ENERGY SAVING TIPS

vTHERMODYNETHERMODYNE ENGINEERING SYSTEMS

ENERGY SAVING-DAY 1Periodically monitor flue gas composition and tune your boiler to maintain excess air at optimum level

vTHERMODYNE

Recover heat from boiler blow down by using heat exchanger to preheat boiler makeup waterENERGY SAVING-DAY 2

vTHERMODYNE

Install an automatic blowdown control system as it optimizes blowdown rates by regulating water discharged in relation to dissolved solids present in waterENERGY SAVING-DAY 3

vTHERMODYNE

Clear boiler waterside heat transfer surfaces to prevent scaling in boilerENERGY SAVING-DAY 4

vTHERMODYNE

Insulate steam distribution and condensate return lines to reduce energy losses by 90%ENERGY SAVING-DAY 5

vTHERMODYNE

Install removable insulation on valves and fittings and also on components requiring periodic inspection or repairENERGY SAVING-DAY 6

vTHERMODYNE

Upgrade boiler with new energy efficient burner if repair costs become excessive ENERGY SAVING-DAY 7

vTHERMODYNE

Conduct burner maintenance at regular intervals and install smaller burner on boiler that is oversized relative to its steam loadENERGY SAVING-DAY 8

vTHERMODYNE

Develop and implement a routine inspection and maintenance program to check steam traps and steam lines for leaks. Repair leaks and replace faulty steam traps as soon as possible.

ENERGY SAVING DAY 9

vTHERMODYNE

Obtain the services of a water treatment specialist to prevent system scale and corrosion and to optimize cycles of concentrationENERGY SAVING-DAY 10

vTHERMODYNE

Install economizer as it recovers heat from hot flue gases and preheats feed waterENERGY SAVING-DAY 11

vTHERMODYNE

Install air preheater as it recovers heat from hot flue gases and transfers this heat to incoming air for efficient combustionENERGY SAVING-DAY 12

vTHERMODYNE

Develop and implement a boiler tuning program to be completed a minimum of once per operating yearENERGY SAVING-DAY 13

vTHERMODYNE

Consider installing turbulators on 2-3 pass boilers as turbulators can be a cost-effective way to reduce the stack temperature and increase the fuel to steam efficiencyENERGY SAVING-DAY 14

vTHERMODYNE

Improve efficiency of boiler through maximizing the return of hot condensate to the boilerENERGY SAVING-DAY 15

vTHERMODYNE

Use variable speed drives on large boiler combustion air fans with variable flowsENERGY SAVING DAY 16

vTHERMODYNE

Clean burners,nozzels,strainers and inspect oil heaters for proper oil temperatureENERGY SAVING-DAY 17

vTHERMODYNE

Consider multiple or modular boiler units instead of 1 or 2 large boilers ENERGY SAVING-DAY 18

vTHERMODYNE

Make sure that boiler duty is at optimum efficiency. For example, dont use two boilers at 30 percent output if you can run one at 60 to 70 percent output ENERGY SAVING-DAY 19

vTHERMODYNE

If you measure steam or gas, measure the mass flow, not the volume flow. It takes ten times the energy to create 1 m3 of steam at 10 bar than at 1 bar, yet the volume is the same ENERGY SAVING-DAY 20

vTHERMODYNE

Make sure you are only generating what you need. Measure the demand and compare it with what the boiler is generating. This will ensure youre not wasting steam heating up your factory instead of your processENERGY SAVING-DAY 21

vTHERMODYNE

Steam metering throughout the entire distribution system is crucial for good energy management and to identify and implement energy saving measuresENERGY SAVING-DAY 22

vTHERMODYNE

Remove soot deposits when flue gas temperature rises 40C above the normal. A coating of 3mm thick soot on the heat transfer surface can cause an increase in fuel consumption of as much as 2.5%.

ENERGY SAVING-DAY 23

vTHERMODYNE

Recover heat from steam condensate. For every 6C rise in boiler feed water temperature through condensate return, there is 1% saving in fuel.

ENERGY SAVING-DAY 24

vTHERMODYNE

Boilers should be monitored for flue gas losses, radiation losses, incomplete combustion, blow down losses, excess air etc. Proper control can decrease the consumption upto 20%.

ENERGY SAVING-DAY 25

vTHERMODYNE

Stop steam leakage. Steam leakage from a 3 mm-diameter hole on a pipeline carrying steam at 7kg/cm2 would waste 32 kl of fuel oil per year amounting to a loss of Rs. 3 lakh.

ENERGY SAVING-DAY 26

vTHERMODYNE

Install a dial type thermometer at the base of the stack to monitor the exhaust flue gas temperatureENERGY SAVING-DAY 27

vTHERMODYNE

The refractory should be checked at least once in a month for their condition. Any damage in the refractory will lead to localized heating of the shell and damage to the same.ENERGY SAVING-DAY 28

vTHERMODYNE

Keep a check on the content of combustion gases using flue gas analyzer to adjust the air fuel ratio accordingly

ENERGY SAVING-DAY 29

vTHERMODYNE

Optimize the deaerator vent rateENERGY SAVING-DAY 30

vTHERMODYNE

Recover thermal energy from waste water streamsENERGY SAVING-DAY 31
