What is package type boiler?
A package boiler is a factory-made boiler. Package boilers are available in a range of standard designs. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. Package boilers are low pressure designs.
What is fire tube package boiler?
A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
How a package boiler works?
How does it Work? Package boilers can be water-tube or fire-tube. They use fuel in the form of gas or liquid. By igniting this fuel in the combustion chamber, they create explosion inside the boiler and remain in this state with the help of a fan that forces air into the chamber and creates a tornado effect.
How does a 3 pass boiler work?
A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel. The design extracts heat from three times as much interior surface area of the boiler, compared to a single-pass, “pin-type” boiler design.
What is HRT boiler?
Horizontal return tubular boiler (HRT) has a horizontal cylindrical shell, containing several horizontal flue tubes, with the fire located directly below the boiler’s shell, usually within a brickwork setting.
What is two pass and three pass boiler?
A two-pass heater has a single coil. Burner gases make two passes through the heater. They first pass through the inside of the coil, then around its outside. A three-pass heater has two coils, a smaller coil inside a larger coil, separated by a small gap.
How many passes water tube boiler?
Number of passes – each time exhaust gas passes through the boiler, is referred to as a pass. Fire tube boiler typically have three or four passes, although one and two pass boilers are also in use.

What is a D type package boiler?
The D-type Package Boiler. The D-type boiler has a water drum, steam drum, and generating tubes. Water flows into the steam drum, flows down the downcomers and into the water drum. Water is then sent from the water drum through the generating tubes, where the fire is located around causing water molecules to boil off into steam.
What is an O type package boiler?
O-Type Package boiler. The boiler has two drums, one water drum, and one steam drum. The combustion chamber is in the middle surrounded by downcomers and generating tubes. The O-type boilers are a little simpler compared to D-type and A-type.
What are the parts of a boiler?
The boiler has two drums, one water drum, and one steam drum. The combustion chamber is in the middle surrounded by downcomers and generating tubes. The O-type boilers are a little simpler compared to D-type and A-type. They consist of one water drum and one steam drum. Generating tubes are lined up from either side of the steam and water drums.
