plantations can be found on the islands of Sumatra, Java, Kalimantan and Sulawesi. Therefore, many company / factory owners use this shell waste as their boiler fuel. In fact, such as the island of Java where there are not many oil palm plantations, many companies use palm oil palm shells for environmental and financial reasons. Costs to be incurred as boiler fuel consumption are more economical compared to slar or gas, especially LPG. The second reason is that palm shells are usually used as a substitute for coal fuel, because the exhaust emissions released from the combustion chimney are more environmentally friendly compared to coal fuels with higher toxic chemical content. Apart from oil palm, there are also those who use coal,
To be able to use a palm oil shell, a boiler design with a furnace must be made. Unlike the boiler or thermal oil fueled with diesel / diesel or gas. The design of a boiler with a combustion engine / burner is simpler when compared to a boiler with a furnace, there must be a combustion chamber for this solid fuel fuel. Usually the design of boiler stoves can be entrusted to boiler makers, because they are more knowledgeable and experienced in terms of designing boiler furnaces with the right design. This is usually based on consideration of room efficiency, combustion speed or type of boiler itself.
Calories produced from burning palm shells can reach 4000 – 4500 kcal / kg, only a difference of about 500 – 1000 calories from coal fuel which is about 5,000 to 5500 calories. Another advantage is the price of shell fuel per ton far cheaper than coal. So that it will increase the value of the cost efficiency of boiler fuel expenditure.
Palm shell fuel types are very abundant available in Indonesia. In general, palm shells are the second largest fuel in use as fuel after coal is in the category of solid fuel.
