Energy conservation opportunities in steam system

• Use back pressure steam turbines to produce lower steam pressures.

• Install PHE based hot water system in place of direct steam injection system

• Ensure that piping, valves, fittings and vessels are well insulated.

• Use more-efficient steam de-superheating methods.

• Optimize the deaerator vent rate.

• Ensure process temperatures are correctly controlled.

• Maintain lowest acceptable process steam pressures.

• Reduce hot water wastage to drain.

• Clean boiler heat transfer surfaces on regular intervals.

• Install pressure reducing station for low steam pressure.

• Remove or blank off all redundant steam piping.

• Replace non working line steam traps.

• Improve water treatment to minimize boiler blow down.

• Ensure condensate is returned or re-used in the process.

• Preheat boiler feed-water.

• Isolate steam from unused lines.

• Recover energy from boiler blowdown.

• Minimize excess combustion air.

• Use high pressure condensate to make law pressure steam.

• Check operation of steam traps.

• Remove air from indirect steam using equipment.

• Inspect steam traps regularly and repair malfunctioning traps promptly.
