Package boiler

Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants.

Discarding most of the entropy caps the thermodynamic efficiency below the range needed to make a low pressure boiler suitable for a co-generation plants even when the available capacity is adequate for the application.

Advantages of package boilers are that they can be delivered and installed as a complete insulated assembly that doesn’t require a large exclusion zone around itself.

These boilers are inexpensive to operate because their automatic burner management system doesn’t require continuous supervision and they have low scheduled maintenance costs.

Because the burner’s blower delivers combustion air, the over-fire draught negative pressure required is nearly nil.

Stack height need only be sufficient for structure safety and to clear the nuisance of the exhaust fumes.

The tall chimney needed to provide a large negative pressure to draw combustion air through a bed of solid fuel is not required.

In most installations a barometric damper is used to maintain a constant over-fire draught so that the air to fuel ratio remains constant instead of increasing with the increasing draught available at the stack as the outdoor temperature falls.

Generating tubes filled with water are in direct contact with the heat source inside the boiler, causing damage to the pipes as well as scaling.

Such package boilers do not require purifiers (filters) because they burn consistently removing all contaminants within the fuel.

Other essentials such as burner electronics provide auto-ignition and on-demand lighting feature that monitors the flame and pressure within the boiler.
