OVERVIEW
Tighter control of sulfur oxides (SOx), nitrogen oxides (NOx) and particulate matter (PM) has become a priority for many utility and industrial power plants in India. Even with revised compliance deadlines for coal plant emissions, an estimated 150 GW of operating Indian coal-fired power plants and all new plants built in India’s future will be impacted by varying levels of SOx and NOx regulations.
Session 1 - Low-CAPEX NOx Emission Control
The revised NOx emission control standards of 450 mg/Nm³ by the MOE&F impacts all existing power plants commissioned between 2004 and 2016. The current preferred approach for NOx reduction projects is generally to modify the combustion systems of Boilers as it is the most optimum solution in terms of CAPEX and OPEX.
The first part of this two-part webinar series, Isgec and its licensing partner BHI FW will discuss how smart & cost-effective NOx emission control strategies can be deployed by Indian power plants targeting the 450 mg/Nm³ emission standard. These strategies make the best use of a unit’s boiler, fuels fired, baseline conditions, and available in-furnace technologies. Some of the key topics in this webinar will be:
Focus on preventing NOx formation in the first place by implementing various approaches to modify the existing combustion system of the Boilers.
Optimizing staging of direct NOx reduction methods – Combustion Controls, Low NOx Burners, Overfire Air and Windbox Modifications
In addition, case studies where NOx control optimizations were conducted will be discussed.
In the first case, the main windbox of a 575 MW Tangentially Fired Boiler in the US was modelled to evaluate the air flow distribution and subsequent modifications recommended based on the result. A second project at a 150 MW Tangentially Fired Boiler in India will be discussed where addition of Secondary Over Fire Air (SOFA) resulted in making the Boiler compliant with the latest NOx emission norms.
Session 2 – CFB Scrubbers Makes a Strong case for SOx Emission Control in India
By 2024, SOx emissions for all currently operating plants in India that are 500 MWe or larger must not exceed 200 mg/Nm³ and all new plants must meet even tighter SOx limits of 100 mg/Nm3.
Until now, wet flue gas desulfurization (WFGD) technology has been the default FGD technology option largely due to its track record on large scale units, and its ability to produce gypsum as a by-product for possible sale.
In contrast, circulating fluidized bed scrubber (CFBS) technology is becoming an increasingly attractive option for both existing and new power plants. The CFBS efficiently and economically captures a wide array of pollutants, including SO2, SO3, HCl, PM, heavy metals, and organic compounds. Its installed cost is approx. 30% lower than WFGD, uses less water, requires no stack modifications, and can handle fuels with a wide range of sulfur content. Additionally, its recent success with large scale installations in many parts of world make it the ideal choice for plants ranging from small waste-to-energy plants to large coal utility power plants.
In this session, Isgec and its licensor Sumitomo SHI FW (SFW), will focus on the technical, economic, and environmental benefits of CFB scrubbing technology for Indian power plants.
Important Topics to be Covered:
What are the differences in pollutant capture performance between Wet FGD and CFBS technologies?
How do the CAPEX and OPEX compare between the technologies?
How big can CFBS systems get?
How does the water consumption for the CFB scrubber compare with that of a wet FGD?
What turn-down capability do you have with the CFB scrubber?
Will the CFB scrubbing technology work with an ESP instead of a baghouse?
How does the CFB scrubber footprint compare to that of a wFGD?
What is the experience range of fuels and plant sizes with CFBS technology?
Relevant case studies of plants worldwide using SFW’s CFB scrubber technology will be presented:
Dry Fork Station, Basin Electric Power Corporation (BEPC), USA a 420 MW PRB coal-fired plant in Wyoming (USA). Behind its pulverized coal boiler sits the largest single absorber dry scrubber operating in the world today. The plant has demonstrated a 98% availability since its commissioning in 2012.
