Central Heating Boilers
Fire Tube Boilers
Fire Tube Boiler is a relatively old type of boiler, where hot combustion gas output is passed in a tube,
ad interim water is on the shell side, as a result heat transfer occurs which causes the water to turn into steam. Fire tube boilers are boilers that are inexpensive to use, relatively inexpensive, easy to operate and have good combustion efficiency. However, it is limited only to low capacities of around 2.5 tons/hour, using a pressure of 17.5 kg/cm2. The material used can be gas, fuel oil or solid fuel.
Packaged Boilers
As the name implies, this boiler is provided in package form by the boiler manufacturing industry. In addition, to operate the boiler, it is enough to add steam pipes, water pipes, fuel lines and electrical equipment. Generally, these boilers are in the form of a tube bundle, and their operating principle is the same as a fire tube boiler, which means they can transfer both radiant heat and convection heat well. Some features of compact boilers are:
Forced or induced draft systems produce combustion with good efficiency
Heat transfer by convection is relatively good due to the large number of small diameter tubes in this boiler
Small combustion chamber and high combustion temperature so that evaporation is relatively faster
Good overall heat transfer due to the number of passes.
Relatively higher thermal efficiency than other boilers
Packaged Boilers
In this boiler, the classification is based on the number of passes, namely how often the combustion gas passes through the boiler. In general, the type of boiler that is commonly used is a 3-pass unit with 2 sets of chimney pipes and exhaust from the back of the boiler.
