The boiler is a device shaped closed vessel used to heat water to produce steam (steam), heat from the combustion of fuel in the boiler will be transferred to the medium of water flowing in the pipes when the water temperature has reached a certain temperature it will happen evaporation. So can we interpret that the boiler is a tool that is used in letting steam, as we all know can be used to drive a steam turbine at a power plant and serves as pencaga temperature in the distillation column for petroleum.
Types of boilers
- Boiler Type based on Tube (Pipe):
- Fire Tube Boiler
In this boiler has two parts therein, namely the tube that is the site of combustion and bagin barrel / cask containing the fluid. The fire tube boiler types have characteristics that produce a low amount of steam and a limited capacity.
Principle Works: Process ignition occurs inside the pipe and the heat generated is delivered directly into the boiler containing water.
Pros: The installation process is quite easy and does not require special arrangements, does not require a large area and has a low cost.
Disadvantages: Have furnaces that are difficult to reach when they want cleaned, steam capacity is low and less efficient because a lot of heat is wasted.
- Water Tube.
Has a construction which is similar to the type of fire-tubes, this type also consists of pipes and barrels, which menbedakan only side pipe filled with water while the barrel was the scene of arson. Characteristics of this type is to produce a relatively large amount of steam.
Working Principle: The process of ignition occurs on the outside of the pipe, so that the heat will be absorbed by the water flowing in the pipeline.
Pros: Has a large steam capacity, niali relatively higher efficiency and furnace easy to reach when they will be cleared.
Disadvantages: The initial investment cost is quite expensive, requires a large area and requires additional components in terms of water treatment.
- Boiler Type based on Fuel Type
- Solid Fuel (Solid Fuels)
Type boilers using solid fuels such as wood, coal, with characteristics such as fuel prices are relatively cheaper and more efficiency when compared to an electric boiler. Working Principle: Heating comes from the combustion of solid fuel or it could be a mixture of some solid fuels (coal and wood) assisted with oxygen. Pros: The fuel is easy to obtain and cheaper. Disadvantages: Time burning difficult to clean - Fuel (Fuel Oil)
This type has a fuel from petroleum fractions, with the characteristics that have combustion of raw materials more expensive, but has a better efficiency values when compared primarily to the other. Working Principle: Heating derived from the combustion of a mixture of liquid fuels (kerosene, diesel fuel, residue) with less oxygen and a heat source. Pros: Has a little combustion residue so easy to clean and readily available raw materials. Disadvantages: Has the price of raw materials is expensive and has a construction which is expensive. - Fuel Gas (gaseous fuel)
Memiliiki type of fuel gas to the characteristics of the raw materials that are cheaper and better efficiency value when compared to other fuel types. Working Principle: The burning that occurs due to a mixture of fuel gas (LNG) with oxygen and the heat source.
Pros: has the cheapest fuel efficiency and better value. Disadvantages: costly construction and fuel sources are difficult to obtain, must go through the distribution channels. - Electric
From the name alone we must already learn that the heat source is derived from an electric tool, with the characteristics of the fuel which is cheaper but has a low efficiency level. Working Principle: Heating electricity supply comes from heat. Pros: Has the care that is simple and the heating source is very easy to obtain. Disadvantages: poor efficiency value and has a lower combustion temperature. So a discussion of the types of boilers based works, it is expected that this article can be useful for those who need, Thank you.
