INSTRUCTIONS TO APPLICANTS

1.0INTRODUCTION

NTPC was incorporated in the year 1975, with the objective of planning, promoting and organizing an integrated development of Power Stations in India. With an installed capacity of above 45000 MW, NTPC is the largest power generating major in the country. NTPC designated as one of the Maharatna Public Sector Undertaking is poised to become a global giant and the mega power utility has ambitious plan to become 1,28,000 MW plus company by 2032. To realize its goal of becoming 1,28,000 MW Company by 2032, NTPC already has a long list of projects in pipeline.

Sixty-seven (67) numbers of various unit size (mostly 200 & 500 MW size) coal based thermal units installed before 31st Dec, 2003 with cumulative capacity of18185 MW, are operational without having any DeNOx system. This emission value has to be brought down to 600 mg/Nm3.

Coal fired units under operation, installed after 31st Dec, 2003, are 31 in nos having different unit sizes (mostly 500 & 660 MW size). These have cumulative generation capacity of 15590 MW. For these NOx emission level is to brought down to 300 mg/Nm3.

Further, thirty -seven (37) numbers of coal fired units of cumulative capacity 22185 MW are under construction with advanced combustion system in order to reduce the NOx. These units are guaranteed for NOx emission of 260 g/GJ of heat input. These plants are expected to be commissioned within 1-2 years time. This emission value has to be brought down to 100 or 300 mg/Nm3 based on the date of installation.

We are willing to install a small pilot level SCR demonstration plant by taking slip stream (around 1500 Nm3/hr) at our own expense. Information collected from this pilot plant would be useful for selection and designing of SCR System suitable for Indian coal(s).This test will be performed along with involvement of NTPC and we will share the outcomes of the test along with all data collected during the test with NTPC. Detail of this proposal is attached herewith. We request that consumable (i.e. Power, water, auxiliary steam, compressed air and Ammonia etc) required during study shall be provided by NTPC. Required quantity of same is indicated in our proposal. In case a coal fired unit is offered to us for the pilot test, we will discuss and finalise detailed test protocol with NTPC within 2 week’s time.

Proposal shall cover the following:-

1.Purpose

2.Scope of work

3.Test facility details with diagram

4.Test method

5.Erection Schedule

6.Test schedule

7.Test conditions

8.Shut down time required

9.Utility required from Employer

10.Measurement –All additional instrument required shall be arranged by Applicants

11.Collected data to be shared

12.Result

*In case applicant do not manufacturer their own catalyst then demo plant of their associate/ sub-vendor of catalyst supplier may be proposed.
