Boiler Bahan Bakar Solar Biodiesel-Light Oil Burner
Boiler Machines – Technological advances have a very significant impact on human activities, especially in the industrial sector. Various kinds of technological developments are carried out to facilitate human performance, so currently, there are many types of industrial equipment that have the same purpose but have different ways of working, including boilers. After the previous post, we discussed the meaning of boilers and their main parts, this time we will try to review the types of boilers and their advantages and disadvantages.
What are Boilers?
A boiler or boiler is a closed device used to heat water to produce steam, the heat from burning fuel in the boiler will be transferred to the water medium flowing in the pipes, when the water temperature has reached a certain temperature it will occur. evaporation. So that it can be interpreted that a boiler is a tool used to make steam, as we know steam can be used to drive a turbine in a power plant and function as a temperature regulator in a petroleum distillation column.

Before we discuss further boiler technology at this point, it would be nice if we knew in advance the type of boiler that was first used. This boiler is called a Pot Boiler or Hycock Boiler which has the simplest form in history and was first introduced in the 18th century. This boiler has a large volume of water but can only produce steam at low pressure, using wood and coal as fuel. that’s a little explanation of the ancient boiler that was successful in its time.

Boiler Type
Boiler engine types can be distinguished from various things such as characteristics, working methods, types of pipes, and the fuel used. Each type of boiler has its advantages and disadvantages, as we have explained below:
Boiler Type Based on Tube Type (Pipe):
1. Fire Tube Boiler
This boiler has two parts in it, namely the combustion tube and the barrel/barrel which contains the fluid. This type of fire tube boiler has the characteristics of producing a low amount of steam and a limited capacity.
The working principle: The ignition process occurs in the pipe and the heat generated is channeled directly to the boiler filled with water.
Pros: The installation process is quite easy and does not require special settings, does not require a large area, and has a low cost.

Weaknesses: Has a combustion chamber that is difficult to reach during cleaning, has a low steam capacity, and is less efficient because a lot of heat is wasted.
2. Water Tube.
Having construction that is almost the same as the fire pipe type, this type also consists of a pipe and a barrel, the only difference being that the side of the pipe is filled with water while the side of the barrel is the place for burning. A characteristic of this type is that it produces relatively large amounts of steam.
Working Principle: The ignition process occurs on the outside of the pipe, so the heat will be absorbed by the water flowing in the pipe.
Pros: It has a large steam capacity, relatively higher efficiency and the furnace is easy to reach when cleaning.
Disadvantages: The initial investment cost is quite expensive, requires a large area of land, and requires additional components in terms of water treatment.
Based on the type of fuel
1. Solid Fuel
This type of boiler engine uses solid fuels such as wood, and coal, with characteristics such as fuel prices which are relatively cheaper and more efficient when compared to electric boilers.
Working Principle: Heating comes from the combustion of solid fuels or can be a mixture of several solid fuels (coal and wood) assisted by oxygen.
Pros: Fuel is easily available and cheaper.
Disadvantages: Burnt residue is difficult to clean.
2. Fuel Oil (Oil Fuel)
This type has fuel from the petroleum fraction, with the characteristics of having more expensive combustion raw materials, but has a better efficiency value when compared to other types.
Working Principle: Heating comes from the combustion of a mixture of liquid fuels (kerosene, diesel, residue) with oxygen and a heat source.
Pros: It has little combustion residue so it is easy to clean and the raw materials are easy to obtain.
Weaknesses: It has expensive raw material prices and expensive construction.
3. Gas Fuel
Has the type of natural gas with the characteristics of raw materials that are cheaper and have better efficient value when compared to other types of fuel.
Working Principle: Combustion yes This occurs because of a mixture of fuel gas (LNG) with oxygen and a heat source.
Pros: has the cheapest fuel and a better efficiency value.
Disadvantages: Expensive construction and difficult to source fuel, must go through distribution channels.
4. Electric
From the name alone, we certainly already know that the heat source of this tool comes from electricity, with the characteristics of a fuel that is cheaper but has a low level of efficiency.
Working Principle: Heating sourced from electricity supplying heat t.
Pros: Maintenance is simple and heating sources are very easy to find.
Disadvantages: Poor efficiency and low combustion temperature.
So many discussions about the types of boilers based on their work, hopefully, this article can be useful for those of you who need it, thank you.
