Pollution Control Board Guidelines Limit Gas Emissions at Controlled Temperatures. Cooling every metre cube of Waste Gases is a big cost to the industry. And if you use these Waste Gases for Waste Heat Based Generation, you can add 1 MINR per 10 metre cube per minute per 500 Deg C Waste Heat Utilised.

Waste Heat Recovery Based Generation has been the key to the success of the Sponge Iron Industry in the recent past. If you have not set up Waste Heat Generation, you are losing over 750 INR per tonne of Sponge Iron produced!

Tapsi can provide a Single Point Turnkey Solution for Waste Heat Recovery Based Power Generation and FBC Boiler Based Captive for Sponge Iron Projects. We have the best mix of American, German, Polish, Hungarian, Korean, Chinese and a combination other International Technologies to meet Customers' Technical and Budgetary requirements.


Energy Audit & Efficiency Improvement Services

Expertise to carry out Energy Audits on...

• Boilers
• Co-Generation facilities
• Waste Heat Recovery System
• Material and Energy balances of Process Plants
• Pumping Systems
• Compressed Air Systems

• Power Generating Stations
• Milling & Grinding Circuits
• Cooling Towers

Energy Audit methodology involves...
• Identification of all Energy Systems
• Evaluation of the condition of the systems
• Analysis of the impact of improvements to those systems
• Preparation of an Energy Audit Report

·         Preliminary Audit

o   To prioritise energy efficiency objects and determine the need for a more detailed audit

·         General / Detailed Audit

o   To identify all energy conservation measures appropriate for the facility given its operating parameters. A detailed financial analysis is performed for each measure based on detailed implementation cost estimates, site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation.

·         Investment-Grade Audit

o   To provide a dynamic model, energy use characteristics of both existing facility and all energy conservation measures are identified. This gives guaranteed savings from the implementation of energy projects. This grade of audit can also be used for the purpose of Benching by Regulators or a certain Regulator's Benching Compliance.
