REQUIREMENTS OF A GOOD BOILER

A good boiler should possess the following qualities:

1. It should be able to generate steam at the required pressure and quantity with minimum fuel consumption.
2. Its initial cost, installation, maintenance, and operational cost should be as low as possible.
3. It should occupy a small floor area and should be light in weight.
4. It should be able to meet the fluctuating demands of steam without fluctuations in steam pressure.
5. All parts of the boiler should be easily accessible for cleaning, inspection, and maintenance.
6. It should have minimum joints to avoid leakage of steam.
7. Its erection time should be reasonable with minimum labour.
8. The velocities of water and flue gas should be high for better heat transfer with minimum pressure drop through the system.
9. There should be no deposition of mud and foreign materials inside the surface and soot deposits on the outside surface of heat-transferring parts.
10. The boiler should conform to safety precautions as laid down in the Boiler Regulations.
