Before: Top mounted three burners oven maintains inside oven temperature i.e. 150 0 C for full baking of Cowl body.

After:After Consultation with OEM and Internal Quality controller, we found baking of Cowl after sealant paint at 110 0C at its pregel stage, which fulfills the requirement. Accordingly one Burner out of three Burners has been stopped.

After CED process , Seam Sealant and Under body sealant is applied on body. After Sealant application it goes for baking in sealant Oven at 150 C. After Baking body goes for sanding , top coat application and again baking up to 150C. So sealant gets baked twice in one cycle.

Introducing New Products becomes more essential in the situation where the market is keen about fuel efficiency & alternate fuels with least impact on the environment.

Lucknow Plant constantly focuses on NPI (New Product Introduction) to a great extent.

The number of NPI rose to 98 from 62 nos till last year. We also monitor the Percentage contribution of the New Products in terms of Performance, Volume & Revenue to ensure effectiveness in addition to the NPI index.

LPG Burners

Before :

Method used to raise the water temperature:-LPG burner were used to raise the temperature of water to 60C.

Post Wash operation:-After the quenching process the metaquench42 oil layers needs to be cleaned from the components. To remove this oil layer we perform the post wash operation in which the components are dipped and wash with the spray of warm water which is maintained at the temperature of 60C.

Post Wash Tank

Conservation of electricity through utilization of temperature from heated waste gases to heat water in post wash chamber

Innovation Project :

MACHINE : 200 Kg/Hr CCHF


LPG Burners

(Partial Load)

Method used to raise the water temperature:-Now a modification is made in the system in which the heat of the flue gases are extracted and used to raise the temperature of water used for post wash.

The temperature of flue gases when burnt is 275C and with the help of heat exchanger we recovered the heat. And this extracted heat is used to raise the water temperature of post wash to the required level.

Optimisation of Cooling Zone Fans operation at Paint Shop

Paint shop gets the Cowl from BIW Shop (Weld shop) for painting. In Paint shop, it passes first from Pretreatment stage, where oil, grease, dust & dirt is removed by hot water spray. Next, the Cowl body passes from Phosphate Station to make it ready for primer coat in ED (Electro- Deposition).

A layer of primer is applies over the surface of cowl by CED process and reaches to the oven for baking & drying at defined temperature i.e. 150C. This oven is horizontally connected with cooling zone, where cowls gets cooled by two axial flow fans i.e.. 22KW & 30 KW.Before:The Cooling Zone - Axial flow fans are interlocked with the Pretreatment Stage conveyor as shown below. The Cooling fans automatically comes into operation as soon as the conveyor starts. It is found always in running mode once the line gets started. Cowl takes almost 2 hrs time to reach the oven from Pretreatment stage.

Energy Management Cell Implementation Methodology


Frequency of review of energy consumption and energy conservation projects: Daily, Weekly, Monthly Quarterly, Half-yearly & Annually

Daily Energy Consumption Performance Report: -Daily monitoring, analyzing and reporting of various key energy resources such as Electricity, Water, Compressed Air,

Fuels. The Report is analyzed in detail at each shop Level in-charge w r t to production activity on daily basis. The daily Energy Performance vis--vis target is also displayed at shop floor to increase the awareness within entire teams in the shop.Monthly Performance Report: -

Monthly report is generated on the basis of data from monthly consumption along with data of production and indicates the Monthly and cumulative Performance Ratios of major areas like CV,IBF,TMML,HT shop. All the Sp. energy, Sp. Compressed air, Sp. Compressed air is reported to the individual departmental heads.

Monthly Report To Plant Head & Divisions: -Executive summary Report giving monthly and cumulative performance and the variance with respect to targets set ,

previous year's performance, etc for the whole year and the corresponding period is sent to respective Divisional Heads for information & initiating necessary improvement actions. The report is also send to Plant Head for his perusal & information. Plant Head also reviews the Monthly report in the monthly Variable Conversion Cost (VCC) review meeting.

Quarterly Performance Report:-This report gives the consumption, Monthly and cumulative, performance trends, and efforts taken. This report is sent

to Plant Head (CVBU - Pune) & respective Divisional Heads.

Half yearly Performance Feed back to Plant Head & Divisions: -

The performance of the Divisions with reference to the target both monthly and cumulative along with the performance expected to achieve w r t the Target.

Annual Performance Report: -This report giving consumption performance of various areas along with the efforts taken by various Divisions. This

report is released to - Finance Division as Input for disclosures for Director's Report.

Energy Management Cell Prepares the Energy report Daily, Monthly( M), Quarterly (Q), Half-yearly (H) & Annual reports. Plant Head & MD reviews M, QY, HY, Annual reports
