Types of Boilers

Unfired Pressure Boiler: Utilizes external sources to obtain pressure.
Power Boiler: Generates steam or vapor at pressures exceeding 1.055 kg/cm² through direct heating.

Additional Boiler Types

Locomotive Boiler: Mounted on rail vehicles, designed for steam generation for locomotion.
Portable Boiler: Self-contained, internally fired, and intended for temporary operational locations.

Specific Boiler Dimensions

Miniature Boiler: Maximum working pressure of 7.03 kg/cm²; dimensions include 405 mm diameter and 1,065 mm overall length.
Low Pressure Heating Boiler: Operates at pressures not exceeding 1.055 kg/cm² and steam water temperatures capped at 121°C.

Pressure Classifications

Medium Pressure Heating Boiler: Operates at pressures not exceeding 103.5 Mpa, with steam or water temperatures not exceeding 130°C.
Hot Water Supply Boiler: Supplies hot water externally, distinct from its own heating mechanism.

Special Categories of Boilers

Second Hand Boiler: Refers to a boiler whose location and ownership have changed post-initial use.
Condemned Boiler: Identified as unsafe to operate after inspection.
