Natural gas as fuel for steam boiler not only has many advantages but also has disadvantages. The following below are disadvantages of steam boiler if using gas as its fuel:
- Location of boiler should near location of natural gas exploration or at least transmission natural gas pipeline can be reached economically.
- If in the economic range distance of transmission natural gas pipeline there is not water which has good quality to be supplied into steam boiler or to be used for cooling system in condenser steam turbine, so additional cost is required to make water treatment or make cooling water treatment such as condenser or cooling water.
- Need additional equipment and instrument to design and install natural gas piping to burner for safety reason because natural gas will be more danger than using oil fuel or solid fuel. So the investment cost for safety requirement is required.
